Having trouble? Check the answers below.

How do I start the Web UI?

One command: npx @deepseek-ai/dsh web. It prints the address — by default http://127.0.0.1:3080. See the quick start for more.

Is there a hosted online version? Can I skip npx?

There is no cloud-hosted online version. The web version (Web UI) starts on your machine with npx @deepseek-ai/dsh web — open http://127.0.0.1:3080 in a browser; or grab the Windows / macOS desktop clients at the top of this page, no command line needed. Project files, API keys, and sessions stay local. If startup hangs, see troubleshooting.

How do I build from source?

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

How do I configure a model?

Open Settings → Models in the Web UI, enter your DeepSeek API key and save. Model routing works immediately — no restart needed. See using the Web UI.

How many run modes are there?

Four: Standard, PTC (programmatic tool calling), Minimal (just a shell and a file-editing tool), and Creative (try plugins in memory and author new modes). See architecture.

What capabilities are plugin-based?

Model, tools, skills, sessions, sandbox, storage, loops, scheduling, and UI are all composed from plugins. See developing plugins.

How do I join the community?

Share feedback or bug reports via GitHub Discussions, and add the dsh-plugin topic to your plugin repository. See contact.
