Chrome extension

Click the WebStatBot icon on any site and it runs the same checks as the free tools page — DNS, security headers, hosting, mail, WHOIS, blacklists — straight against the public API, no sign-up. It isn't on the Chrome Web Store yet, so for now it installs the way Chrome lets anyone install an unpacked extension.

⬇ Download webstatbot-tools-extension.zip

Install it (takes about a minute)

  1. Download the zip above, then extract/unzip it somewhere you'll keep it (e.g. a webstatbot-extension folder in Documents — Chrome reads the files from here every time, don't delete the folder afterwards).
  2. Open chrome://extensions in Chrome (paste that into the address bar).
  3. Turn on Developer mode — a toggle in the top-right corner of that page.
  4. Click Load unpacked and select the folder you extracted (the one that directly contains manifest.json).
  5. Click the puzzle-piece icon in Chrome's toolbar and pin WebStatBot so it's always visible.

Works the same way in Edge, Brave and other Chromium browsers — the page is just called edge://extensions etc. there instead.

What it does and doesn't do

Chrome will show an "Errors" badge or a warning about unpacked extensions — that's normal for anything installed this way rather than through the Web Store, not a sign something's wrong.
