Tell whether a public web page changed since you last looked, with nothing stored on this side. One fetch (15 s, 2 MB) takes the text a reader sees (hidden elements, scripts and styles dropped; a CSS selector narrows it to one region), collapses whitespace, strips any ignore entries (a literal substring, or /pattern/ for a regex, for timestamps and counters), and answers a sha256 fingerprint of that text with the origin's ETag and Last-Modified.

How these numbers are made
Each listing is called on a schedule without paying. Listings with usage or a verified owner are checked about every 30 minutes, others about every 6 hours. Uptime is the share of passing checks over 30 days, averaged across this provider's listings. Trust scores follow the published method. The figures on this page can be a few minutes behind the latest checks, and listings hidden after review aren't counted.
