ChangeRadar — Website Change Monitor

Track any web page for changes. Checks run on our servers every 30 minutes, so monitoring continues when your browser is closed.

Watch any web page and get told when it changes. Open the page you care about, click the toolbar icon, and save it. That's the whole setup. The checks run on our servers, not in your browser, so monitoring keeps going when Chrome is closed and when your laptop is shut. Pages are re-checked at most every 30 minutes. Whatever changed is waiting for you the next time you open Chrome, and the toolbar badge tells you how many watches have news. Useful for competitor pricing pages, supplier stock pages, policy and terms pages, grant and tender listings, job boards, and anything else that quietly updates without telling you. What it sends to our servers: the address and title of each page you asked us to watch, plus a random ID created on your device so we know which list is yours. There is no account, and nothing else about your browsing is collected.
