Stack Auth
The open-source Auth0 & Clerk alternative for auth in minutes

Stack Auth is an open-source authentication and user management platform designed as an alternative to Auth0 and Clerk. It provides pre-built UI components, headless SDK options, REST APIs, OAuth integrations, RBAC, organizations and teams management, and webhook support. Developers can integrate login, signup, and user management into their apps quickly without handling JWTs or OAuth flows manually.
