DeepSeek Harness Desktop

A self-contained Windows desktop shell for the DeepSeek Harness Web UI. Double-click the exe and the app opens in its own native window — no npx command and no browser are needed. The bundled Node server, every plugin, and the built web frontend all ship inside the package; the target machine needs no Node.js installation.

Built entirely with DeepSeek Harness (dsh). This repository — the Electron shell, the payload build pipeline, the CI workflow, and this README — was produced end to end by an agent running inside DeepSeek Harness (dsh).

See the build process record for screenshots and cost.

Downloads

Every release publishes two artifacts:

The first launch extracts the server payload once (~30 s); later launches start in a few seconds. App data (sessions, settings, profiles) lives in ~/.dsh, exactly as the CLI writes it.

What this project is

DeepSeek Harness ships a browser UI (dsh web, served on http://127.0.0.1:3080). This project wraps it as a desktop app:

• main.cjs — the Electron main process. It spawns a bundled node.exe against the bundled server payload, waits for the dsh web: URL line, then opens a BrowserWindow on that origin. The harness never runs inside Electron's own Node runtime (its native addons are ABI-matched to the bundled Node).
• scripts/build-server.mjs — produces server/, a production pnpm deploy closure of @deepseek-ai/dsh with every @deepseek-ai/* workspace package (including peer-only and vendored ones, and koffi's native FFI binding) re-materialized as real, symlink-free files.
• scripts/archive-server.mjs — packs server/ into a single server.tar.
• scripts/copy-node.mjs — copies the active Node executable to node/node.exe.
• scripts/sync-version.mjs — copies the harness version into package.json.
• after-pack.cjs — electron-builder hook that places server.tar and node.exe into the packaged resources/.

Why the tar archive

The server payload has ~34 000 files under node_modules. electron-builder's extraResources filter drops a node_modules directory directly under a from directory, and NSIS's File /r silently drops files past a large file count. Shipping one server.tar (extracted once into userData on first launch) keeps the portable installer to a handful of files and sidesteps both limits.

Build process

Prerequisites

• Node.js ^22.19 || >=24
• pnpm 11.x
• A DeepSeek Harness checkout (cloned and built)

1. Build the harness

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

2. Build the desktop package

cd deepseek-harness-desktop
npm install                        # electron + electron-builder
node scripts/build-server.mjs --harness ../deepseek-harness
node scripts/copy-node.mjs
node scripts/archive-server.mjs
node scripts/sync-version.mjs ../deepseek-harness
npx electron-builder --win portable zip --publish never

Or, once the harness is built, run npm run dist (it chains the server payload, node copy, archive, and packaging steps).

Outputs land in dist/:

• dist/DeepSeekHarness-<version>-portable.exe
• dist/DeepSeekHarness-<version>-x64.zip (electron-builder's zip target)

On a network that cannot reach GitHub directly, set these before npm install and electron-builder:

export ELECTRON_MIRROR=https://npmmirror.com/mirrors/electron/
export ELECTRON_BUILDER_BINARIES_MIRROR=https://npmmirror.com/mirrors/electron-builder-binaries/

Continuous integration

.github/workflows/build-release.yml keeps releases in sync with upstream:

• Monitor — a scheduled job polls deepseek-ai/deepseek-harness (its master branch package.json version) every 6 hours.
• Version sync — the desktop release uses the exact upstream version (e.g. 0.1.0-rc.6); a build runs only when the version has moved (or on workflow_dispatch, optionally with force).
• Build — on windows-latest: checkout the harness, pnpm install + pnpm run build, build the server payload, then electron-builder the portable exe and the zip.
• Release — publishes a GitHub release tagged v<version> with both artifacts (marked prerelease when the version contains -).

中文说明

DeepSeek Harness 桌面版：把 DeepSeek Harness 的 Web UI 封装成独立的 Windows 桌面程序，双击即可在原生窗口中使用，无需 npx 命令、无需浏览器。 程序内置了 Node 运行时、全部插件和已构建的前端，目标机器无需安装 Node.js。

本仓库（Electron 外壳、载荷构建脚本、CI 工作流、本 README）全程由 DeepSeek Harness（dsh）中的 agent 完成。

构建过程截图与花费见 构建过程记录。

每次 Release 提供两种产物：-portable.exe（双击即用）与 -win64.zip （解压即用）。构建流程见上文；CI 会每 6 小时监控上游版本，版本更新时自动编译 exe 与 zip 并发布同名版本号的 Release。项目采用 MIT 协议开源。
