Free, no sign-up. We pull your site's pre-Black-October snapshot from the Internet Archive, diff it against your live page, check whether crawlers see different content than humans, and give you a verdict in plain words. ~30 seconds.
We fetch your public homepage the way a visitor, a crawler, and the archive saw it. Nothing is stored except an anonymous scan count.
This scan is one moment in time. Set the free tripwire → and Hawkline watches these pages continuously: if they change and it wasn't you, you know in minutes, in plain words.
