Why PostgreSQL?

PostgreSQL is an advanced open-source relational database with over 35 years of history. It combines SQL reliability with JSON flexibility. It is the foundation of Supabase and our entire backend stack. When your data must be safe and always available, PostgreSQL is the only choice.

What PostgreSQL gives you

  • ACID reliability

    Full ACID compliance. Your data stays safe even during server failures or connection drops.

  • JSON + SQL

    Relational tables and JSON documents in one database. Structured queries and flexible data together.

  • Extensions

  • Performance at scale

    Advanced query planner, parallel queries, partitioning. Handles millions of rows without performance loss.
