Supabase Changes Default: New Tables No Longer Automatically Exposed to Data and GraphQL API

Supabase is implementing a significant platform change where new tables in the public schema will no longer be automatically exposed to the Data API and GraphQL API by default. This change, which becomes the default for all new projects starting May 30, 2026, requires developers to explicitly grant privileges for API access. The move aims to enhance security and promote declarative code practices, preventing accidental exposure of unprotected tables.
