Stack Auth is the open-source Auth0 alternative. We build log-in and signup pages, and all the shenanigans that come with that — such as authorization and user management.

We are right on the intersection of developer experience and design. Our philosophy is that devtools aren't intuitive enough; we want to build apps that are both powerful and elegant. In the team, we spend a lot of time talking about programming languages, databases, and scale; if you enjoy nerding out about any of those, you should totally join us.

Open-source is a core value of ours. We strongly believe that open-source will win the auth market, just like it won over databases; and we also strongly believe that we are the best open-source auth platform out there.
