Pick auth by how much you want managed vs. controlled. Clerk is the fastest path for modern React/Next.js with polished UI. Auth0 and WorkOS cover enterprise SSO and complex identity. Supabase Auth shines when you’re already on Supabase Postgres with RLS. Better Auth and Auth.js are open-source if you want to self-host. Kinde adds orgs and RBAC with a generous free tier. Stytch for passwordless-first flows. For full backends (DB + auth + storage), see Backend as a Service too.
