Hey PH — built this because I kept running into the same wall: tools that ask for an account before you can do anything useful.
zerodatatools is the opposite. Everything runs in your browser. Paste your CSV, write your prompt, scaffold your MCP server — nothing touches a server.
Three tools live today. Happy to answer questions about the architecture or the zero-data approach. What would you build next?
