Frequently Asked Questions
Common questions about WebChange Detector for MainWP
An on-demand check is a visual diff you run around a change you make yourself. WebChange Detector takes a screenshot of each selected page before the change, you apply the change, it takes another screenshot after, and the two are compared automatically on desktop and mobile. In MainWP this is wrapped around the updates you run: the plugin captures the pre-update screenshots, installs the updates, captures the post-update screenshots, and shows you every page that changed, with an AI summary. The AI ignores moving parts like sliders, carousels and ads, so you only get flagged on real changes.
No. The plugin runs entirely on your MainWP Dashboard and talks to the WebChange Detector service. Child sites are captured through their public URLs.
Yes. The screenshots are captured and compared by the WebChange Detector service, so you need an account and API token. A free plan is available.
You choose. After enabling a child site, its published pages and posts are synced and you select which URLs are checked, separately for desktop and mobile. Every selected URL and device counts as one check per capture.
Before it can check a site, the plugin needs the list of public URLs on that site. Syncing fetches the published pages and posts from the child and makes them available for selection. It runs automatically when you enable a site and again after MainWP syncs the child. Until a site is synced, there are no pages to select and no checks can run.
The run tolerates it: the offline site is skipped for updates and the other sites continue. The post-update screenshots still run for the sites that were updated.
No, the plugin does that for you. It clears each child site's cache before the pre-update screenshots and again after the updates, using the cache clearing built into the MainWP Child plugin (supports 20+ caching plugins, detected automatically). This makes sure the comparison shows the actual state of the site after the updates instead of a cached old version. If no supported caching plugin is active, this step is simply skipped.
No. Only updates you start with one of the plugin's own "with Checks" buttons are checked. Updates started with MainWP's own update buttons, and scheduled or automatic updates, run without any screenshots or comparisons, so they never use check credits.
