What changed on this page?
Paste any web address. We'll compare the page with the copy the Internet Archive saved a while ago and tell you what's different, in plain English.
How it works
Paste the address of any public web page. We load the page as it is today, then find the copy the Internet Archive (the Wayback Machine) saved about a week, a month or a year ago. We compare the two versions line by line, skip the things that change on every visit, like dates, counters and rotating banners, and write up what's left in plain English: prices that moved, products added or removed, wording that changed. If nothing changed in the last month, we look a year back so you still get a useful answer.
Choose every change over the past year for a timeline instead: we compare the archive's copy from each month with the next one, and the last with today, so you see when each change happened, not just the difference between then and now. It uses 3 of your free checks for the day.
What people check with it
- A competitor's pricing page, to see whether they've raised prices or changed their plans since you last looked. For ongoing alerts, see competitor price monitoring.
- Terms, policies and fees, to spot a new charge or a changed refund rule before it catches you out. More on terms and policy change alerts.
- Careers pages, to see which roles appeared or disappeared recently.
- Government guidance, to check whether rates, deadlines or rules have been updated.
From one check to every change
This tool answers "what changed?" once. A website change monitor answers it every time: ChangeGist checks the page on a schedule and emails you a short summary only when something you care about changes, with any deadlines added to your calendar. For a single product's price, the free price tracker emails you when it moves. Our guide on how to see what changed on a web page covers other ways to do it, including by hand.
Questions
How can it tell what changed if you've never seen the page?
We compare the page as it is now with the copy the Internet Archive (the Wayback Machine) saved about a week, a month or a year ago, and explain the differences in plain English.
Is it really free?
Yes, with no sign-up. To stop it being misused there's a small daily limit per person.
Can I see every change over a whole year?
Yes. Choose “every change over the past year” and we compare the Internet Archive's copy from each month with the next, then the last one with the page today. You get a dated list of what changed and when. It counts as 3 of your free checks for the day.
Why does it say there's no earlier copy?
The Internet Archive doesn't save every page. Smaller or newer pages often have no copy. ChangeGist can start watching the page from today, so you'll know about every change from now on.
Can it email me next time the page changes?
That's what ChangeGist does: it checks the page on a schedule and emails you a plain-English summary whenever something important changes. Free for 7 days, no card needed.
