About this tool

Helicon is a free, MIT-licensed desktop app (Windows, macOS, Linux) and VS Code extension for Meta's Muse Code CLI. It drives the muse command you already have: no API key, no second bill.

Threads from every project sit in one sidebar, edits show as inline diffs where they happened, approvals come one at a time, and workflows, side chats and SSH projects are built in. A usage page prices each thread at published API rates.
