详情介绍:
- Create a free WebChange Detector account at webchangedetector.com if you do not have one yet, then copy your API token from your account and enter it in MainWP.
- Enable the child sites you want to check.
- Sync each enabled child site's pages with "Sync WP URLs" so its pages become available, then select the pages to check (desktop and/or mobile).
- Click "Run visual checks & updates" on your MainWP dashboard or Updates page.
- The plugin captures pre-update screenshots, installs all pending updates, captures post-update screenshots and compares them. Before the pre-update screenshots and after the updates, the cache on each child site is cleared automatically, so the screenshots always show the real, freshly generated state of the site.
- Review the results on the Checks tab: every page with a visual change is flagged, including an AI summary of what changed.
- One-click safe updates: pre-update screenshots, updates, post-update screenshots, comparison: all in one run across all child sites.
- Automatic cache clearing: the child site's cache is cleared before the pre-update screenshots and after the updates, so screenshots never show a stale cached page. Works with 20+ caching plugins (WP Rocket, LiteSpeed Cache, W3 Total Cache, WP Super Cache and more) through the MainWP Child plugin, with nothing extra to install.
- Bulk or single site: run the flow for every enabled child site at once or for one site from its overview.
- Page selection per site: choose which URLs are checked, separately for desktop and mobile.
- Checks overview: all runs across your sites with filters, change percentages and side-by-side comparisons.
- Safe Update widget: start a run from a draggable, hideable widget on your Operations dashboard or a single child site's overview.
- Live run popup: a Pre-update, Updates, Post-update and Done timeline with per-site progress, and automatic resume if you navigate away mid-run.
- Account overview: your plan, remaining checks and renewal date on the Account tab.
- Auto-enable new sites: optionally provision every newly added MainWP child site for visual checks automatically.
api.webchangedetector.com only after you have entered your API token, and only in these circumstances: when you connect or verify your account, when you enable a child site or sync its page URLs (the public URLs and page titles of that site are transmitted), when you start a visual check (screenshots are taken of the selected public URLs), and when you review or update results. Your API token is sent with each request to authenticate your account. No data about your WordPress users or any non-selected content is transmitted.

常见问题:
What is an on-demand check?
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.
Do I need to install anything on my child sites?
No. The plugin runs entirely on your MainWP Dashboard and talks to the WebChange Detector service. Child sites are captured through their public URLs.
Do I need a WebChange Detector account?
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.
Which pages are checked?
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.
Why do I need to sync the child site's pages?
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.
What happens if a site is offline during an update 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.
Do I need to clear the cache on my child sites after updates?
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.
Does this work with MainWP updates started elsewhere (e.g. scheduled)?
Updates you start outside the plugin's own flow still trigger post-update screenshots as a safety net, so you can compare against the last baseline. For the full pre/post comparison, start the run from the "Run visual checks & updates" button.
