Xen Code

Xen Code is a desktop control surface for the coding agents on your machine. It works with your own subscriptions to Claude Code, Codex, Cursor, Grok Build, OpenCode, Google Antigravity, and fx: if they're set up on your computer, Xen Code can drive them.

Xen Code is a fork of T3 Code by T3 Tools Inc., used under the MIT License. The architecture, the server, and the large majority of the code are their work. Xen Code is not affiliated with or endorsed by T3 Tools.

Installation

Install and authenticate at least one provider first:

• Codex: install Codex CLI and run codex login
• Claude: install Claude Code and run claude auth login
• Cursor: install Cursor CLI and run agent login
• Grok Build: install Grok Build CLI and run grok login
• OpenCode: install OpenCode and run opencode auth login
• Antigravity: enable it in Settings, then use Install Antigravity and Sign in with Google. No CLI is required.
• fx: install fx and run fx login (setup guide)

Then download the desktop app from GitHub Releases:

• Windows: Xen-Code-<version>-x64.exe
• Debian, Ubuntu: sudo apt install ./Xen-Code-*.deb
• Other Linux: Xen-Code-<version>-x86_64.AppImage

The app updates itself from the same releases page.

Documentation

Full docs live in docs/. Many pages still describe upstream T3 Code; features that depend on T3's hosted services (T3 Connect, the hosted web app, the mobile apps) are not part of Xen Code builds.

Building from source

Start at docs/internals/overview.md. The repo uses Vite+, so install the global vp tool (guide):

curl -fsSL https://vite.plus | bash   # macOS / Linux
irm https://vite.plus/ps1 | iex       # Windows

Then:

vp i
vp run dev

Bugs and ideas go in Issues.
