A modern desktop experience for the DeepSeek Harness ecosystem (Plugin)

Download Desktop

Features

Desktop Bring the official DeepSeek Harness local Web UI to a native desktop application. The app starts and manages the local Harness service, integrates the system tray and desktop window, and requires no Node.js installation or command-line setup.	Mobile Remote Control Connect to Desktop from iOS and Android to start tasks, monitor Agent progress, and send follow-ups from your phone.
Plugin Marketplace Harness follows an “everything is a plugin” architecture. The desktop marketplace will make it easy to discover, install, update, and manage plugins for models, tools, interfaces, and workflows.	Channels Connect WeChat, Feishu, Discord, WhatsApp, and other IM channels to start tasks, receive progress updates, and continue conversations from the apps you already use.

Plugin Ecosystem

DeepSeek Harness is built on Cordis and follows an “everything is a plugin” architecture. Core capabilities such as model adapters, the tool registry, the session log, and the Agent Loop participate in the runtime as plugins, so they can be composed or replaced through configuration. External plugins can also join a runtime through profiles and bundles. See the official architecture overview and plugin management documentation.

We want Desktop to become more than a standalone desktop wrapper: it should serve as a desktop entry point into the DeepSeek Harness plugin ecosystem. We plan to reorganize the desktop capabilities around the official plugin model so service management, system integrations, and the plugin marketplace can follow the same composition model as Harness.

Coming soon: Desktop is not currently distributed as a DeepSeek Harness plugin. This plugin integration is still in development.

Relationship to the Official Project
