ChangeTracker scans pages at the interval you choose, compares each version to the last, and sends a clear alert showing exactly what changed on the page.

Change detection works by taking periodic snapshots of a web page and comparing each new snapshot against the previous version. When differences are found, the tool identifies what specifically changed — text content, pricing, images, or page structure. ChangeTracker uses both text-based and visual change detection. Text detection is ideal for catching data-driven changes like price updates, while visual detection captures layout changes, image swaps, and design updates. The combination means you won't miss any meaningful page update. Unlike developer-focused tools that require CSS selectors or XPath configuration, our website change detector works with just a URL. Paste it in and detection starts immediately. We handle the heavy lifting of monitoring, comparison, and alerting so you can focus on acting on the changes that matter.
