Wp Core Tools

<p>Speedix profiles PHP execution on your WordPress site, showing exactly which hooks and plugins are slow. Unlike page speed tests that just show load time, Speedix shows you <em>why</em> your site is slow.</p>
<p>Built for developers, agencies, and site administrators who need to diagnose performance issues at the code level.</p>
<h4>What It Does</h4>
<p>Measures every WordPress hook with microsecond precision and traces slow callbacks back to their source plugins using PHP Reflection. You get a clear breakdown of where time is spent: Core vs Theme vs Plugins.</p>
<p>The dashboard shows a health score (0-100), highlights the slowest hooks, and tracks performance trends over time. WooCommerce sites get a dedicated tab with categories for Checkout, Cart, Products, Orders, and more.</p>
<h4>Safe for Production</h4>
<ul>
<li>Sample rate control (10-100% of requests)</li>
<li>Threshold filtering to only log slow hooks</li>
<li>Overload protection auto-pauses if overhead spikes</li>
<li>Auto-cleanup from 1 hour to 7 days retention</li>
</ul>
<p>Quick presets let you switch between Safe Mode (10% sampling), Balanced, or Detailed profiling with one click.</p>
<h4>WooCommerce Support</h4>
<p>Works with HPOS (Custom Order Tables) and Cart/Checkout Blocks. Tracks checkout complexity: payment gateways, shipping methods, coupons, and session size.</p>
<h4>Export Options</h4>
<p>CSV, JSON, and Markdown exports for reporting and analysis.</p>
<h4>Why Not a Page Speed Test?</h4>
<p>GTmetrix and PageSpeed measure frontend delivery. Speedix measures server-side PHP execution. They answer different questions. Use both.</p>
<h4>Privacy</h4>
<p>All data stays in your WordPress database. No external API calls, no tracking, no telemetry. GDPR compliant by design.</p>
<h4>100% Free</h4>
<p>Every feature is included. No pro version, no upsells.</p>

Code Profiler – WordPress Performance Profiling and Debugging Made Easy

Kudos to this amazing plugin. This was a dream, and now it's real!

The dream of many developer is now real


I am a developer of premium plugins, and I was able to discover a real bottleneck in our own plugin with this profiling tool. I use the PRO version for this, worth any money, and the breakdown by script file / method / execution time is great!



I don't know what magic is behind this (probably the calculation based on the backtrace), but it's awesome and doesn't require another PHP extension.


This is truly amazing!


This plugin is not much good without the pro upgrade. Seems unfair that I need to buy an annual subscription so I can run this plugin once or twice to fix issues and then never use it again. I understand the product  needs to be maintained but the fee is way too high for a single use. 


Pro is too expensive


This worked surprisingly well! Very useful settings. Much better than the old P3 profiler.  


Worked surprisingly well


I love Code Profiler, with it I can figure out which plugins have a poor performance and I can think about if this plugin is really that important to have or if I can just throw it out.



After having a specific problem with my site I posted a feature request in the forum, they were working on it quickly and the support was very good! I bought the premium version and I am impressed. I could lower the loading speed of some of my sites by 50-70% because Code Profiler helped me identify the problems.


I love it sooo much


Having looked at the screenshots before installing this plugin, I was dismayed to find that most of them refer to the premium version. 



I don't think it's acceptable that the screenshots attached to the free version of the plugin should be for the paid-for pro version - this is false advertising in my eyes. 


Deceptive advertising practices


Great support that goes far beyond supporting the plugin itself 🙏😊


Great support


Thanks, bought premium after free version showed a problem with WP Offload Media plugin. Pro version showed much more, glad I purchased.


Excelent


It's hard to believe you get all this for free. I can't even imagine what the paid version could offer more than the free. Thanks a lot.


Perfect

Very nice plugin and coded well!

So good
