description: >-
  Stack Auth is an open-source authentication and user management platform
  positioned as a self-hostable alternative to closed-source providers like
  Clerk and Auth0. It bundles password, OAuth / SSO, and two-factor sign-in
  flows with organizations, teams, role-based access control, impersonation,
  webhooks, and pre-built UI components built on shadcn/ui (or a headless
  SDK). Stack Auth is available as a hosted SaaS at app.stack-auth.com and as
  a self-hosted deployment from the stack-auth/stack monorepo on GitHub.
  Authentication is JWT-based. Y Combinator-backed.
