Stack Auth: Open-source Clerk/Auth0 alternative

Stack Auth is a managed user authentication solution. It is developer-friendly and fully open-source (licensed under MIT and AGPL).

Stack Auth gets you started in just five minutes, after which you'll be ready to use all of its features as you grow your project. Our managed service is completely optional and you can export your user data and self-host, for free, at any time.

We support Next.js, React, and JavaScript frontends, along with any backend that can use our REST API. Check out our setup guide to get started.

How is this different from X?

Ask yourself about X:

• Is X open-source?
• Is X developer-friendly, well-documented, and lets you get started in minutes?
• Besides authentication, does X also do authorization and user management (see feature list below)?

If you answered "no" to any of these questions, then that's how Stack Auth is different from X.

and Authentication components that support OAuth, password credentials, and magic links, with shared development keys to make setup faster. All components support dark/light modes.
Idiomatic Next.js APIs We build on server components, React hooks, and route handlers.
User dashboard Dashboard to filter, analyze, and edit users. Replaces the first internal tool you would have to build.
Account settings Lets users update their profile, verify their e-mail, or change their password. No setup required.
Multi-tenancy & teams Manage B2B customers with an organization structure that makes sense and scales to millions.
Role-based access control Define an arbitrary permission graph and assign it to users. Organizations can create org-specific roles.
OAuth Connections Beyond login, Stack Auth can also manage access tokens for third-party APIs, such as Outlook and Google Calendar. It handles refreshing tokens and controlling scope, making access tokens accessible via a single function call.
Passkeys Support for passwordless authentication using passkeys, allowing users to sign in securely with biometrics or security keys across all their devices.
Impersonation Impersonate users for debugging and support, logging into their account as if you were them.
Webhooks Get notified when users use your product, built on Svix.
Automatic emails Send customizable emails on triggers such as sign-up, password reset, and email verification, editable with a WYSIWYG editor.
User session & JWT handling Stack Auth manages refresh and access tokens, JWTs, and cookies, resulting in the best performance at no implementation cost.
M2M authentication Use short-lived access tokens to authenticate your machines to other machines.
