Stack Auth
Open-source auth & user management for developers
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

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.
Other features include:
- 100% open-source and self-hostable, though we also provide a Cloud service
- User dashboard to view, modify, and understand your users
- Multi-tenancy for your business customers
- Access token management for APIs of OAuth services that users connect with
- Impersonation to log in as one of your own customers for debugging and live support
- Webhooks to sync your data with other systems like databases or Slack
- Customizable e-mails on triggers such as user sign-up
- Flexible REST API for use with any backend
