Auth & Identity
Sign-in, SSO, user management. Browse the 7 parent tools below — each has a dedicated page with up to 10 indie or bootstrapped alternatives, plus pricing, founders, and where applicable, open-source flags.
Auth0 made auth a one-import-statement problem and then pre-IPO-priced itself accordingly. The indie auth space (Clerk, Stytch, WorkOS, Supabase Auth, BetterAuth) has closed the DX gap and undercut on price — and the open-source bets (Ory, SuperTokens) give you escape hatches. The decision usually comes down to: do I want to own user records in my own database or delegate?
What to look for
- Customer-facing UI components you can theme without forking
- First-party support for the SSO standards you'll need (SAML, OIDC)
- Self-hosting option if you can't ship customer data to a third party
- MAU pricing (not per-seat) with a clear tier ladder
Common gotchas
- MFA features paywalled into enterprise tiers
- Per-organization pricing on top of per-user pricing
- Migration tools that are 'soon' — confirm before you commit
Editor's pick
Clerk for SaaS that wants a polished pre-built UI. Supabase Auth if you're already on Supabase. WorkOS for B2B teams that need SAML day one. BetterAuth for the open-source/owned-data crowd.
