psql from the browser

The psql browser app was developed by Neon as a result of an internal hackathon idea. The project aimed to run the popular Postgres database client, psql, in a browser environment, overcoming technical limitations such as TCP stack access. A WebSocket proxy and serverless driver were used to connect to databases directly from browser-like environments, allowing users to instantiate a database with existing data and execute SQL queries against it. The app features instant connection setup, unique and isolated connections, slash commands for schema inspection, terminal emulation of the psql session, and is open-source, inviting user feedback and contributions.
