About Database Build
Database Build is an in browser Postgres sandbox with AI assistance, published by Supabase as an experiment. Users can spin up any number of Postgres databases that run entirely inside the browser, and each database is paired with a large language model that helps design schemas, write queries and work with the data through conversation.
It suits developers prototyping a schema, learners exploring SQL and anyone who needs a disposable Postgres instance without installing anything. Useful capabilities include drag and drop CSV import that generates a table on the fly, generated reports that can be exported, generated charts, and database diagrams that show tables and relationships as an editable graph. All queries run locally in the browser through PGlite, a WebAssembly build of Postgres, so there is no remote container or proxy, and data is stored in IndexedDB so changes survive a page refresh. The project also includes a browser proxy that exposes an in browser database over a standard Postgres connection, and a deploy worker that moves a sandbox database to a hosted platform, currently Supabase.
No pricing is published. The site is offered free as a Supabase experiment, and the source code is open under the Apache 2.0 license, so teams can also run their own copy.
The project was originally called postgres.new. Supabase renamed it to database.build so it would not be mistaken for an official Postgres project, while keeping it focused on Postgres.
