The desktop app is built on Tauri and bundles its own Node runtime — download and run. A China mirror is used where available; releases not on the mirror fall back to GitHub.
These builds are not code-signed yet, so the first launch is blocked: on macOS open System Settings › Privacy & Security and click “Open Anyway”; on Windows click More info › Run anyway at the SmartScreen prompt. On Linux, chmod +x the AppImage first.
