Helicon
FreeOpen-source desktop and web app for Meta's Muse Code agent
What is Helicon?
Helicon is a free, MIT-licensed desktop and web interface for Muse Code, Meta's command-line coding agent. It puts every project, session, diff, approval and cost in one window, running on the Muse Code plan you already pay for.
Threads are grouped by project folder and worktree, every edit shows up as an inline diff where it happened, and approval requests for shell commands or edits appear the moment they arrive so nothing is bypassed. Sessions can be resumed in one click.
It runs natively on Windows without WSL, on macOS and on Linux, and also inside VS Code. Credentials stay in Muse Code, local state is kept in SQLite on your machine, and it is an unofficial community project that is not affiliated with Meta.
