TypescriptConnect to your PostgreSQL database with a connection string and get a live ER diagram with foreign key relationships. Attach permanent notes and tags to any table or column — stored on your own server, never uploaded anywhere. Built for developers who inherited an undocumented schema, or teams who can't send their production database to a third-party cloud tool. One-time purchase, MIT licensed, self-hosted.
