The Silent Chaos of WordPress Maintenance
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
Cascading Changes That ‘small change’ that broke the homepage
WebChange Detector watches your sites so you don’t have to
We take screenshots before and after changes, compare them with pixel-perfect precision, and alert you only when something actually breaks. No more manual checking. No more client surprises.

Serafin, eLearningWP
We’ve been using Web Change Detector for over a year across all our WordPress maintenance contracts, and it has become an essential part of how we work as an agency.
We explicitly include automatic visual change detection in our maintenance packages and communicate this as added value to our clients, allowing us to stay proactively on top of defined core pages.
Highly recommended for WordPress agencies! And just as valuable for freelancers managing WordPress sites on their own.

Jennifer, 7South Digital
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 — no extra charges either way.
Because let’s be honest: that hamburger menu bug only ever shows up on mobile, right when your client is demoing to their boss.
