SumeetSarna – Update Guardian is a WordPress plugin designed to help site owners monitor the health of their key website pages following updates to plugins, themes, or the WordPress core. It addresses the risk that updates can sometimes introduce regressions, such as broken pages or missing features, which may go unnoticed until they impact users or result in lost sales.
The plugin allows users to select specific pages that are critical to their site, such as the homepage, shop, cart, checkout, or landing pages. It captures a baseline snapshot of these pages when the site is functioning correctly. After each update, Update Guardian re-examines the selected pages and identifies any changes from the baseline. The tool detects broken pages by checking for HTTP errors, unreachable pages, and PHP fatal errors. It also monitors for visual regressions, such as unexpected layout shifts or changes in page size, while allowing for a tolerance to account for normal variation. Additionally, the plugin flags silent feature loss, such as when an element present at baseline—like a product grid, cart form, or "Add to cart" button—disappears after an update.
Update Guardian is intended for WordPress site owners and administrators who want to proactively catch issues before their customers encounter them. The plugin operates within the WordPress environment, integrating directly into the site's workflow.
