Looking for the DeepSeek Harness desktop download? The official app is free on deepseek.com/harness for macOS (Apple Silicon) and Windows (64-bit), and it’s a preview build that installs in a couple of minutes. I walk through the whole install in the video below. Here’s exactly where to download it, what to do on Linux, and the first-run settings that matter.
Key takeaways
- Official download: deepseek.com/harness — macOS (Apple Silicon) and Windows (64-bit).
- It’s a preview build, free and open source.
- Linux: no official desktop yet — use
npx @deepseek-ai/dsh webor a community client. - No separate Node.js install needed for the desktop app.
Where to find the DeepSeek Harness desktop download
Go to deepseek.com/harness. The page lists two desktop downloads — macOS for Apple Silicon and Windows 64-bit — plus the command-line options for everyone else. Avoid third-party “download” sites: the official page and the official GitHub repo are the only sources I’d trust.
| Platform | How to get DeepSeek Harness | Notes |
|---|---|---|
| macOS (Apple Silicon) | Desktop app from deepseek.com/harness | Preview build; bundles its own runtime |
| Windows (64-bit) | Desktop app from deepseek.com/harness | Built-in sandbox with a permission-repair skill |
| Linux | npx @deepseek-ai/dsh web, or a community desktop client | No official Linux desktop download listed yet |
| Any platform | npx @deepseek-ai/dsh web or clone the GitHub repo | Opens the web UI at 127.0.0.1:3080 |
Installing after the DeepSeek Harness desktop download
- Mac: open the download and drag the app to Applications, then launch it. Allow microphone access if you want voice input.
- Windows: run the installer and launch from the Start menu. If Windows reserves the default port, v0.2.1 now lets the system assign one automatically.
- First run: add a model provider, choose a project folder, pick a mode, and enable the plugins you want.
The desktop app bundles its own runtime and a dsh command for plugins, managed from the menu bar, so you don’t need Node or pnpm. That’s a big improvement on v0.1.

If there’s no download for your system
On Linux, run npx @deepseek-ai/dsh web (needs Node) and open the web UI at 127.0.0.1:3080, or clone the repo from GitHub. Community desktop clients exist too — see my Linux guide. On an Intel Mac, check the download page for your options; the v0.2 release notes include a fix for the Intel build’s bundled runtime.
Before you start, dated 5 October 2026: DeepSeek Harness is open source (MIT) but built by a Chinese company, so I don’t put private client data or anything sensitive into it. The desktop app is labelled a preview, and features move weekly — check the release notes for the current state.
The bottom line on the DeepSeek Harness desktop download
The DeepSeek Harness desktop download is free from deepseek.com/harness for Mac (Apple Silicon) and Windows 64-bit, installs in minutes, and needs no Node. Linux users use the npm command or a community client. Download it from the official page only, add a free model, and you’re running.
What I’d set up first
- A free model through OpenCode or OpenRouter, so testing costs nothing.
- Creator mode, so you can customise plugins as you go.
- One scheduled task — a weekly report or deck — to see automation working.
- Voice input, if you like talking through tasks.
After the DeepSeek Harness desktop download: your first session
Once the app is installed, this is the quick-start workflow I use:
- Start a new session and pick the project folder you want to work in.
- Choose a mode — Creator if you want to customise, Standard for normal coding.
- Confirm your model in the session header.
- Click the plus button to open extra chats and run agents in parallel.
- Rename projects and sessions so your history stays organised.
Then connect a model provider. Here are the three I use:
| Provider | Why use it |
|---|---|
| OpenCode | Free custom models with just an API key — my go-to for zero-cost coding |
| OpenRouter | A wide catalogue, including free models, on one key |
| DeepSeek | DeepSeek’s own models plugged straight in — I ran DeepSeek V4.13 in my test |
v0.2 also made the harness far better with everyday files: it can edit documents, spreadsheets and PDFs, organise information, analyse data, make charts and build slide presentations, with previews of Office files, PDFs, images and Markdown right in the sidebar. That turns it from a coding tool into a general AI worker — I’ve had it build landing pages and decks from the same session.
