Superagent Desktop

Superagent

A home for your agent.

A free, open-source Mac app for Claude Code, OpenAI Codex and Google Antigravity: a desktop GUI where your AI coding agent works next to a real browser it drives, an iOS Simulator in the window, and your iPhone in the loop. Run several agents in parallel, each on its own git branch. No API key: it runs on the subscription you already have.

Your agent already writes the code. Superagent gives it a place to work — and
gives you a place to watch. Every project is a chat sitting next to the thing
being built: a real browser on the sites you're already logged into, the files
it's editing, an iOS Simulator streamed straight into the window. Every chat
works in its own copy of the project, so nothing collides. And when you leave
the desk, the iPhone app follows the conversation and lets you answer the
agent's questions from anywhere.

Everything runs locally on your Mac, on the agent subscription you already have
— Claude Code, Codex or Antigravity, switchable per chat. No middleman server, no API key, no
AI of its own — and the whole app is open source, so you can read exactly how it
touches your browser.

For Antigravity, install the agy CLI and run agy in Terminal to sign in with
Google, then select Antigravity in the chat’s agent picker. Its model picker
reads the models available to your account.

What it does

Build it and watch it, side by side. The chat sits next to a real browser.
Ask for a change and watch the page update in the same window — no alt-tabbing
to find out whether it worked. Point it at a local dev server or any live site;
