Visual regression for WordPress
See exactly what changed on your site.
WP Diff screenshots every page on your site, keeps the history as a timeline, and compares any two snapshots region by region. A one pixel layout shift stays quiet. A real change gets outlined.
The problem
Pixel diffs cry wolf.
Classic screenshot tools compare pixel by pixel. When your header grows by one pixel, everything below it moves, the whole page lights up red, and the change you actually care about is buried.
WP Diff segments each screenshot into regions and looks for every region near its old position in the other snapshot. Content that only moved still matches, so it stays quiet. Only regions whose pixels really changed are flagged.
Pixel diff
Everything flagged
A one pixel shift cascades down the page. Hundreds of false positives per snapshot make the report unreadable.
Region diff
One region flagged
The block that changed is outlined on both snapshots. The content that merely shifted below it is left alone.
How it works
From page list to outlined change in four steps.
Step 1
Discover
The plugin builds the page list straight from your WordPress content: every published page, post, and public post type.
Step 2
Capture
Playwright takes a full page Chromium screenshot of every page and stores the set as a timestamped snapshot.
Step 3
Compare
Each screenshot is segmented into regions. Every region is matched against the other snapshot near its old position.
Step 4
Report
Only regions whose pixels really changed are flagged. You review them side by side with the change outlined.
WordPress plugin
A snapshot timeline inside wp-admin.
Install the WP Diff plugin, point it at a scanner, and your site gets a timeline of full site snapshots. Pick any two as baseline and compare, run scans on demand, and review outlined changes without leaving WordPress.
- Wayback style timeline of every snapshot, oldest to newest
- Compare last week against today, or against a month ago
- Your API token stays server side. The browser never sees it
