Visual regression monitoring — catch layout changes pixel-for-pixel.
Relvato screenshots your key pages — desktop and mobile — and compares them pixel-for-pixel against an approved baseline, so a surprise layout shift from a plugin or theme update never reaches your visitors unseen.
- ✓Key pages screenshotted on desktop and mobile
- ✓Any page of your own site, added by its address — a landing page, pricing, a form
- ✓Pixel diff vs. an approved baseline
- ✓Rendered in real Chrome, Firefox and Safari
- ✓Adjustable sensitivity — set how much change counts as a regression
- ✓Masks for dynamic regions (carousels, ads, timestamps)
- ✓The exact changed region is highlighted
A CSS regression doesn’t throw an error — the page still loads, it just looks broken: an overlapping header, a collapsed grid, an off-screen button. You’d only find it by looking at every page after every change. Relvato does exactly that, and shows you the diff.
Visual regression and structure drift catch different breakage. Our guide explains which one flags a moved hero vs a missing section — and why you want both.
- Screenshots your key pages in a real browser, desktop and mobile, on every change.
- Compares each shot pixel-for-pixel against a baseline you approved, ignoring masked regions like carousels or ads.
- Flags the exact changed area, so you can tell a real breakage from an intended redesign at a glance.
Won’t every intended change flag?
You approve a new baseline in one click when a change is intended, so only unapproved differences alert.
Do I need a plugin or a code snippet on my site?
No. Visual regression works entirely from the outside — Relvato screenshots your public pages in a real browser, so there's nothing to install and no script to add. The only step is a one-time domain-ownership verification (a meta tag or DNS record) on a non-WordPress site.
Can I tell it to ignore certain areas of a page?
Yes. You can mask dynamic regions — carousels, ads, live counters, timestamps — so they're excluded from the pixel comparison and never trigger a false alert. Everything outside the masks is still checked.
