>log in to commentHey everyone 👋 I'm Harjot, the maker. I use Meta's Muse Code every day, and keeping one terminal per project got messy fast: I lost track of which session was waiting on me, what it changed, and what it was costing. So I built Helicon, a desktop app that sits on top of the muse CLI you already have. - Every project and thread in one sidebar - Edits as inline diffs where they happened, with keep/undo - Approvals one at a time, with the exact command shown - A usage page that prices each thread at API rates, plus your 5-hour and weekly limits - Also ships as a VS Code extension (works in Cursor, Windsurf and Antigravity) It's MIT-licensed and free. You can try it in the browser at helicon.sh/try without installing anything. I'd love feedback, especially on what's missing from your Muse Code workflow. (Unofficial community project, not affiliated with Meta.)
- Free, open‑source desktop and web app
- All projects, sessions and diffs in one window
- Inline diffs appear right where they happen
- Projects grouped by folder with worktrees
- Local state stored in SQLite on your machine

- Helicon vs Cursor: Cursor is an AI-powered code editor, while Helicon is a GUI for the Muse Code CLI only.
- Helicon vs Cline: Cline provides an autonomous coding agent inside IDEs, whereas Helicon visualizes Muse Code sessions.
- Helicon vs Aider: Aider is a terminal-based AI pair programmer; Helicon offers a graphical interface for the same Muse Code backend.
- Helicon vs OpenAI Codex: OpenAI Codex is a separate coding agent platform; Helicon is a client for Meta’s Muse Code, not OpenAI.
