One auto-update, one plugin conflict, one “quick CSS fix” — and suddenly a client’s homepage looks like abstract art. The worst part? You usually find out when they email you.
WordPress Auto-Updates Silently break layouts without warning
Plugin Conflicts You discover at 2am or Monday morning

What Our Clients Say
As an agency owner, WebChange Detector helps me keep the websites I maintain in check.
When you’re managing a larger number of sites, having a simple way to run quality assurance after updates, and to catch unexpected content changes, gets more and more important.
What really stands out is that the tool can detect layout shifts caused by dynamic content and account for them, so I’m only notified when there are real, meaningful changes.

Oliver, Bockpress
We had been looking for a solution like this for a long time and finally found it.
The tool has significantly streamlined our internal workflows and brought a new level of precision to our quality assurance. While focus naturally fades during manual checks, the tool reliably identifies even the smallest visual discrepancies.
This allows us to deploy our team much more effectively elsewhere.
The fact that the software is continuously being developed and the support impresses with quick response times perfectly rounds off the package.
Highly recommended for any agency!

Highly recommended for WordPress agencies! And just as valuable for freelancers managing WordPress sites on their own.

Serafin, eLearningWP
When managing nearly 50 websites, choosing the right tool makes a huge difference.WebChange Detector is the best visual monitoring tool I’ve ever used.
Its design is incredibly thoughtful – screenshots are taken after the page has fully loaded, so there are no blank or incomplete captures.
Since using it, I’ve saved a tremendous amount of time and significantly reduced visual fatigue from manual checking.
My only regret is this: I wish I had discovered it sooner.

Simple Setup For WP Websites
Connect Your WP Sites
Install our WordPress plugin on your client sites, or use the API. It takes about 30 seconds per site. We automatically detect all pages and posts.
Configure What to Watch
Choose which pages to monitor, how often, and on which devices (desktop, mobile, or both). Set your sensitivity threshold.
Get Alerted, Not Annoyed
When we detect a change above your threshold, you get an email with a side-by-side comparison. If nothing breaks, you hear nothing.
API & Webhooks
Integrate visual testing into your CI/CD pipeline. Trigger checks via API, receive results via webhook. Automate everything.
Desktop & Mobile
Choose to monitor desktop (1920px), mobile (375px), or both viewports.
Because let’s be honest: that hamburger menu bug only ever shows up on mobile, right when your client is demoing to their boss.
