Website Screenshot History: See How a Page Looked Over Time

Some changes are easier to see than to read. Screenshot history captures the page at each check so you can scroll back and see exactly how it looked — and when it changed.

How it works

  1. Add a URL

    Turn on screenshots for any monitored page.

  2. Screenshots are captured

    Site Monitor renders the page in a headless browser and saves a screenshot alongside the check.

  3. Review the timeline

    Browse screenshots in the site's history to compare before and after any change.

You choose which alerts each URL sends — downtime, content changes, slow responses — and we email you when they happen.

Useful for

  • Spotting broken layouts after a deploy
  • Keeping evidence of what a vendor or competitor page said
  • Showing clients how their site looked before an edit
  • Visual changes that don't alter text (images, colours, layout)

A visual audit trail

Text diffs show what the words were. Screenshots show what visitors actually saw. Together they give you a complete record — useful for compliance, disputes, and post-incident reviews.

Screenshot history is available on paid plans.

Frequently asked questions

Which plans include screenshot history?

Screenshot history is a paid-plan feature. The Free plan includes change detection and AI summaries so you can try the core product first.

Does it work on pages that load content with JavaScript?

Yes. Site Monitor can render the page in a headless browser before fingerprinting it, so content injected by JavaScript is included in the comparison.

Can it watch pages behind a login?

No. Site Monitor fetches public URLs the same way a browser would. Pages that require a login, CAPTCHA, or paywall can't be read.

Is Site Monitor free?

Yes. The Free plan covers 10 URLs checked every hour, with 2 AI change summaries a month — no credit card required. Upgrade only if you need faster checks, more URLs, or more AI summaries.
