Supabase Auth ships with over 20 built-in social providers: Google, GitHub, Apple, and more. But what about your company's SAML-to-OIDC bridge? A regional identity provider required for compliance? Your self-hosted GitHub Enterprise? Until now, if your identity provider wasn't on the built-in list, you were stuck.
Today we're launching Custom OIDC Providers, letting you connect any standards-compliant OpenID Connect identity provider to your Supabase project. Once configured, custom providers work just like built-in ones: same sign-in flow, same client libraries, same RLS enforcement.
Built-in providers cover the most common cases, but not every identity provider fits neatly into that list:
Regional compliance: Government or industry-specific providers mandated in certain regions.
Self-hosted providers: GitHub Enterprise Server, GitLab self-managed, or any on-premise OAuth2 service.
