What is Postgres Runner?

Postgres Runner is a zero-setup, in-browser PostgreSQL 16 playground powered by WebAssembly (WASM). It runs authentic PostgreSQL directly on your device without sending SQL or data to an external server.

Is my data stored in the cloud or private?

Your queries and tables are 100% private and execute entirely within your browser using client-side WebAssembly and IndexedDB persistent storage. No database servers or tracking are involved.

Does it support PostgreSQL 16 features?

Yes! Postgres Runner supports PostgreSQL 16 syntax and features including CTEs (Common Table Expressions), Window Functions, JSONB operators, Generated Columns, ON CONFLICT upserts, and Foreign Keys.
