What they do

Problem

Developers need a fast, flexible alternative to proprietary identity platforms for authentication, authorization, and user management that can be managed or self-hosted.

Solution

Stack Auth provides an open-source authN/authZ and user management platform that can be set up quickly and run as a managed service or self-hosted.

Who it's for

Software developers and teams building applications who want quick iteration with managed auth or self-hosting.
