About Helicon
Helicon is an unofficial, community-built, MIT-licensed desktop and web app for Meta's Muse Code coding agent. It replaces terminal tab-hopping with one window showing projects grouped by folder (worktrees included), threads, inline diffs, approvals and cost. A local daemon spawns one muse serve host per workspace and talks to it over the Muse Session Protocol via the official @muse-code/sdk, instead of scraping the terminal. Authentication uses your own muse login, credentials are never stored by Helicon, and all state lives in local SQLite. It runs natively on Windows without WSL, plus macOS, Linux and a VS Code panel.
