It has no ads and no analytics. To show an extension, it downloads that package directly from Google's servers, the same way Chrome does when you install something. Files you open from your computer are read on your device and are never uploaded. ❓ FAQ Do I need to install the extension I want to inspect? No. The package is downloaded and shown as files. It is never installed or run. What is the difference between ZIP and CRX? CRX is the signed package format the Chrome Web Store uses. ZIP is the same files in a format any computer can open. Can I open a file I already downloaded? Yes. Open the viewer from the settings page, then choose the file or drop it onto the page. Why can't I open some extensions? The store does not provide packages for some items, for example unpublished, paid or region-restricted ones. The viewer tells you when this happens. Does it work with Firefox or Edge add-ons? Not yet. This version supports the Chrome Web Store and package files on your computer. 💬 If it saves you time, a short review on the Chrome Web Store helps other people find it. Free to use.
