Website change monitor

Zetlyn watches a public web page and tells you when it changes: one place on it, or the whole page. You get what was there before and what is there now, not forty lines of changed HTML.

What people watch

One place, or the whole page

Click a place on the page and Zetlyn watches just that. When the page is rebuilt it finds the place again by what stands beside it, and if it cannot be sure, it asks you to mark it again instead of reporting a change that is not one.

Watch the whole page and Zetlyn compares it line by line. Clocks, counters and adverts that change on every visit are noticed when you start and never reported. The change message lists the lines that went and the lines that came.

How often

Every hour. With a subscription, every 15, 5 or 1 minutes, chosen per watch.

Pages that are made by scripts

Some pages only show their content once their scripts have run. Zetlyn reads those in a browser on its own servers, in Germany. Pages behind a login, a paywall or a captcha are not read.
