Macotron does everything.

Tile windows, bind hotkeys, drive the menu bar, read sensors, capture the screen, talk to models. From small JavaScript files that reload when you save them.

Download for macOS Source on GitHub

Free and open source. Built with Swift and QuickJS.

// ~/Macotron/plugins/tile.js
macotron.keyboard.on("Tile Left", "ctrl+opt+left", () => {
  const win = macotron.window.focused();
  macotron.window.moveToFraction(win.id, {
    x: 0, y: 0, w: 0.5, h: 1,
  });
});

Save the file. The hotkey is live.

Capabilities

Plugins

The catalog ships 73 built-in plugins. First launch copies the ones you pick into plugins/. Macotron writes an AGENTS.md next to them so a coding agent already knows the API. Open a file in the finder to read the script this site ships.

Host API

Everything hangs off macotron.*. Apple-shipped tools only. Plugins call these namespaces to tile windows, read sensors, and talk to models.
