v0.2.0

Unofficial desktop build of the DeepSeek Harness, not affiliated with DeepSeek.

This release is about updates. The app now notices when a newer desktop build is published, and the repository follows the Harness's own releases on npm.

What's new

The app tells you when it is out of date. Shortly after launch it checks this repository's latest release and, only if there is a newer one, offers to open the download page. A prompt can be dismissed for that version, and Help → Check for Updates… asks on demand. The check reads the redirect from /releases/latest rather than calling the GitHub API, so it spends none of the API's 60 anonymous requests an hour — a budget that is often already gone behind a shared or carrier-grade address. A check that fails is logged and forgotten: it never delays startup or interrupts.

Nothing is downloaded or installed for you. Without a developer certificate, an app that replaced its own binary would be executing an unverified download, so it reports and leaves the decision to you.

The bundled Harness is followed automatically. A scheduled workflow compares the pinned version against npm's latest daily and, when they differ, opens a pull request touching only that pin and starts a full build of the branch: all four platforms packaged, then the Linux and Windows builds installed and launched. Merging and releasing stay deliberate, because a developer-preview upstream can change the two things this shell depends on — the dsh web --port interface and the line it prints when the server is listening.

Still bundling Node 24.19.0 and @deepseek-ai/dsh@0.1.0-rc.6, unchanged from 0.1.0. Your sessions and configuration live in ~/.dsh and are untouched by installing over an earlier version; quit the app first.

Downloads

Platform	File
macOS (Apple Silicon)	…-arm64.dmg
macOS (Intel)	…-x64.dmg
Windows x64	…-x64-setup.exe
Linux x64	…-x86_64.AppImage or …-amd64.deb

Before the first launch

These builds carry no developer certificate, so both desktop OSes will stop them.

macOS — the app is ad-hoc signed but not notarized. Copy it to Applications, then clear the download quarantine before you first try to open it, because macOS caches its verdict:

xattr -dr com.apple.quarantine "/Applications/DeepSeek Harness Desktop.app"

Windows — SmartScreen shows Windows protected your PC. Choose More info → Run anyway.

Known limitations

• No developer certificate or notarization, hence the warnings above.
• Updates are announced, not installed.
• The Linux and Windows installers were installed and launched by CI before this release was published. The Apple Silicon build was installed and launched by hand; the Intel build was not, having no machine to try it on.

v0.1.0 — DeepSeek Harness Desktop

First desktop build of the DeepSeek Harness. Unofficial and not affiliated with DeepSeek.

The installer carries its own Node 24.19.0 runtime and a pre-installed @deepseek-ai/dsh@0.1.0-rc.6, so nothing needs to be installed first. The app runs dsh web as a child process and loads its UI, which means every Harness feature behaves exactly as it does from the CLI. Your sessions and configuration live in ~/.dsh, shared with the CLI if you already use it.

No API credentials are bundled. On first run the Harness asks for a provider key, exactly as the CLI does.

Known limitations

• No developer certificate or notarization, hence the warnings above.
• No auto-update. Help → Desktop Releases opens this page.
• The upstream Harness is still a developer preview, so expect breaking changes.
• One backend per machine: launching again focuses the existing window.

How these builds were checked

The Linux and Windows installers are installed and launched on a clean runner in
the same workflow that produced them, and the release is blocked unless the
bundled Node starts the bundled Harness and the reported URL serves the web UI.
Both macOS builds were verified by hand: valid signature, correct architecture,
and a real launch of the app from the mounted disk image.
