FAQ

Visual Monitoring Questions

Everything you need to know about our screenshot monitoring.

What is visual regression testing?

Visual regression testing is an automated technique that captures screenshots of your web pages and compares them over time to detect changes.

How does PageRadar detect visual changes?

PageRadar captures full-page screenshots at your chosen frequency (hourly, daily, or weekly) and compares them pixel-by-pixel with previous versions. When changes are detected above your threshold, you receive notifications with side-by-side comparisons showing what changed.

Can I monitor both desktop and mobile layouts?

Yes! PageRadar captures screenshots for both desktop (1920x1080) and mobile (375x667) viewports.

How often are screenshots captured?

You can choose the monitoring frequency that you need : hourly for important pages that change frequently, daily for regular monitoring, or weekly for stable pages.

How do I avoid false positives from intentional changes?

PageRadar allows you to set thresholds. You can configure what percentage of change triggers an alert, helping you focus on changes that matter, ignoring minor variations.
