About this plugin
Every plugin, theme, or WordPress core update is a gamble. Most of the time it’s fine. Sometimes it quietly breaks your checkout, blanks a page, or removes a feature — and you find out from a lost sale, not a warning.
Update Guardian watches for exactly that. You pick the pages that matter (home, shop, cart, checkout, a landing page). It captures a baseline while your site is healthy, then re-checks those pages and tells you what changed:
- Broken pages — HTTP errors, unreachable pages, and PHP fatal errors.
- Visual regressions — layout shifts and pages that collapse or grow unexpectedly, with a tolerance so normal variation doesn’t cry wolf.
- Silent feature loss — an element that was there at baseline (a product grid, a cart form, an “Add to cart” button) that has disappeared, even when the page still loads with a 200 status. This is the failure a plain “is the site up?” check misses entirely.
The markers it watches are derived automatically per page, so it works on any WordPress site — WooCommerce, a blog, a brochure site — with no configuration.
Plugin features and service plans
Every feature of this plugin is free and fully functional for everyone: manual
checks from the settings screen, and automatic checks after every plugin, theme,
or core update.
Plans only affect the external service that performs the page analysis:
- Free tier — no account or key required; the service analyzes up to 3
monitored pages per check.
- Paid plans — the service analyzes an unlimited number of monitored pages
per check.
How it works
The page analysis (loading each page in a real browser, capturing screenshots, comparing them, and detecting missing features) runs on the Update Guardian service, not on your server. Your site sends the service the addresses of the pages you chose to monitor; the service loads them, compares them to your baseline, and returns a report. This keeps the heavy work off your hosting.
External services
This plugin relies on the Update Guardian service to analyze your pages. It is required for the plugin’s checks to function.
What is sent and when: When you capture a baseline or run a check (manually, or automatically after an update), the plugin sends the service the public URLs of the pages you have chosen to monitor — plus your license identifier, if you have one (the free tier needs no account or key). The service then loads those URLs in a headless browser to capture screenshots and detect changes. No page content, credentials, or personal data from your site is transmitted beyond the page URLs themselves.
