DeepSeek Harness desktop is the biggest change in the v0.2 update: the open-source agent harness now runs as a proper app on Mac and Windows instead of a terminal plus a browser tab, and it’s completely free. I installed it the day it dropped and walked through everything in the video below — the setup, the plugin library, the new scheduled automation, and how to run it on free models so the whole thing costs nothing.
Key takeaways
- The v0.2 update turns DeepSeek Harness into a free desktop app for macOS and Windows, downloaded from deepseek.com/harness.
- Your previous sessions and projects carry over automatically.
- A built-in plugin manager, agent teams, voice input and scheduled automation tasks come included.
- Plug in free models via OpenCode or OpenRouter and the whole stack costs nothing.
What the DeepSeek Harness desktop app is
DeepSeek Harness is an open-source agent harness — MIT licensed, 243K+ GitHub stars, built on an “everything is a plugin” architecture. Until v0.2 you ran it from the terminal and opened the web UI in a browser. The desktop app wraps the same harness in a native window, so you double-click and you’re in.
Think of it as an AI employee on your own computer: it codes, organises files, builds presentations and runs recurring jobs while you do something else. It sits in the same category as Hermes and OpenClaw, but its standout trait is how much you can customise through plugins.
- Native desktop app for macOS and Windows — no more running it in a terminal and opening a browser tab.
- Your history comes with you: my earlier sessions, projects and Obsidian vault were all there when I opened the app.
- Built-in plugin manager: web search, sub-agents, agent loops, shell, voice input and automation, switched on and off in one place.
- Bundled
dshcommand for installing plugins, managed from the menu bar — no separate Node or pnpm install. - Automation tasks: scheduled, recurring jobs that keep running in the background even when the window is closed.
- Better file handling: documents, spreadsheets, PDFs, charts and slide decks, with previews in the sidebar.
DeepSeek Harness desktop setup in five minutes
Here’s exactly how I set it up:
- Download the app from deepseek.com/harness — macOS (Apple Silicon) or Windows (64-bit). Full details in my download guide.
- Open it — any sessions from the web version appear automatically.
- Add a model provider in the models section. For free, pick OpenCode or OpenRouter and paste an API key.
- Start a new session, choose a project folder and a mode (I use Creator mode).
- Switch on the plugins you want — agent teams, voice input, automation — and get building.
The one step most people miss: choosing the mode. Standard works, but Creator mode is where you can build and customise plugins, which is the whole point of this harness.
| Mode | What it’s for |
|---|---|
| Standard | Everyday coding and file work — the default |
| PTC | Programmatic tool calling for more structured tool use |
| Minimal | A stripped-back loop with fewer moving parts |
| Creator | Building and customising your own plugins — the one I use |

Scheduled tasks, plugins and what’s coming
The automation task plugin is the feature I’m most excited about: set a recurring job — say, every Monday build a slide deck on the week’s AI automation news — and it runs on schedule, even with the window closed. Scheduled tasks are switched off by default, so turn them on in the plugin manager. The plugin ecosystem on GitHub is huge; my plugin guide covers the best ones.
On the roadmap, per DeepSeek:
- Stronger sandbox and security
- Better agent teams
- Personalised long-term memory
- GUI and browser automation
- Mobile access
- A plugin marketplace
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 DeepSeek Harness desktop
DeepSeek Harness desktop makes a powerful, customisable agent harness genuinely easy to use: one-click install on Mac or Windows, your history carried over, a plugin manager, scheduled automation, and free models if you want them. Keep private data out of it, pick Creator mode, and you have a free AI employee running on your own machine.
