Frequently Asked Questions

Common questions about WebChange Detector: Visual Regression Testing & Visual Checks After Updates

These are the three check modes the plugin offers. Auto-update checks are fired automatically by the WordPress auto-update system: a "before" screenshot right before the update runs, an "after" screenshot right after, and an email if anything looks different. On-demand checks are run by you on demand, typically right before and after a deploy or update you trigger yourself. Monitoring is a recurring schedule that catches changes nobody pushed. You can use one, two, or all three at the same time.

Yes. WebChange Detector is the visual-verification layer those tools might not provide. Run your updates through whichever dashboard you already use, and let WebChange Detector handle the before/after visual diff. On-demand checks can be triggered from the WordPress admin, the webapp or the REST API, so you can also wire them into your own scripts or pipelines.

Yes. WebChange Detector supports HTTP basic auth credentials and an optional static IP proxy that you can whitelist in your firewall.

Manual QA does not scale, you forget pages, and you cannot remember the exact pixel state from yesterday. WebChange Detector compares the rendered page at the pixel level on desktop and mobile, highlights the differences, and emails you only when something actually changed.

The AI is trained to recognize dynamic elements that are designed to change every page load: image sliders, ad slots, randomized testimonials, live counters. You can also create your own per-URL or per-website rules to ignore specific classifications permanently.

Yes. The plugin supports both network-activated and per-site activation modes. From the network admin you can register sub-sites, set per-site allowances, and run pre/post screenshots across the whole network during auto-updates.

Yes. URLs are synced per language and each language version is checked independently.

Yes. You can select per URL whether to check the desktop and/or mobile viewport.

Yes. We screenshot the rendered front-end, so any builder, theme, or block library is supported by default.

Yes. Every check has a public share link that opens the comparison view in a browser, no login required.
