FAQ

Languages & Frameworks

What languages are supported?

For frontends, Stack supports TypeScript and JavaScript. For backends, Stack has a flexible REST API that can be used with any language or framework.

Can I use Stack with other JavaScript frameworks, like Astro or Angular?

Yes! You can use our vanilla JavaScript SDK, or, if the framework is React-based, our React SDK.

Can I use Stack with the Next.js pages router?

Only the Next.js app router is currently officially supported, although some members of the community have successfully used the React or vanilla JavaScript SDKs with the pages router.

How do you compare to `<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>.

Can I migrate my existing userbase to Stack Auth?

Yes! You can create users programmatically using our REST API.
