A desktop home for DeepSeek Harness

DeepSeek Harness Desktop runs the Harness Web UI as a native macOS application. It starts and monitors the harness process, discovers its port, and loads the interface in a native window. It is a shell—not a fork. A local Harness checkout stays untouched and can continue to follow upstream normally.
DeepSeek Harness Desktop workspace with AI conversation, code editor, file tree, and browser

Conversation, code, files, and a real browser share one native desktop workspace.

DeepSeek Harness Desktop is an unofficial community project by OneTest AI. It is not affiliated with, endorsed by, or supported by DeepSeek.
