DeepSeek opened the Harness repo on 13 August 2026. The official one-liner is:

npx @deepseek-ai/dsh web

You need Node.js. The UI binds to http://127.0.0.1:3080.

From source: clone deepseek-ai/deepseek-harness, then pnpm install && pnpm run build && pnpm dsh web.

v0.1 is a developer preview. There is no official TUI. Bring your own DeepSeek API key. Full notes: Install.
