About
Stack is the open-source authN, authZ, and user management platform. We build for devs who want to iterate quickly, offering both managed auth and self-hosting. You can set it up in one minute and scale with the project as it grows. Stack was built by repeat founders with strong technical backgrounds. Check out our GitHub: https://github.com/stack-auth/stack
