DeepSeekGUI is a Windows desktop client for DeepSeek Harness — DeepSeek's open-source coding agent. V1 packages the official Harness Web UI into a native app with desktop integration: one-click installer, built-in browser (visible Edge — watch the agent browse in real time), sandboxed terminal, system tray, and a bilingual interface. Just the installer and a DeepSeek API key. Everything else is bundled. V2 with a fully custom workbench is in active development.
