Stack Auth

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.
