Track the active window on Windows, macOS, and Linux with a sync-friendly API on Windows.

npm install win-track

const { getActiveWindow } = require("win-track");

const info = getActiveWindow();
console.log({
  appName: info?.appName,
  title: info?.title,
  url: info?.url,
  id: info?.id,
  bounds: info?.bounds,
  owner: info?.owner,
  memoryUsage: info?.memoryUsage,
  website: info?.website
});

For a one-off async fetch:

const { getActiveWindowAsync } = require("win-track");

async function run() {
  const info = await getActiveWindowAsync();
  console.log(info);
}

run();

• getActiveWindow() - Fetch the active window info.
• getActiveWindowAsync() - Fetch the active window once.
• getLastError() - Return the last error from getActiveWindow, if any.

• Windows uses a native addon built with C++/N-API.
• Linux (X11) uses xprop and xwininfo for active window metadata.
• macOS uses AppleScript (osascript) for the frontmost app/window.
• URL extraction uses Windows UI Automation and supports Chrome, Edge, Firefox, and Brave.
• macOS URL extraction uses AppleScript for Safari, Chrome, Edge, Brave, and Firefox; Firefox falls back to a clipboard-based method, so grant Accessibility permissions and expect the clipboard to be temporarily used.
