Install and launch DeepSeek Harness in one click.

🥇 The most foolproof DeepSeek Harness launcher 🥇

DeepSeek Harness (dsh) has no desktop app of its own and installs through a terminal. Summono gives it one. Click the whale, and dsh is installed, running, and ready to chat — no terminal, no commands, no setup. Claude Desktop and the Codex (ChatGPT) app launch from the same screen.

The launchpad — one click on any icon:

Talk to us

Issues are welcome any time: open one, in English or Chinese. And come find me on X: @liustack — which harness should get one-click support next, what broke, what should come next. New releases land there first.

Highlights

• Installed and chatting in one click. The whale icon covers everything: a private Node.js runtime, dsh itself, startup, and the chat UI opening right inside the app. Zero terminal, zero commands.
• Official apps, direct. Claude Desktop and the Codex (ChatGPT) app launch if installed, and install in one click if not — App Store-style progress ring included.
• Fully compatible with a hand install. The hosted dsh reuses the official state directory, so every tutorial on the internet still applies, and a copy you installed yourself keeps working untouched.
• Free forever. MIT. No paid tier, no "pro" features, no ads.

Install

Download from Releases: .dmg for Mac, .exe for Windows.

Mac builds are Developer ID signed and notarized by Apple — download, drag to Applications, double-click, done.

On Windows, if a blue SmartScreen prompt appears, click "More info" → "Run anyway".

v0.1 is verified end to end on macOS; Windows real-machine verification is next in line.

Developers can run from source:

pnpm install
pnpm dev

Contributing

Summono does not accept pull requests. The project is maintained by a single author who reviews every line, which is a deliberate choice for reliability. Two effective ways to contribute:

• Open an issue. Bugs, suggestions, confusing errors, unclear docs. Issues are read and shape what gets built next.
• Fork it. Under MIT your copy is fully yours to modify and publish.

Details, including how the code is organized, in CONTRIBUTING.md.

Shameless plug

This project runs on LIUSTACK Skills: shaping before you build, coding while you build, dig when it breaks, snapshot when you hand off. Lighter than Superpowers, and stronger.

⭐ If it helps, star Summono and VibeMaster. Stars are how the next developer finds them.

Key ecosystem partners

The projects worth recommending in the DeepSeek Harness ecosystem.

• 👁️ ModLens — Plug-in vision for the text-only DeepSeek and GLM models: paste an image straight into the chat and it reads it. 为纯文本 DeepSeek / GLM 模型补上视觉能力的外挂插件,图片直接粘贴进对话就能读。
• 🔎 ModSearch — Plug-in web search, X search, and page fetch for models without native web access. 为没有联网能力的模型补上网页搜索、X 搜索和页面抓取。
