Open-source desktop GUI for Meta's Muse Code coding agent: threads, diffs, approvals and cost.
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. Try it at helicon.sh/try. Unofficial, not affiliated with Meta.
