   DeepSeekGUI – A Windows desktop client for DeepSeek's coding agent▲5

   Hi HN, I built a desktop client for DeepSeek Harness (DeepSeek's open-source coding agent). V1 wraps the official Harness Web UI in an Electron shell with some desktop additions — installer, system tray, built-in browser panel (visible Edge, so you can watch the agent browse), and a sandboxed terminal. One-click install, just need an API key. V2 is in development — replacing the upstream Web UI with a custom workbench built for desktop. Source available under PolyForm Perimeter. Would love feedback on what you'd want from a desktop coding agent client.
