DSH Codex Desktop is a community-maintained desktop distribution of DeepSeek Harness. It is not an official DeepSeek AI product.

DSH Codex Desktop turns DeepSeek Harness into a native, ready-to-run desktop workbench. The installer includes the required Node.js runtime and local DSH runtime: install it, open it, then start working. You do not need to prepare a Node.js environment or launch DSH from a terminal.

Download and start

Get the current installer from GitHub Releases.

1. Download the package for your platform.
2. Install and open DSH Codex Desktop.
3. Wait for the built-in local DSH service to finish starting.
4. Create a task, select a model and permission mode, then work in your project.

The application keeps DSH data in your existing user profile (%USERPROFILE%\.dsh on Windows), so sessions and settings remain available after application upgrades.

A complete desktop workbench

Product preview

Dark workspace: project context, a long-running task, and the desktop conversation surface.

Light workspace: the same task surface in the light theme.

Inspect context composition while the extensible workspace sidebar keeps project files within reach.

Archived conversations stay searchable and can be restored from Settings.

Manage the skills available to DSH and your Agents.

Connect channels for IM-assisted workflows.

Enable only the expert presets that match the current task.

Included on first launch

The installer ships with the local runtime required to start DSH. On first launch, it prepares the desktop-facing community plugins in the Web profile:

You can later manage additional plugins from the plugin market. The desktop application keeps its own runtime separate from profile-installed community plugins so plugin changes do not overwrite the application runtime.

DSH product ecosystem

DSH Codex Desktop combines the core runtime, feature products, and plugin market into a ready-to-install desktop product. The same products can also be used separately for other DSH setups:

Updates and recovery

• Desktop updates are checked after startup by default and notify you when a new release is available. Settings → Updates can instead download releases automatically or switch to manual-only checks. Installation and restart always require an explicit action.
• DSH reload is available from the tray menu after changing plugins or profile configuration; it restarts the local DSH service without reinstalling the desktop application.
• Plugin updates remain in the DSH settings and plugin market. A failed plugin installation is not activated as a running bundle.
• Startup recovery removes stale community-plugin registrations that no longer have an installed package, then retries the local DSH startup.

System requirements

Privacy and security

• DSH configuration, sessions, and credentials remain in the current user's DSH directory. Uninstalling the desktop app does not delete them.
• The launcher accepts only validated 127.0.0.1 local HTTP addresses for its embedded window.
• External HTTP(S) links open in the system browser. File, JavaScript, and data URLs are blocked.
• Electron uses context isolation and sandboxing, with Node.js integration disabled for the DSH page.
• Your configured model providers and DSH tools may make their own network requests. Review their settings and privacy policies before use.

Development

Development requires Windows, Node.js 24.19.0, and pnpm 11.22.0.

[Console]::OutputEncoding = [System.Text.Encoding]::UTF8
$OutputEncoding = [System.Text.Encoding]::UTF8
pnpm install --frozen-lockfile
pnpm test
pnpm run dist

Local build artifacts are written to release\ and are not committed. Pushing a vX.Y.Z tag starts the packaging workflow for Windows x64, macOS arm64/x64, and Linux x64 AppImage / deb artifacts.
