Townie is Val Town’s in-browser coding agent. Pretty much anything you can do in the Val Town UI, Townie can do: read, write, and run code; read SQLite, blob storage, logs, and environment variables; schedule crons; view version history, create branches; and more.
Powered by the Claude family and the Val Town MCP server. Available on Pro and Teams plans. Click the little robot in the top right corner on val.town to get started.
