## Summary
When the backend serves both `api.stack-auth.com` and `api.hexclave.com`
from the same deployment, signed JWT `iss` claims and OAuth
`redirect_uri` values need to match the host the customer's SDK actually
talks to — otherwise customers with hardcoded issuer checks or
registered OAuth callback URLs break when their SDK upgrades. This PR
makes both follow the request host.
Closes the "Interpretation B" plan from our earlier discussion.
## Changes
### Backend — request-host-derived `iss` and `redirect_uri`
- **New helper**
[`apps/backend/src/lib/request-api-url.ts`](apps/backend/src/lib/request-api-url.ts)
exports `getApiUrlForRequest(req)` and `getApiUrlForHost(host)`. A
consolidated `CLOUD_HOST_PAIRS` constant is the single source of truth
for the stack-auth ↔ hexclave host pairs (prod, dev, staging). Both the
allowlist here and the validator alias map in `tokens.tsx` derive from
it, so they can never drift again.
- **JWT issuer per request**
([`apps/backend/src/lib/tokens.tsx`](apps/backend/src/lib/tokens.tsx)) —
`getIssuer` now takes `apiUrl`.
`generateAccessTokenFromRefreshTokenIfValid` and `createAuthTokens`
accept an `apiUrl` parameter that flows into the `iss` claim.
`getAllowedIssuers` stays env-driven with the bidirectional alias map,
so tokens cross-validate across hosts.
- **OAuth `redirect_uri` per request** — all 12 providers +
`MockProvider` now take `apiUrl` and use it to build `redirect_uri =
apiUrl + "/api/v1/auth/oauth/callback/<provider>"`. `getProvider()`
accepts an `{ apiUrl }` option and forwards it.
- **OAuth2Server factory** — the module-level `oauthServer` singleton
became a per-request `createOAuthServer({ apiUrl })` factory so
`OAuthModel.generateAccessToken` mints tokens with the right `iss`. Used
in the callback route, the token route, and the cross-domain-authorize
helper.
- **Token-minting call sites updated** — all 10 `createAuthTokens`
invocations (password sign-up/sign-in, sessions create,
sessions/current/refresh, anonymous sign-up, apple-native callback,
MFA/OTP/passkey sign-in, OAuth model token exchange), plus the
CLI-complete `generateAccessTokenFromRefreshTokenIfValid` direct call,
now pass `getApiUrlForRequest(fullReq)`.
- **`createVerificationCodeHandler` refactored** to pass `apiUrl` as a
6th positional arg to the user's handler, so MFA/OTP/passkey sign-in
flows get the same per-request `iss` as the rest. The other 8 callers
(password-reset, contact-channels-verify, etc.) don't need changes —
they accept fewer args and TS function-arity compatibility makes that
fine.
### SDK — freeze `@stackframe/*` defaults at stack-auth.com
-
[`packages/template/src/lib/stack-app/apps/implementations/common.ts`](packages/template/src/lib/stack-app/apps/implementations/common.ts)
reverts `defaultBaseUrl` and `defaultAnalyticsBaseUrl` to
`https://api.stack-auth.com` / `https://r.stack-auth.com`. A customer
who upgrades their `@stackframe/*` package to the latest version without
explicitly migrating to `@hexclave/*` keeps hitting `api.stack-auth.com`
and never sees their JWT `iss` or OAuth `redirect_uri` change.
- The `@hexclave/*` mirror packages are unaffected because they were
published from source when `defaultBaseUrl =
"https://api.hexclave.com"`; v1.0.0 already targets the hexclave host on
npm. Extending `scripts/rewrite-packages-to-hexclave.ts` to substitute
these literals during future republishes is a separate follow-up.
### Docs — migration guide rewrite
- [`docs-mintlify/migration.mdx`](docs-mintlify/migration.mdx) rewritten
concisely. Spells out the two host-visible changes that require
pre-deploy action when migrating to `@hexclave/*`: updating manual JWT
verifier code (with the array-of-issuers pattern) and updating OAuth
callback URLs at each provider (with the GitHub-OAuth-Apps single-URL
caveat explicitly called out).
## What was deliberately left out
- **Rewriter pipeline extension** for `@hexclave/*` republishes —
separate follow-up.
- **Cross-SDK defaults** (Swift, stack-cli, init-stack still default to
`api.hexclave.com`) — out of scope per discussion.
- **Dashboard launch-checklist host-awareness** — out of scope per
discussion (callback URLs stay hexclave-branded in the dashboard UI).
## Verification
- `pnpm typecheck` — 29/29 packages pass.
- `pnpm lint` — 29/29 packages pass.
- Five parallel review agents (JWT, OAuth, helper, migration guide, SDK
defaults) + an external review of the commit caught four real issues —
all resolved in the same commit before push:
- Missing `api.staging.*` entries in `issuerHostAliases` (would have
broken cross-host token validation on staging).
- Stale comment in `apps/backend/src/stack.tsx`.
- Misleading "backward-compat" comment in `getHardcodedFallbackUrls`.
- MFA/OTP/passkey using env-var fallback for `iss` instead of the
request host.

## Summary by cubic
Makes JWT issuers and OAuth redirect_uri values follow the incoming
request’s host so tokens and redirects always match `api.stack-auth.com`
or `api.hexclave.com`. Also freezes `@stackframe/*` SDK defaults to
Stack Auth and tightens the migration guide to focus on OAuth callbacks.
- **New Features**
- Added `request-api-url` helper with an allowlist of cloud hosts;
unknown hosts fall back to the deployment’s API URL.
- JWT `iss` now uses the per-request API URL; validation accepts both
brands via aliases derived from one `CLOUD_HOST_PAIRS` source.
- All OAuth providers build `redirect_uri` from the request host;
`getProvider()` now takes `{ apiUrl }`.
- Replaced the OAuth2Server singleton with per-request
`createOAuthServer({ apiUrl })` so token exchange mints with the right
issuer.
- Updated token-minting and OAuth routes to pass the API URL;
verification-code flows receive it; connected-accounts refresh paths
safely pin the deployment default.
- SDK: `@stackframe/*` defaults point to `https://api.stack-auth.com`;
`@hexclave/*` mirrors remain hexclave-branded.
- Shared: updated fallback API host lists to include both stack-auth and
hexclave hosts.
- **Migration**
- Update each provider’s OAuth callback URL to
`https://api.hexclave.com/api/v1/auth/oauth/callback/<provider>` when
migrating to `@hexclave/*`.
- If you verify JWTs manually, update the expected issuer to the
hexclave host (including anonymous/restricted variants).

## Summary
**Stacked on [#1475](https://github.com/hexclave/stack-auth/pull/1475)**
(`cl/hexclave-pr1`, the invisible compatibility layer). Diff vs that
base = the actual PR 2 code.
This is **PR 2 of the Stack Auth → Hexclave rebrand: the visible flip**.
Old wire identifiers (cookies, request/response headers, Bearer prefix,
JWT issuers, MCP tool name) keep working indefinitely via PR 1's
dual-accept. This PR flips every user-visible surface — package names
taught in docs, SDK class names in code examples, dashboard setup
snippets, page titles, error messages, email content, CLI binary,
default base URLs, GitHub repo slug, contributor guidance — to the
Hexclave brand.
See [`RENAME-TO-HEXCLAVE.md`](./RENAME-TO-HEXCLAVE.md) → *"PR 2: Rebrand
to Hexclave (visible)"* for the full per-work-area spec.
## What's implemented (per the plan's PR 2 scope)
- **SDK base URLs** flipped: `defaultBaseUrl` and
`defaultAnalyticsBaseUrl` in
[common.ts](packages/template/src/lib/stack-app/apps/implementations/common.ts:127)
→ `https://api.hexclave.com` / `https://r.hexclave.com`. PR 1's
[`getHardcodedFallbackUrls`](packages/stack-shared/src/utils/urls.tsx:199)
table now keys on the Hexclave domain.
- **Domain inventory sweep** (16 subdomains from the plan): every
`api/app/docs/discord/demo/mcp/skill/feedback/test/preview/r/api2/api.staging/idp-jwk-audience/built-with.stack-auth.com`
reference in production code, docs-mintlify, examples, READMEs, and
contributor guidance flipped to `*.hexclave.com`. Carve-outs: PR 1's
intentional JWT issuer dual-accept table in
[tokens.tsx](apps/backend/src/lib/tokens.tsx), the legacy `./docs/`
folder, the `unified-docs-widget` allowlist (deliberately accepts both
during DNS transition), and `url-targets.ts` hosted-component default
(baked into existing customer deploys).
- **`@deprecated` JSDoc** on every `Stack*` public export
([packages/template/src/lib/stack-app/index.ts](packages/template/src/lib/stack-app/index.ts)
+ [packages/template/src/index.ts](packages/template/src/index.ts)) —
`StackClientApp`, `StackServerApp`, `StackAdminApp` + every
constructor/options/JSON type, `StackHandler`, `StackProvider`,
`StackTheme`, `useStackApp`, `defineStackConfig`, `StackConfig`.
Hexclave\* aliases are now canonical.
- **Runtime `console.warn`**
([packages/template/src/internal/deprecation-warning.ts](packages/template/src/internal/deprecation-warning.ts))
— once-per-process when the SDK is loaded from a `@stackframe/*`
artifact. Detection uses the existing
`STACK_COMPILE_TIME_CLIENT_PACKAGE_VERSION_SENTINEL` (rewritten at build
time to e.g. `js @stackframe/stack@2.8.92` or `js
@hexclave/next@1.0.0`); `@hexclave/*` mirror artifacts short-circuit the
warning.
- **Tier 3 data migration**: new idempotent SQL migration
[`20260523000000_rename_internal_project_to_hexclave`](apps/backend/prisma/migrations/20260523000000_rename_internal_project_to_hexclave/migration.sql)
— updates the internal Project `displayName` 'Stack Dashboard' →
'Hexclave Dashboard' and `description` only if both still hold the
pre-rebrand defaults. Operator-renamed projects untouched, missing row
no-ops, re-runs are no-ops. [`seed.ts`](apps/backend/prisma/seed.ts:87)
default flipped. `getSharedEmailConfig("Stack Auth")` → `("Hexclave")`.
- **Tier 4 brand strings** (mechanical sweep, ~340 files):
- Page + OpenAPI titles (Hexclave API / Dashboard / REST API / Webhooks
API / Documentation). OpenAPI `info.description` documents
`X-Hexclave-*` headers as canonical with compat note on `X-Stack-*`.
- `HexclaveAssertionError` message text
([errors.tsx:71](packages/stack-shared/src/utils/errors.tsx:71)) — "an
error in Stack." → "an error in Hexclave."
- Known-error message templates
([known-errors.tsx](packages/stack-shared/src/known-errors.tsx)) flipped
to lead with `x-hexclave-*` + the new `docs.hexclave.com` URL; legacy
`x-stack-*` mentioned as compat aliases. **25 e2e test files updated in
lockstep**.
- Email content: failed-emails-digest body, sendTestEmail recipient (now
`sent-with-hexclave.com`), test-email-recipient default.
- `CHANGELOG.md` title → "Hexclave Changelog".
- `AGENTS.md` env var convention: new vars prefix `HEXCLAVE_` /
`NEXT_PUBLIC_HEXCLAVE_` for Category A/B; legacy `STACK_*` explicitly
noted as accepted via PR 1's dual-read.
- **CLI / init wizard**:
- Every dashboard setup snippet, init-stack template, and docs-mintlify
page teaches `npx @hexclave/cli@latest init` (was
`@stackframe/stack-cli`).
[setup-page.tsx](apps/dashboard/src/app/(main)/(protected)/projects/[projectId]/(overview)/setup-page.tsx)
+
[link-existing-onboarding](apps/dashboard/src/app/(main)/(protected)/(outside-dashboard)/new-project/page-client-parts/link-existing-onboarding.tsx).
- [init-stack](packages/init-stack/src/index.ts:634)
`STACK_*_INSTALL_PACKAGE_NAME_OVERRIDE` defaults flipped to
`@hexclave/*`.
- Generated `stack/client.ts` / `stack/server.ts` import from
`@hexclave/next` and reference `HexclaveClientApp` /
`HexclaveServerApp`.
- Internal `StackAuthKeys` dashboard component renamed to
`HexclaveKeys`.
- **docs-mintlify rewrite** (legacy `./docs/` intentionally untouched
per scoping decision):
- **78 MDX files swept**.
`@stackframe/{react,stack,js,tanstack-start,...}` →
`@hexclave/{react,stack,js,...}` in install snippets and code blocks;
`Stack*` SDK class names → `Hexclave*` in all code examples; 'Stack
Auth' brand phrase → 'Hexclave'.
- `openapi/{server,admin,client,webhooks}.json` titles → 'Hexclave REST
API' / 'Hexclave Webhooks API'.
- **Generators flipped before regeneration**:
-
[`packages/stack-shared/src/helpers/init-prompt.ts`](packages/stack-shared/src/helpers/init-prompt.ts),
[`/ai/prompts.ts`](packages/stack-shared/src/ai/prompts.ts),
[`apps/backend/src/lib/ai/prompts.ts`](apps/backend/src/lib/ai/prompts.ts),
[`apps/backend/src/lib/ai/tools/create-email-{template,draft}.ts`](apps/backend/src/lib/ai/tools/create-email-template.ts),
[`apps/skills/src/app/route.ts`](apps/skills/src/app/route.ts) (taught
MCP tool → `ask_hexclave` with compat note; CLI binary teach →
`hexclave`),
[`docs-mintlify/snippets/home-prompt-island.jsx`](docs-mintlify/snippets/home-prompt-island.jsx),
[`packages/template/README.md`](packages/template/README.md) +
integrations/convex/component/README.md.
- `generate-sdks` propagated changes to `packages/{react,stack,js}`.
- **OpenAPI dual-documentation**:
[`apps/backend/src/app/api/latest/route.ts`](apps/backend/src/app/api/latest/route.ts)
now lists `X-Hexclave-*` headers as primary documented schemas with
`X-Stack-*` duplicates marked `.optional()` (both accepted at runtime by
PR 1's normalize-at-proxy shim).
- **`@stackframe/emails` virtual module**: dual-aliased to
`@hexclave/emails` at the bundler boundary
([email-rendering.tsx:89](apps/backend/src/lib/email-rendering.tsx:89)).
Stored email templates continue to import from either name; new
AI-generated templates and the system prompt teach `@hexclave/emails`.
- **Tier 2 mirror-publish wiring** (new this PR, lays the groundwork for
`@hexclave/*` first publish):
-
[`scripts/rewrite-packages-to-hexclave.ts`](scripts/rewrite-packages-to-hexclave.ts)
— rewrites 9 publishable `@stackframe/*` → `@hexclave/*` `package.json`
files (reads `HEXCLAVE_VERSION` env or `--version=` flag), pins
cross-deps to the shared `@hexclave` version, registers `hexclave` bin
alongside `stack` for `@hexclave/cli`.
-
[`.github/workflows/npm-publish.yaml`](.github/workflows/npm-publish.yaml)
appended with rewrite-then-republish step. `pnpm publish` skips
already-on-npm versions so reruns are safe.
- **Sender email domain**: `noreply@stackframe.co` →
`noreply@sent-with-hexclave.com` (the dedicated transactional-sender
domain split per the plan, to isolate bulk deliverability from
`hexclave.com` reputation); `security@` / `team@stack-auth.com` inbound
mailboxes → `@hexclave.com`.
- **Self-host docs**: docker network / container names in the bash
examples flipped from `stack-auth` to `hexclave` (`hexclave-postgres`,
`hexclave-clickhouse`, `hexclave.env`). The docker image tag
`stackauth/server:latest` stays per the plan's locked decision.
- **GitHub repo slug**: `hexclave/stack-auth` → `hexclave/hexclave` in
every `package.json` `repository` field, README link, CHANGELOG
raw-asset URL.
## Carve-outs (deliberately untouched)
-
**[`apps/backend/src/lib/tokens.tsx`](apps/backend/src/lib/tokens.tsx)**
JWT issuer dual-accept table — PR 1 intentional infrastructure, kept
indefinitely.
- **Legacy `./docs/` folder** — per scoping decision (only
`docs-mintlify/` rewritten).
- **`unified-docs-widget` hostname allowlist** — accepts both
`.hexclave.com` (canonical) and `.stack-auth.com` (transition window)
for DNS rollout.
- **`url-targets.ts`** hosted-domain default
`.built-with-stack-auth.com` — wire identifier baked into existing
customer deploys; indefinite read-fallback.
- **Binary visual assets** (logos, favicons, OG images, README
screenshots) — out of scope for this PR. Need design work; tracked
separately.
## Verification
- **`pnpm typecheck`** on
`packages/{template,stack-shared,react,stack,js}` + `apps/dashboard`:
**all green**. The remaining backend / e-commerce-demo typecheck errors
are pre-existing (Prisma codegen output +
`./generated/api-versions.json` not present in fresh worktrees without
`pnpm run codegen-prisma` + a live DB) and unrelated to this diff.
- **`pnpm lint`** on the same 6 packages: all green.
- **Final grep** for residual `Stack Auth` / `stack-auth.com` /
`@stackframe/stack-cli@latest` references: zero outside the intentional
carve-outs above.
- **25 e2e test files updated in lockstep** with the known-error message
changes (asserted strings flipped to match the new x-hexclave-* +
compat-note messages).
## Deploy blockers (ops sequencing before this rebrand goes live)
This PR is code-complete, but the rebrand's visible surfaces (SDK
default URLs, dashboard links, npm READMEs, REST error messages, runtime
deprecation warning) all point at `*.hexclave.com` / `@hexclave/*`
resources that don't exist yet. None of these are fixable from a PR —
they're ops/registrar/npm work that has to be sequenced before merging
this to a release tag.
Suggested ordering, hardest blockers first:
### Tier 1 — required before customer-facing deploy (everything below
this line *will visibly break customers on day 1* if skipped)
1. **DNS + TLS for `api.hexclave.com` + `api1./api2.hexclave.com`** →
must point at the same backend that serves `api.stack-auth.com` (or a
backend that mirrors PR 1's dual-accept). The SDK's new `defaultBaseUrl`
is `https://api.hexclave.com`; every customer that relied on the old
default and upgrades to a post-PR2 SDK build sends API requests here.
Until this resolves, every default-config customer's API call NXDOMAINs.
2. **DNS for `app.hexclave.com`** → the dashboard. Referenced in the
SDK's default-error messages ("Please create a project on the Hexclave
dashboard at https://app.hexclave.com"), the init-stack flow's
`wizard-congrats` redirect, and the OAuth dashboard handoff.
3. **DNS for `docs.hexclave.com`** + Mintlify deploy → the SDK runtime
deprecation warning (`https://docs.hexclave.com/migration`), every
README, every "Learn more" link in the dashboard, and every REST API
error body (`/api/overview#authentication`) points here. The MDX is in
this PR; the docs build target needs DNS.
4. **DNS for `mcp.hexclave.com`** → the MCP server endpoint that every
taught agent integration (`claude mcp add ...`, `cursor`, `codex`,
`vscode`) registers. Until this resolves, every `npx
@hexclave/cli@latest init` MCP-registration step fails.
5. **Reserve the `@hexclave` npm scope + set repo variable
`HEXCLAVE_VERSION`** → the mirror-publish step in
`.github/workflows/npm-publish.yaml` is gated on this variable. Without
it, the entire taught onboarding command `npx @hexclave/cli@latest init`
404s from the npm registry, *and* every README that says "install
`@hexclave/next`" leads to install failure. Pick the initial version
intentionally (`1.0.0` or aligned to `@stackframe/stack`); don't accept
a silent default.
### Tier 2 — required before announcing the rebrand publicly (lookalike
or low-traffic surfaces, but visibly broken)
6. **DNS for `r.hexclave.com`** → the analytics beacon
`defaultAnalyticsBaseUrl`. Silent failure if missing (analytics drops),
but should land alongside Tier 1.
7. **Register `sent-with-hexclave.com` + full email auth (SPF / DKIM /
DMARC)** → the new default sender domain for shared-sender transactional
emails. Without it the dashboard "send test email" path emits bounces,
and shared-sender flows (`getSharedEmailConfig("Hexclave")`) deliver to
spam at best.
8. **MX + SPF / DMARC for `hexclave.com`** → `team@hexclave.com` and
`security@hexclave.com` mailboxes. The security disclosure mailbox is
referenced in [`.github/SECURITY.md`](.github/SECURITY.md);
`team@hexclave.com` is the actual recipient of internal feedback emails
sent at runtime by
[`apps/backend/src/lib/internal-feedback-emails.tsx`](apps/backend/src/lib/internal-feedback-emails.tsx).
Today, every runtime feedback email bounces.
9. **DNS for `skill.hexclave.com`** → the canonical AI-agent skill fetch
URL (the agent bootstrap pivot). Without it, the entire "agent downloads
`SKILL.md` from a known URL" flow taught in
[`packages/stack-shared/src/helpers/init-prompt.ts`](packages/stack-shared/src/helpers/init-prompt.ts)
fails.
10. **Create `github.com/hexclave/hexclave` as a public repo** (even as
a redirect to `hexclave/stack-auth`) **OR** rewrite every `package.json`
`"repository"` field + dashboard footer "view on GitHub" link to point
at `hexclave/stack-auth` (which already exists). Currently every npm
package page's "Repository" link is dead, and the dashboard's GitHub
button + dev-tool repo link are dead.
### Tier 3 — broken but low-visibility / low-traffic
11. **DNS for `discord.hexclave.com`** → Discord invite redirect, used
in every README's chip and the dashboard footer.
12. **DNS for `demo.hexclave.com`** → "✨ Demo" badge in every npm
package README. Broken-image badge on the package page.
13. **DNS + TLS for `built-with-hexclave.com`** → optional
hosted-handler domain (the default reverted to
`.built-with-stack-auth.com` in this PR's carve-outs, so this only
matters for projects that manually flip).
## Other follow-ups (not deploy-blocking)
- **E2E snapshot regen across the full suite** for the dual-emitted
`x-hexclave-*` response headers (PR 1 follow-up; `vitest -u` in CI
absorbs).
- **Binary visual assets** — logos, favicons, OG images, README
screenshots; need design pass.
- **Backend OpenAPI fumadocs regen** in CI flow — the JSON files in
`docs-mintlify/openapi/` are committed but regen runs in CI. Verify the
workflow that does this still works against the post-PR2 source.
- **Backend typecheck infra debt** — needs `codegen-prisma` +
`codegen-route-info` to clear; pre-existing, unaffected by this PR.
## Test plan
- [ ] CI runs full e2e suite (with `vitest -u` to absorb residual
snapshot deltas, then committed back).
- [ ] Spot-check: new `@hexclave/cli init` (once published) generates
`hexclave.config.ts` and works against a fresh project.
- [ ] Spot-check: existing customer with `@stackframe/stack` import sees
the once-per-process `console.warn` recommending `@hexclave/next` on SDK
init.
- [ ] Manual: dashboard setup page renders the `npx @hexclave/cli@latest
init` snippet and the `x-hexclave-publishable-client-key` API header in
the curl example.
- [ ] Manual: a fresh `pnpm run prisma migrate` against a clean DB sets
the internal project displayName to 'Hexclave Dashboard'.

## Summary
**Stacked on #1468** (`docs/hexclave-rename-plan` — the plan doc). Diff
vs that base = the actual PR 1 code.
This is **PR 1 of the Hexclave rebrand: the invisible compatibility
layer**. Everything is additive. Old SDKs, old wire identifiers, and old
env var names keep working unchanged. The backend dual-accepts and
dual-emits; new SDK code emits `x-hexclave-*` headers and the
`hexclave_` Bearer prefix; cookies dual-write; env vars dual-read across
every category. **No user-visible rebranding lands here** — that's PR 2.
See [`RENAME-TO-HEXCLAVE.md`](./RENAME-TO-HEXCLAVE.md) → *"PR 1
implementation guide"* for the full per-work-area spec, file pointers,
and chosen approach.
## What's implemented (all 14 PR-1 work-areas)
- **SDK export aliases** — `Hexclave*` aliases for the user-facing
`Stack*` exports added in `packages/template`; codegen propagates them
to `@stackframe/{js,stack,react,tanstack-start}`. React-only aliases
correctly excluded from `@stackframe/js`. (`e60550a2`)
- **JWT issuer dual-accept** — `decodeAccessToken` accepts both
`api.stack-auth.com` and `api.hexclave.com` issuers. Signing unchanged.
(`fc781def`)
- **Request-header dual-accept** — backend + dashboard proxies normalize
`x-hexclave-*` → `x-stack-*` at the existing empty proxy hook (so
`smart-request.tsx` and every route schema keep working unchanged); CORS
allowlists extended via a derive-once helper. (`2a056eac`)
- **MCP `ask_hexclave`** — registered alongside `ask_stack_auth` via a
shared helper; `ask_stack_auth` behavior byte-identical. (`30ffd604`)
- **Dev-tool** — DOM ids + header emit switched.
`window.HexclaveDevTool` exposed alongside `window.StackDevTool`.
(`32131ea7`)
- **The big consolidated commit** (`7fed864a`):
- **Env vars** — central `getEnvVariable` prefix-transform (HEXCLAVE
first, STACK fallback); dashboard + template client env files dual-read;
`turbo.json` globalEnv; `NEXT_PUBLIC_STACK_PORT_PREFIX` renamed outright
across ~82 files including docker.
- **Cookies** — dual-write/dual-read auth (`stack-access`/`-refresh-*`
and custom-domain variants), OAuth-state
(`stack-oauth-{inner,outer}-*`), and low-risk cookies (`stack-is-https`,
`stack-last-seen-changelog-version`). Bypass sites patched (backend
OAuth callback, dashboard remote-dev auth route, impersonation snippets,
snapshot serializer).
- **Bearer prefix** — SDK token parser accepts both `stackauth_` and
`hexclave_`; emits `hexclave_`. Discovery correction: this is purely
SDK-internal — the backend never parses it.
- **Response headers** — backend dual-emits
`x-hexclave-{request-id,actual-status,known-error}`; SDKs dual-read (new
first, stack fallback).
- **SDK request-header emit switch** —
`client/server/admin-interface.ts` + dashboard `api-headers.ts` +
`internal-project-headers.ts` + `feedback-form.tsx` switched to
`x-hexclave-*`. Plus `stack_response_mode` query param.
- **Storage keys** — dev-tool / cli-auth / oauth-button / docs keys
renamed (straight); `stack:session-replay:v1` dual-read so in-progress
recordings survive SDK upgrades; `stack_mfa_attempt_code` dual-read.
- **Query params** — cross-domain params dual-emit/dual-accept via
shared helpers; backend `oauth/authorize` accepts
`hexclave_response_mode` and `stack_response_mode`; `stack-init-id`
renamed.
- **`Symbol.for`** — app-internals symbol gets a parallel
`Symbol.for("Hexclave--app-internals")` getter on each attach site (no
read-site churn — old symbol still attached). 3 file-private symbols
renamed outright.
- **Config discovery** — prefer `hexclave.config.ts`, fall back to
`stack.config.ts` at every discovery site (CLI / dashboard / backend /
local-emulator); `init` writes the new filename; CLI credentials path
migrates.
- **Internal renames** — `StackAssertionError`,
`StackClient/Server/AdminInterface` renamed outright (no alias, per the
"internal-only → rename" rule). ~264 files touched.
- **Review-pass fixes** (`21217fbe`) — three real bugs found by parallel
review agents and fixed:
- `snapshot-serializer.ts` was interpolating the whole
`keyedCookieNamePrefixes` array (`${arr}`) — adding a second prefix
would have corrupted **every** OAuth-cookie snapshot, not just new ones.
- **Docker port-prefix producer/consumer mismatch** —
`entrypoint.sh`/`run-emulator.sh`/cloud-init `user-data` were still
producing `NEXT_PUBLIC_STACK_PORT_PREFIX` while the dashboard sentinel +
consumers had been renamed; silent self-host regression (custom port
prefix would be ignored).
- **Missing `hexclave-oauth-inner-*` dual-write** in the OAuth authorize
route — callback's fallback masked it but the dual-write was specified
by the plan.
- Plus: `mcp.test.ts` tool-list assertions updated to include
`ask_hexclave`; two dashboard header-emit sites switched to
`x-hexclave-*` for consistency.
- **E2E snapshot serializer follow-up** (`4b16cc5d`) —
`x-hexclave-request-id` added to the hidden-headers list (mirroring
`x-stack-request-id` treatment), and 2 sample inline snapshots
regenerated in `projects.test.ts` to include the new dual-emitted
headers.
## Verification
- **`pnpm typecheck`** — clean (the fresh-worktree `@/.source` / Prisma
codegen gap in `stack-docs` is pre-existing and unrelated).
- **`pnpm lint`** — 29/29 packages green.
- **`pnpm exec turbo run build --filter=./packages/*`** — 13/13 packages
build (including `@stackframe/stack-cli` once the dashboard standalone
is present).
- **Live E2E** against a running backend on `cl/hexclave-pr1`:
- `pnpm test run
apps/e2e/tests/backend/endpoints/api/v1/internal/mcp.test.ts` — **6/6
pass** (verifies the new `ask_hexclave` tool — the hand-written inline
snapshot matched actual MCP server output).
- `pnpm test run
apps/e2e/tests/backend/endpoints/api/v1/internal/projects.test.ts` —
**11/11 pass** (verifies wire dual-accept + dual-emit end-to-end; the
snapshot serializer fix was found and applied during this check).
A four-agent parallel **review pass** also audited the full diff for
logic/runtime bugs across the work-areas (wire headers + JWT, cookies +
bearer + symbols, env vars, query params + config + MCP + aliases). All
in-slice review verdicts were ✓ except the three bugs listed above,
which are now fixed.
## Known follow-ups (out of scope for this PR)
- **E2E snapshots across the rest of the suite** — backend now
dual-emits `x-hexclave-{known-error,actual-status}` alongside
`x-stack-*`, which legitimately appears in inline snapshots throughout
`apps/e2e`. Two were regenerated here as a sample; the rest should regen
with `vitest -u` in CI.
- **Docker shell env vars beyond `PORT_PREFIX`** — `entrypoint.sh` still
reads `STACK_*` env vars directly (the JS-side `getEnvVariable`
transform doesn't help the shell). JS consumers dual-read so it works in
practice; full shell-level dual-read is a deeper self-host follow-up.
- **`@stackframe/stack-cli` build ordering** — pre-existing; needs
`build:rde-standalone` first. Not affected by this PR.
## Test plan
- [ ] CI runs full e2e suite (with `vitest -u` to absorb dual-emit
snapshot deltas, then committed back)
- [ ] Spot-check: an old SDK build (emitting only `x-stack-*`) still
authenticates against the new backend
- [ ] Spot-check: a new SDK (emitting `x-hexclave-*` / `Bearer
hexclave_*`) still authenticates against an old backend during deploy
ordering
- [ ] Manual: `npx @stackframe/stack-cli@latest init` (new onboarding
entrypoint) generates `hexclave.config.ts`
- [ ] Manual: existing `stack.config.ts`-only project still resolves (no
migration required)

### Summary of Changes
You can now edit items on a product view.
The "Make free" button is less obtuse, and it clearly tells you what
it's going to do.
Additionally, we found out while working on this PR that you cannot
create a `paymentIntent` on stripe that is < 0.5$. So, you can't create
an OTP for a "free" product. We add safeguards to protect against that.
Also, 0 dollar subscriptions don't create a subscription invoice.
Additionally, the old code relied on being able to fetch the stripe
client secret, which would be null for a 0 dollar subscription so we
create a carve out.

## Summary by CodeRabbit
* **New Features**
* Better free-product checkout handling: $0 subscriptions return an
empty success response without a payment client secret; non-free
subscriptions include client secret when needed.
* UI: “Make free” flow, “Free · {amount}” with price ID, per-price
checkout error indicators/tooltips, and an alert for products with
invalid prices.
* Client- and server-side Stripe one-time minimum checks.
* **Bug Fixes**
* Included-item dialog now resets form state when opened to avoid stale
values.
* **Documentation**
* OpenAPI: clarified client_secret may be omitted when no customer
confirmation is required.
* **Tests**
* Added end-to-end tests covering $0 purchase-session flows.

## Summary
Two related improvements to Stack Auth's AI setup story, both driven by
`packages/stack-shared/src/ai/prompts.ts`:
### 1. Clearer env-var guidance in the cloud-project flow (existing
commit)
The previous wording suggested `STACK_PROJECT_ID` should be prefixed via
a generic _"if available, prefix with your framework's convention"_
comment, and the backend section additionally listed
`NEXT_PUBLIC_STACK_PUBLISHABLE_CLIENT_KEY` — which the SDK does not
actually read in the cloud-project setup. Agents would dutifully
fabricate that third variable.
This is now spelled out:
- The exact prefix per framework (Next.js →
`NEXT_PUBLIC_STACK_PROJECT_ID`, Vite → `VITE_STACK_PROJECT_ID`, etc.) is
given inline.
- A note clarifies that on the client, **only** the project ID is read —
there is no separate publishable / client key.
- A note clarifies that the backend setup reads exactly two variables
(`STACK_PROJECT_ID` + `STACK_SECRET_SERVER_KEY`); a third slot in
`.env.local` is wrong.
### 2. First-class TanStack Start support (new commit)
Until now `mainType: "tanstack-start"` was silently routed through
`@stackframe/react` and inherited the React-only setup steps. Agents had
to guess at the TanStack-specific bits (where to mount `StackProvider`,
what to do with `routeTree.gen.ts`, how `useUser()` behaves under SSR,
where the handler route lives).
`prompts.ts` now:
- Recognizes TanStack Start as its own `mainType` and routes the install
to `@stackframe/tanstack-start`.
- Lists TanStack Start alongside Next.js / React in the
supported-frameworks list and the package table.
- Adds three TanStack-specific steps that don't apply to vanilla React:
1. Mount `StackProvider` / `StackTheme` inside the root route's
`component` (the inner React tree), keeping `shellComponent` as the
document shell.
2. Wrap `<Outlet />` in `Suspense` inside `RootComponent`.
3. Register the Stack handler splat at `src/routes/handler/\$.tsx` with
`ssr: false`.
- Surfaces the two notes that aren't obvious from the React docs:
`routeTree.gen.ts` is generated and shouldn't be hand-edited, and
`useUser()` resolves the SSR user from TanStack Start's request cookies
for free as long as `tokenStore: \"cookie\"` is set.
The auto-generated outputs
(`docs-mintlify/guides/getting-started/setup.mdx`,
`docs-mintlify/snippets/home-prompt-island.jsx`) are regenerated from
the prompt.
### 3. tanstack-start-demo SSR-vs-client examples
Two paired routes (`/ssr` and `/client`) render the same `AuthDemoCard`
so the SSR-vs-\`ssr: false\` tradeoff is observable side-by-side. The
new \`AuthDemoCard\` shows the resolved Stack Auth user (or sign-in/up
buttons) plus the snippet that produced it. The
\`ClientMountedUserButton\` workaround in the header is dropped now that
SSR cookie reading just works, and the empty \`Suspense
fallback={null}\` in \`__root.tsx\` is replaced with a
\`RouteLoadingState\` skeleton.
## Test plan
- [ ] \`pnpm typecheck\` and \`pnpm lint\` both pass on the touched
packages (\`stack-shared\`, \`tanstack-start-demo\`).
- [ ] \`docs-mintlify/guides/getting-started/setup.mdx\` and
\`docs-mintlify/snippets/home-prompt-island.jsx\` are byte-identical to
a fresh \`scripts/generate-setup-prompt-docs.ts\` run.
- [ ] In \`tanstack-start-demo\`, \`/ssr\` renders the user card during
the server response (no flash from signed-out → signed-in), and
\`/client\` renders the empty card on first paint, then resolves to the
user after hydration.
- [ ] \`/handler/sign-in\`, \`/handler/sign-up\`, OAuth callbacks, and
password reset all render correctly through the new splat route.
- [ ] Following the new TanStack Start prompt steps from scratch in an
empty \`npm create @tanstack/start@latest\` project produces a working
sign-in flow without any extra changes.

body on every invocation
- Adds an `/SKILL.md` route on the MCP app that renders the full skill
(CLI usage + docs sidebar generated from `docs.json`)
- Expands `docs-mintlify/guides/getting-started/ai-integration.mdx` with
three install paths (CLI, Skill, MCP) and per-agent config snippets
- Updates `packages/stack-shared/src/helpers/init-prompt.ts` to install
both the MCP server and skill file, with per-project vs global scope
detection
## Test plan
- [ ] `pnpm typecheck`
- [ ] `pnpm lint`
- [ ] Hit the MCP app's `/SKILL.md` endpoint locally and verify it
returns valid markdown with the full docs sidebar
- [ ] Render the updated `ai-integration.mdx` in Mintlify preview and
confirm tabs/cards render

With the new bulldozer rework we dont support default products anymore.
Users are encouraged to currently manually handle granting products to
their end users.
We block api requests and new product creations that attempt to set no
price, and we remove any options to set include-by-default. We also
migrate users' existing product snapshots in `Subscriptions`,
`OneTimePurchases`, and `ProductVersions` to have no price set if it's
an include-by-default product. This will make it so that next time a
user goes onto their products page, they will be informed that the
pricing is invalid and it is no longer delivered by default.
Note, however, that these products will still be providing items and the
like to the users who have them.
<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->
## Summary by CodeRabbit
* **Bug Fixes**
* Migrated legacy product snapshots so missing included-items no longer
break readers.
* Removed deprecated "include-by-default" pricing sentinel; pricing now
requires explicit price entries and write validation rejects the old
sentinel.
* **Chores**
* Simplified dashboard pricing flows: create/edit/save now use explicit
prices and surface an alert when a formerly implicit free plan needs an
explicit $0 price.
* Config overrides and stored data are auto-normalized to explicit price
objects.
* **Tests**
* Updated and added tests covering migration, validation, and switching
behavior for explicit prices.

## Summary
Refreshes the docs around Stack Auth setup, CLI workflows, local
development, the local emulator, known SDK errors, self-hosting, and the
public showcase. This also wires the new docs into Mintlify navigation
and normalizes `sharp` dependency resolution for docs/image tooling.
Base: `dev` -> Head: `docs-mintlify/updates`
Scope: 17 files, +1154 / -435
## What's New
- Adds a dedicated **Stack CLI** guide covering install, auth, init
modes, project commands, config pull/push, `stack exec`, and emulator
commands.
- Adds a full **Local Emulator** guide for QEMU requirements, ports,
default credentials, config-file backed projects, image pulls, state,
and troubleshooting.
- Reworks **Local Development** around two supported workflows:
cloud-backed local dev and emulator-backed local dev, including app env
vars, local config files, CI usage, and common failure modes.
- Rewrites **Self-host** around the supported `stackauth/server` Docker
deployment path, including Postgres, ClickHouse, cron scheduling, seeded
admin access, reverse proxy setup, SDK env vars, email, webhooks, S3
storage, upgrades, and common issues.
- Adds a **Known Errors** reference for public SDK-exposed known errors,
runtime `errorCode` values, and REST API handling.
- Clarifies **CLI App Authentication** so users can distinguish
authenticating their own CLI app from using the official `stack`
command.
- Updates the JWT guide to remove the missing inline viewer reference
and recommend an external JWT viewer.
- Adds showcase cards for Browser Use and Overworld with supporting
images and styles.
- Pins `sharp` to `0.34.5` through pnpm overrides and lockfile cleanup.
## Review Notes
- The self-host guide was audited against the current Docker entrypoint,
server env templates, seed script, ClickHouse migration behavior, cron
endpoints, and SDK API URL env resolution.
- The Docker image starts the backend and dashboard, but not production
schedulers, so the new cron section is called out explicitly.
- Managed Domain email setup is documented as operator-managed because
it depends on server-side Resend/DNSimple credentials; self-hosters are
directed toward Custom SMTP or their own Resend API key.
- `self-host-old.mdx` is kept as a legacy reference file and is not
added to navigation.
- `emulator run` documentation now matches CLI behavior: it stops the
emulator only when it started that emulator instance.
## Test Plan
- [x] Reviewed all files changed by `origin/dev...HEAD`.
- [x] Ran `git diff --check origin/dev...HEAD`.
- [x] Checked IDE diagnostics for the changed docs/CLI files.
- [ ] Preview Mintlify docs locally and click through new navigation
entries.
- [ ] Verify showcase cards and images in light and dark themes.
- [ ] Smoke-test the copied self-host commands in a non-production
Docker environment.

## Summary
- The CLI auth-attempt schema in
`apps/backend/src/app/api/latest/auth/cli/route.tsx` changed
`expires_in_millis.default` from 7,200,000 (2hr) to 120,000 (2min), but
the checked-in OpenAPI JSONs in `docs-mintlify/openapi/` were never
regenerated.
- This causes `lint_and_build` to fail on `dev` (and on every PR
branched off `dev`) because CI runs the codegen and then errors on the
resulting uncommitted diff.
## Changes
- Regenerated `admin.json`, `client.json`, `server.json` via `pnpm
--filter=@stackframe/backend codegen-docs`.
## Test plan
- [ ] CI's `lint_and_build` passes on this PR.
<!-- This is an auto-generated comment: release notes by coderabbit.ai

## Summary by CodeRabbit
* **Documentation**
* Updated CLI authentication token default expiration time from 2 hours
to 2 minutes across API specifications.
<!-- end of auto-generated comment: release notes by coderabbit.ai -->
## Summary
- Adds the generated `@stackframe/tanstack-start` workspace package
registration.
- Adds TanStack Start platform macros/dependencies to the SDK template
and generator.
- Adds TanStack Start cookie/token-store support plus the handler SSR
guard needed by Start.
## Scope
This intentionally excludes Dashboard V2 routes, hooks, components, app
shell logic, and dashboard API type additions. Those stay in the
existing dashboard PR/branch.
## Validation
- `pnpm install --lockfile-only --ignore-scripts`
- `pnpm install --ignore-scripts`
- `pnpm -C packages/template lint
src/components-page/stack-handler-client.tsx src/lib/cookie.ts
src/lib/stack-app/apps/implementations/client-app-impl.ts`
Package typecheck was attempted with `pnpm -C packages/template
typecheck`, but the clean worktree lacks generated package declaration
outputs for workspace dependencies such as `@stackframe/stack-shared`
and `@stackframe/stack-ui`. Per repo instructions, package
builds/codegen are not run by agents.

## Summary by CodeRabbit
* **New Features**
* TanStack Start integration: published SDK package, example demo app,
dashboard onboarding flow, framework-aware CTAs/docs, and a
TanStack-specific provider for client-only auth routes.
* Improved client/server auth: safer runtime guards and consistent
cookie/token-store behavior across SSR and client.
* **Documentation**
* New Integrations guide and expanded getting-started/setup docs with
TanStack Start examples and env/key guidance.
* **Chores**
* Template, build, tooling, and demo config updates to support the new
platform.

## Summary
Splits the Stack Auth MCP server out of `apps/backend` and into a
dedicated Next.js app at `apps/mcp/`, served on port `:42` (suffixed via
`NEXT_PUBLIC_STACK_PORT_PREFIX`) and exposed in production at
`https://mcp.stack-auth.com/mcp`. The backend no longer carries the MCP
transport route; clients now point at the new host.
Base: `dev` → Head: `chore/move-mcp-to-a-sep-app`
Scope: 34 files, +1425 / −353
## What changed
- **New app** `apps/mcp/` — standalone Next.js + `@vercel/mcp-adapter`,
with:
- `src/app/api/internal/[transport]/route.ts` — MCP transport handler
(moved from backend)
- `src/app/mcp/route.ts`, `src/app/route.ts` — public landing + setup
page
- `src/app/health/route.ts` — health check
- `src/mcp-handler.ts`, `src/setup-page.ts`, `src/analytics.ts`
- **Backend** drops
`apps/backend/src/app/api/internal/[transport]/route.ts` (−105) — MCP
code is gone from the backend image.
- **Dashboard** install hint updated to point at
`https://mcp.stack-auth.com/mcp` (was `/`).
- **Dev launchpad** gets an MCP tile so the new service shows up
alongside the rest of the local stack.
- **CI** workflows (`db-migration-backwards-compatibility`,
`e2e-api-tests*`) start the MCP service in the background before running
tests.
- **Docs** (`docs-mintlify`, `docs/`) and `init-stack` / `init-prompt`
updated to reference the new URL.
- **E2E** `apps/e2e/tests/backend/endpoints/api/v1/internal/mcp.test.ts`
reworked to hit the new host; `helpers.ts` and env files gain an MCP
base-URL var.
## Visuals
### New `apps/mcp` setup page (`https://mcp.stack-auth.com/`)
The standalone app's root now serves a self-contained MCP setup guide
with per-client instructions (Cursor, VS Code, Codex, Claude Code,
Claude Desktop, Windsurf, ChatGPT, Gemini CLI):
### Dev launchpad now lists the MCP service
New tile at port suffix `:42`, importance 2, alongside Backend /
Dashboard / Demo app:
## Notes for reviewers
- The MCP transport endpoint moved path: it was mounted under
`/api/internal/[transport]` in the backend; in the new app it's at the
same path but on the dedicated host. The public-facing URL is
`https://mcp.stack-auth.com/mcp`.
- `apps/mcp` ships its own PostHog analytics client (`src/analytics.ts`)
so the backend doesn't have to proxy events for it anymore.
- Port allocation: `${PORT_PREFIX}42` (default `8142` in dev). Picked to
fit the existing dev-launchpad importance-2 row.
- No DB migrations.
## Test plan
- [x] `apps/mcp` builds and `pnpm dev` serves on `:8142`
- [x] Dev launchpad renders the new MCP tile (screenshot above)
- [x] MCP setup page renders client tabs (screenshot above)
- [x] E2E `mcp.test.ts` updated to hit the new host
- [ ] CI green on `e2e-api-tests*` and
`db-migration-backwards-compatibility` workflows (they were touched to
start the MCP service)
- [ ] `init-stack` / `mcp.ts` install flow lands users on the new URL
<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->
## Summary by CodeRabbit
* **New Features**
* Standalone MCP app added with a public /mcp endpoint and health check.
* MCP appears in the dev-launchpad apps list.
* **Documentation**
* MCP endpoint updated to https://mcp.stack-auth.com/mcp in all setup
guides and installer snippets.
