Detect plugin and theme conflicts before they break your site, with health scores, bloat checks, and safe one-click rollbacks.

Guardian – Conflict Detector & Safe Updates

Guardian is a safety net for your WordPress site. It scans your active plugins and theme for the conflicts that quietly break sites, scores how well-maintained your plugins are, helps you pinpoint the culprit when something goes wrong, and lets you roll back a bad update with one click.
Most conflict tools only help after a site breaks. Guardian is built around three ideas: prevent, detect, recover.
What it detects
<ul>
<li>Duplicate shortcodes registered by more than one plugin</li>
<li>Duplicate custom post types and taxonomies</li>
<li>Duplicate REST API routes</li>
<li>Duplicate AJAX actions</li>
<li>Duplicate script and stylesheet handles</li>
<li>Order-sensitive hook collisions (e.g. two plugins fighting over <code>the_content</code>, <code>template_redirect</code>, or WooCommerce checkout)</li>
<li>Cron events scheduled multiple times</li>
<li>Known incompatibilities — two caching plugins, two security/firewall plugins, two SEO plugins, and more</li>
<li>Duplicate WooCommerce payment gateways</li>
</ul>
Every issue gets a severity score (1–10), a plain-English explanation of what can go wrong, and a recommended fix.
Plugin Health Score
Guardian rates each active plugin out of 100 using public data from WordPress.org — last update date, active installs, ratings, support resolution rate, and compatibility with your WordPress and PHP versions — so you can spot abandoned or risky plugins.
Performance / Bloat scanner
See how much autoloaded data is loaded on every request, which plugins weigh the most, how many scheduled tasks are running, and your largest autoloaded options.
Binary-search troubleshooter
Disable plugins for your session only to find a conflict fast. Visitors keep seeing the live site the whole time. Disable half, reload, narrow down — the classic bisection method, built in.
One-click rollback
When enabled, Guardian copies a plugin&#8217;s files and settings just before WordPress updates it. If an update breaks something, restore the previous version in one click.
Lightweight by design
Scans run as scheduled background jobs and are cached. Nothing heavy ever runs on a normal front-end page load.

<h3>External services</h3>
This plugin connects to the WordPress.org Plugin API (https://api.wordpress.org/) when you use the Plugin Health feature. It sends the slug of each active plugin in order to retrieve that plugin&#8217;s public maintenance data (last update, install count, ratings, tested-up-to, required PHP). No personal data or site data is sent. See the WordPress.org privacy policy: https://wordpress.org/about/privacy/.
