DeepSeek Harness

English | 中文

DeepSeek Harness ( dsh ) is an open-source agent harness developed by DeepSeek AI .

It uses an architecture where everything is a plugin , and is powered by Cordis , whose design is described in A Programming Paradigm for Spatiotemporal Composability .

Developer preview

DeepSeek Harness is currently in developer preview and is iterating rapidly. THERE WILL BE COMPATIBILITY-BREAKING CHANGES.

Run

Run from npm

Install Node.js , then run:

npx @deepseek-ai/dsh web

The command starts the Web UI at http://127.0.0.1:3080 by default and opens it in the default browser for a local launch. An SSH launch only prints the host URL because the SSH client or editor owns the local forwarded address.

Pass --no-open to run the server without opening a browser. See Web UI guide .

Run from source

To run from a repository checkout:

git clone https://github.com/deepseek-ai/deepseek-harness.git

cd deepseek-harness

pnpm install

pnpm run build

pnpm dsh web

pnpm run build prepares the repository artifacts. pnpm dsh web uses those built artifacts without rebuilding.
