FAQ
Frequently asked questions about Stack
Languages & Frameworks
What languages are supported?
In the frontend, Stack supports TypeScript and JavaScript with Next.js. In the backend, 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?
While you can use any backend framework with Stack, the frontend is tightly integrated with Next.js. If you want to use a different frontend framework, you will have to build the integration ourselves with the client endpoints of our REST API. Some members of our community have started projects to do this, so you may want to join our Discord to coordinate with them.
Can I use Stack with the Next.js pages router?
Only the Next.js app router is currently supported. However, just like any other unsupported framework, you can use the client endpoints of our REST API to build your own integration.
