Muse Code Desktop

A native desktop command center for the Muse Code CLI. Muse Code Desktop brings sessions, approvals, reasoning controls, changed files, and agent activity into one focused interface while keeping the official Muse CLI as the execution engine.

[!IMPORTANT]
Muse Code Desktop is an independent open-source project and is not affiliated with Meta. It requires the official muse CLI and an active Muse Code subscription or API key.

Highlights

• Organize workspaces, sessions, and archived threads from one sidebar.
• Follow streaming agent activity, plans, tool calls, approvals, and background work.
• Choose models, reasoning effort, and approval behavior from the composer.
• Attach files and images with the native picker or drag and drop.
• Review changed files and unified diffs without leaving the conversation.
• Use light and dark themes with seven accent palettes.
• Keep API keys in the operating system credential store.
• Run on the native operating system webview through Tauri 2.
