Overview
Supabase Auth is the authentication component of the open-source Supabase backend platform, offering sign-in, social login, and tight integration with Postgres row-level security.
Capability deep-dive
Integration with the Supabase database and developer experience are the strengths, especially for startups building on Postgres. It is part of a backend platform rather than a standalone IdP, so its value is highest within Supabase.
Pricing
Open-source free; bundled in Supabase plans.
Bottom line
A natural auth layer for teams building on Supabase, not a standalone enterprise IdP.
