A team at Neon developed a browser-based version of the Postgres client, psql, initially conceived during an internal hackathon. This innovative tool utilizes Neon's WebSocket proxy and serverless driver to overcome the limitations of the browser environment, which lacks access to the TCP stack necessary for direct database connections. The app allows users to instantiate a database from a template, generating a unique and isolated connection string almost instantaneously through Neon’s branching feature. The browser app supports SQL queries and slash commands, providing a simplified terminal-like experience without full terminal emulation. The project, which is open-source, invites community feedback and contributions, with potential future enhancements like querying actual databases and AI-powered SQL generation on the horizon.
