Install DeepSeek Harness (dsh)

Two ways to run DeepSeek Harness: the one-command npm install, or building from source. Based on the official documentation.

Before you start

  • You need Node.js installed.
  • DeepSeek Harness is in developer preview — it's iterating fast and breaking changes will come.

Option 1 — Install & run from npm

Run the Web UI with a single command:

npx @deepseek-ai/dsh web

This starts the Web UI at http://127.0.0.1:3080.

Option 2 — Build & run from source

Clone the repository and build it locally:

git clone https://github.com/deepseek-ai/deepseek-harness.git
cd deepseek-harness
pnpm install
pnpm run build
pnpm dsh web

Uses pnpm — install it if you don't have it (npm install -g pnpm).

What to do next

  1. Open the Web UI and follow the tutorial to configure a model and run your first task.
  2. Add your DeepSeek API key under Settings → Models.
  3. Build your own plugins with the plugin guide.
