If you want an alternative to Supabase Auth, here are the main options depending on what you need:
Managed Auth services
- Auth0 – very feature-rich, good enterprise options, but can get expensive.
- Clerk – very developer-friendly, great UX for modern web apps.
- Firebase Authentication – easy to use, especially if you're already in the Google/Firebase ecosystem.
- WorkOS – best if you need B2B features like SSO, SCIM, org management.
- Descope – modern auth flows, passkeys, social login, no/low-code friendly.
Open-source / self-hosted
- Keycloak – powerful, widely used, supports SSO/OIDC/SAML, but heavier to manage.
- Ory – flexible, more engineering-heavy, good for custom auth architectures.
- Zitadel – modern open-source IAM platform.
- Auth.js – good if you want to build auth into a Next.js app with many providers.
- Better Auth – newer open-source auth framework, designed for modern JS apps.
If you want a backend-first alternative
- PocketBase – lightweight, includes auth + database, good for small apps/prototypes.
- Nhost – closest to Supabase in concept, with Postgres + GraphQL + auth.
- Appwrite – backend platform with auth, DB, storage, functions.
