Infinitus

Infinitus is one product on three screens: the macOS menu bar app that runs your Claude Code accounts (usage windows, swapping, the sessions on the Mac), the desktop and web app that drive the agents, and the phone app. This repository's main holds the desktop, web and phone apps and their server; the menu bar app lives in apps/mac, and one v<version> tag releases all of them together (#823). Site: infinitus.run.

What the desktop, web and phone apps add to the agent client:

• Accounts page — every engine's fleet with per-account usage bars, the switch / hold / star / rename actions, the forecast of the next reset, and lapsed AWS and gcloud sign-ins with their device codes.
• Settings › Infinitus — the menu bar app's preferences, notification routes, paired devices (the phone QR code and the tunnel), engines and lock, edited from the browser.
• Sidebar — an Accounts pill with the active account and its fullest window.
• Command palette — "Open accounts".
• Event toasts — the engine's events (a swap, a reset, every account exhausted) surface as toasts in the app shell.
• Phone — Accounts per paired Mac, and the Mac's account alerts as banners.
• Desktop — the run.infinitus.desktop app, state under ~/.infinitus, the menu bar app nested as a login item, and in-app updates from the GitHub releases.

Install: Infinitus-<version>-arm64.dmg from the latest release is the desktop app with the menu bar app nested inside as a login item — one download. The menu bar app alone: brew install --cask deathemperor/tap/infinitus (or Infinitus-<version>.zip from the same release); Linux gets infinitus-tray-linux-x86_64 / -aarch64 and infinitus-omarchy.tar.gz beside them. The engine is swapd.

How the apps talk to the menu bar app: only through its control socket (INFINITUS_CONTROL_SOCKET overrides the per-platform default), one JSON line each way; the engine's own files are never read.

For contributors: this tree builds on T3 Code, the upstream project. Upstream's main is merged in daily by the Upstream sync workflow as a pull request; the rules, registration points and the list of Infinitus-only files are in INFINITUS.md. Everything below the rule is upstream's README, untouched.

---

T3 Code is an "agent harness control surface". It enables control of the agents on your machine with a best-in-class mobile app (iOS, Android), web app and Electron-based desktop app.

Works with your subscriptions on Claude Code, Codex, Cursor, Grok Build, OpenCode, and Google Antigravity. If they're set up on your computer, T3 Code can control them.

"Wait, what are you selling me?"

Nothing. We built T3 Code because we wanted the best possible development experience with agents. We were inspired by existing solutions like the Codex desktop app, Conductor, Claude Desktop and Cursor Glass, but none met our bar.

We wanted something performant, remote-ready, and truly open. If we ever go the wrong direction, we want you to have everything you need to fork and build the editor that you want.

Installation

Warning

T3 Code currently supports Codex, Claude, Cursor, Grok Build, OpenCode, and Antigravity. Install and authenticate at least one provider before use:

• 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.

Try it out (install-free)

The easiest way to test T3 Code is to run the server in your terminal (requires Node.js 22.16+, 23.11+, or 24.10+):

npx t3@latest

This will launch T3 Code's backend on your machine as well as the local web app to control your agents.

Tip: Use npx t3@latest --help for the full CLI reference.

Desktop app

Install the latest version of the desktop app from GitHub Releases, or from your favorite package registry:

Windows (winget)

winget install T3Tools.T3Code

macOS (Homebrew)

brew install --cask t3-code

Arch Linux (AUR)

Stable:

yay -S t3code-bin

Nightly:

yay -S t3code-nightly-bin

The AUR packaging is maintained in this repository under packaging/aur.
