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
- ✓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.
Works on any site — from WordPress to AI-built sites.
- 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 check (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.
