Website change detection, down to a single element

Monitor any page, decide how often to check, and get told exactly what moved. No scrapers to build and nothing to maintain.

Watch

See exactly what changed

The change is highlighted inline, so you read the difference instead of hunting for it across the page.

How it works

Built to read a page the way you would.

Fetch the page, compare it against the last snapshot, and say exactly what moved, on whatever interval the page deserves.

The page is fetched on a schedule

From every 5 minutes to once a day. We request the same public page a browser would, at a polite rate, identifying ourselves in the user agent.

Compared against the last snapshot

Policy and rule text is compared in full, because one reworded clause is the signal. Anywhere else you narrow to a single element, so banners and counters never count as news.

You get the change, not the page

The alert carries the old wording beside the new one, and the snapshot behind it is dated. Nobody opens the page to find out what happened, or scrolls it to find where.

The alert shows up where you already work, email, Slack, Teams, a webhook, or a sheet

Any public web page: competitor pricing and plan pages, product and changelog pages, terms and policy pages, regulator and standards pages, investor-relations filings, or your own site. If you can open it in a browser, ChangeDetection can watch it.

When a page changes, you should not be the last to know.

Tell us which pages you have to watch. We check them on your schedule and alert you the moment the wording moves.
