Stack is an open-source, self-hostable, highly customizable authentication and user management system. We provide frontend and backend libraries for Next.js, React, and JavaScript. 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 and is funded (among others) by Y Combinator and Guillermo Rauch. Check out our GitHub: https://github.com/stack-auth/stack
Building the best user login/management experience for developers, 100% open-source!
I build user authentication @ Stack. If you're building a modern web app with user logins, we should chat! https://n2d4.github.io 👋

Hi all! We're Zai and Konsti, and we’re repeat founders who believe that devtools must be dev-friendly.
User authentication sucks. Existing solutions are a pain to set up and have hostile pricing, terrible documentation, and vendor lock-in. The few good solutions that exist only do authentication and don't even touch authorization or user management.
Stack Auth was born out of years of frustration. We wanted to build something better.
If you're building B2B software, we'll deal with organizations, permissions, and RBAC for you.
If you're building a Next.js app, we have React components for sign-in, password reset flows, and all sorts of things like account settings and teams. And they're customizable.
