Iframe Detector is a Chrome extension designed for developers and QA professionals to detect, highlight, copy, and export every iframe on a webpage, including same-origin, cross-origin, ads, and trackers.

It counts every iframe, whether visible or hidden, as soon as the tab loads. The extension color-codes iframes by origin and type, drawing a dashed outline around each frame with a corresponding badge. Users can easily copy the URL or open the full <iframe> tag with a single click. Exports can be done in JSON, CSV, or Markdown formats to suit various tools. The extension prioritizes privacy by only collecting anonymous, aggregate usage events without sending URLs, page content, or personal identifiable information. Installation is straightforward with one click from the Chrome Web Store, requiring no account or setup. Users can scan any page by clicking the toolbar icon to list all detected iframes.
