psql from the browser

Neon has developed a tool to run psql, the popular Postgres command-line client, directly in the browser. This innovation emerged from an internal hackathon and utilizes a WebSocket proxy, allowing seamless connection to databases in browser environments where the TCP stack is inaccessible. The app includes features like database instantiation from templates, SQL query execution, and slash commands for database schema inspection. It also provides a unique, isolated connection string for each session. The project is open-source and available for contributions.
