Start at the top and work your way down, or jump straight to the section you need.
First-time setup, install the SDK, get auth running in minutes.
Open app guides from a home-screen style quick access grid, modeled after dashboard Overview.
Configure Stack App deeply, integrate your backend, and use lower-level interfaces where needed.
Use hooks, objects, and types to read and write auth data directly in your app code.
Integrate Stack Auth from any backend or language through HTTP endpoints and webhook flows.
Reach for product access, source code, and support channels when you need more than reference docs.
