Know when any webpage changes
Track edits, additions, and removals across any public webpage. From news articles to documentation pages, know the moment content is modified.
Websites change constantly — articles get updated silently, documentation gets rewritten, product descriptions evolve, and important pages disappear. DiffTrac watches any webpage and tells you exactly what changed, when it changed, and shows you the before and after. No more manually refreshing pages or wondering if something was different yesterday.
What you can do
Track any element on any page
Click on any text, heading, paragraph, image, or data element. DiffTrac monitors exactly what you selected and ignores everything else.
Before and after diffs
See exactly what changed with highlighted before/after comparisons. Red for removed content, green for added content — just like a code diff.
Works with JavaScript-heavy sites
DiffTrac runs a real browser to render pages. SPAs, React apps, dynamically loaded content — it all works. Even pages behind login walls.
AI-powered setup
Describe what you want to track in plain English. DiffTrac's AI picks the right elements, sets the schedule, and configures alerts automatically.
How it works
Enter any URL
Paste the URL of any webpage. DiffTrac loads it in a real browser, takes a screenshot, and shows you the page exactly as it appears.
Click what to watch
Click on the elements you care about — a paragraph, a data table, a status message. Name each one so you know what changed later.
Get change notifications
When content changes, you get a notification with the exact old and new values. Review the diff and decide if action is needed.
