What is Supabase?
Supabase is a development platform where every project is a full Postgres database, extended with Authentication, instant REST Data APIs, Edge Functions, Realtime data sync, file Storage and Vector embeddings. The page positions it as a backend for production applications that can be built quickly and scaled to millions of users.
In practice you create a project, define tables in the Table Editor or with SQL, and secure data with Row Level Security policies. Sign-up and login are built in, and the REST APIs are generated from your schema, so frontend code such as React can query data with a short client library call. You can also deploy custom server code as Edge Functions, store large files, push live updates to multiplayer or collaborative interfaces, and store and search vector embeddings for ML models such as OpenAI or Hugging Face. Ready-made starter templates for Next.js, Flutter, Expo and LangChain are provided.
