Unofficial community desktop wrapper. DeepSeek AI maintains the official Harness; this fork maintains only the app shell and installers.

The experience

A fully native DSH experience.

The desktop edition starts its window and Harness Host together. No browser address, port configuration, or terminal that must stay open.

One clickThe app and Host launch together

Zero listening portsThe interface uses private IPC

Isolated stateNo Web UI directory or session collision

Official Harness at the core

Everything familiar.
Nothing missing.

Projects, sessions, plugins, tools, and the agent runtime still come from the official Harness. The desktop layer handles only application lifecycle, native installation, and private process communication.

Desktop additions

Extend, update, and control.
Inside the app.

Community extensions, verified desktop updates, and encrypted phone control each have a clear entry point without leaving the Harness workflow.

NEXA Remote

Remote Control

The first-class qrcode-remote runtime component adds one compact Connect mobile icon beside Settings. Click it and scan the generated code in WeChat to open the computer's mobile-adapted control interface immediately. Follow running work, approve requests, send or stop a task, create a Session, select or create a computer workspace, and change low-risk settings; every action still executes on the paired computer.
