Supabase is an open-source backend platform that provides a managed Postgres database with built-in authentication, real-time capabilities, and REST APIs. Developers use it to quickly build web, mobile, and AI applications without managing database infrastructure themselves, with support for vector embeddings, geospatial queries, and real-time data synchronization. It serves as a self-hosted or managed alternative to Firebase, offering the flexibility of Postgres while reducing boilerplate backend code.
