What is it?

Helicon is a desktop client and VS Code extension for Meta's Muse Code CLI (`muse`), which otherwise runs only in the terminal. It groups sessions by project directory, keeps full history with resume, and shows file changes as inline diffs. Tool approvals are surfaced to the user rather than auto-accepted.

The desktop app is built with Tauri 2 on Windows, macOS and Linux, and shares one React UI with a web client that can connect to a remote daemon. A Node daemon spawns `muse serve` per workspace and talks to it over the Muse Session Protocol through the official SDK. On Windows it can run Muse Code natively or inside WSL2 with path translation.

Helicon uses the user's own `muse login` and does not store credentials of its own. Session state is kept in a local SQLite database. The project is MIT-licensed and is unofficial, not affiliated with Meta.

Things to know

  • Unofficial community project, not made or endorsed by Meta.
  • Requires a Muse Code plan or pay-as-you-go billing and the muse CLI installed and signed in.
  • Windows and macOS builds are not code signed or notarized yet, so the OS will show security warnings.
  • Requires an installed muse CLI; the Linux AppImage needs FUSE on some distributions.
