The easiest, most secure way to use WireGuard and 2FA.

Adds two Gokrazy-based vmtests covering the tailscaled web client at
port 5252:
* TestWebClientLocalAccess enables the web client on a single node
and exercises the canonical owner session flow against the node's
own Tailscale IP: an unauthenticated GET /api/auth that identifies
the caller, a GET /api/auth/session/new that issues a
TS-Web-Session cookie, and a final GET /api/auth that reports
authorized=true with the cookie.
* TestWebClientRemoteAccess runs the same session flow from a peer
node on the same tailnet against a second target node's web
client, exercising netstack interception of incoming :5252
traffic, cross-node WhoIs, and the same-user "owner" path. It
then flips the test control server's AllNodesSameUser off,
re-logs in the client under a fresh identity, and asserts that
GET /api/auth/session/new returns 401 with body "not-owner" --
exercising the cross-user rejection in client/web/auth.go.
To make the natlab test environment exercise the same code path
as production (check mode, where the web client posts to
/machine/webclient/init via Noise and waits on a control-issued
auth URL), this also:
* Allowlists the natlab fake control hostname "control.tailscale"
in client/web/auth.go's controlSupportsCheckMode so the web
client follows the check-mode branch rather than the
no-check-mode shortcut that immediately marks new sessions
authenticated.
* Adds /machine/webclient/{init,wait} handlers to testcontrol.
init returns a placeholder auth ID and URL; wait returns
Complete=true immediately, so the web client's awaitUserAuth
resolves on its first call. Together these let the tests drive
the full check-mode session lifecycle without a real
browser-click loop.
To support the multi-request HTTP flows from the test harness,
this also adds:
* vmtest.Env.HTTPGetStatus, a sister of HTTPGet that returns the
upstream status code, body, and Set-Cookie cookies (as a
vmtest.HTTPResponse) and accepts cookies on the outgoing
request, so tests can drive flows that depend on cookie
continuity.
* Cookie pass-through in cmd/tta's /http-get handler: it forwards
the Cookie request header upstream and surfaces upstream
Set-Cookie response headers downstream. This is what lets
HTTPGetStatus carry a session cookie across requests.
Previously the only tests of the web client were in-process
httptest-based handler tests in client/web/web_test.go; nothing
exercised the actual port 5252 listener wiring, the cross-node
auth path, cookie-driven session state transitions through the
check-mode control round-trip, or the not-owner rejection end
to end.

Tailscale
Private WireGuard® networks made easy
Overview
This repository contains the majority of Tailscale's open source code.
Notably, it includes the tailscaled daemon and
the tailscale CLI tool. The tailscaled daemon runs on Linux, Windows,
macOS, and to varying degrees
on FreeBSD and OpenBSD. The Tailscale iOS and Android apps use this repo's
code, but this repo doesn't contain the mobile GUI code.
Other Tailscale repos of note:
- the Android app is at https://github.com/tailscale/tailscale-android
- the Synology package is at https://github.com/tailscale/tailscale-synology
- the QNAP package is at https://github.com/tailscale/tailscale-qpkg
- the Chocolatey packaging is at https://github.com/tailscale/tailscale-chocolatey
For background on which parts of Tailscale are open source and why, see https://tailscale.com/opensource/.
Using
We serve packages for a variety of distros and platforms at https://pkgs.tailscale.com.
Other clients
The macOS, iOS, and Windows clients use the code in this repository but additionally include small GUI wrappers. The GUI wrappers on non-open source platforms are themselves not open source.
Building
We always require the latest Go release, currently Go 1.26. (While we build releases with our Go fork, its use is not required.)
go install tailscale.com/cmd/tailscale{,d}
If you're packaging Tailscale for distribution, use build_dist.sh
instead, to burn commit IDs and version info into the binaries:
./build_dist.sh tailscale.com/cmd/tailscale
./build_dist.sh tailscale.com/cmd/tailscaled
If your distro has conventions that preclude the use of
build_dist.sh, please do the equivalent of what it does in your
distro's way, so that bug reports contain useful version information.
Bugs
Please file any issues about this code or the hosted service on the issue tracker.
Contributing
PRs welcome! But please file bugs. Commit messages should reference bugs.
We require Developer Certificate of
Origin
Signed-off-by lines in commits.
See commit-messages.md (or skim git log) for our commit message style.
