COMMUNITY / DISCLOSURE
Identity first, experience second
This is not an official DeepSeek desktop app.
DeepSeek Harness Desktop is maintained independently by the open-source community. It does not represent DeepSeek or imply official endorsement. The Harness runtime comes from the official open-source project; this community repository owns the desktop packaging, releases, and support.
The missing native layer
Desktop convenience without changing how Harness stays open.
The Tauri 2 shell and Rust sidecar handle installation, windows, the tray, and the process tree. The agent harness continues to evolve in the official open-source project.
SUPERVISED
Close the window, the process stays supervised
A Rust sidecar starts, restarts and shuts down the whole Harness process tree. Crash detection and bounded restarts keep the runtime healthy.
PINNED UPSTREAM
Stable shell, official Harness inside
The official DeepSeek Harness is pinned and bundled with Node.js. Nothing is forked; upgrades are a version bump plus a full smoke test.
Two layers,
one supervised Harness.
The desktop shell changes only when the Tauri or sidecar layer needs to. The Harness runtime follows the upstream open-source project, and the sidecar keeps the process tree clean across restarts and shutdowns.

FAQ
Common questions
Short answers to the questions new users search for.
What is DeepSeek Harness Desktop?
It is a community desktop packaging of the official DeepSeek Harness. A Tauri 2 shell, a Rust supervisor sidecar, and a bundled Node.js runtime run the unmodified Harness web UI as a native Windows or macOS application.
Do I need to install Node.js or run commands in a terminal?
No. A pinned Node.js runtime is bundled inside the app, and the supervisor starts the Harness automatically. Your system Node installation, if any, is never used.
Is this an official DeepSeek product?
No. It is maintained by the web-casa community. The DeepSeek Harness package itself is official and unmodified; this project only pins it and packages it.
