MongoDB's Data API has reached its end-of-life and will be deprecated by September 30, 2025. This has led to a need for engineering teams to evaluate alternatives, with Supabase emerging as a suitable replacement due to its built-in support for REST APIs via PostgREST, mirroring the core functionality previously provided by MongoDB's Data API. The transition from MongoDB to Supabase requires substantial refactoring, but offers a simplified path through automatic generation of REST APIs and real-time capabilities, authentication, file storage, and serverless functions. Engineering teams can leverage Supabase's Data API as a drop-in replacement for MongoDB's deprecated Data API, with features such as authentication, role-based access control, storage, edge functions, and more available once the data is migrated. However, careful planning and methodical execution are necessary to navigate this migration confidently, considering factors such as schema flexibility, complexity in migration, query patterns, and add indexes to optimize performance.
