<p>MITS Profiler is a tool by <a href="https://mits.pl" rel="nofollow ugc">MITS</a> — a WordPress and WooCommerce agency based in Poland. It adds a diagnostic bar to any page by appending <code>?mits_prof=1</code> to the URL. It captures timing data from the moment PHP starts and presents it in a dark-themed panel at the bottom of the page — visible only to logged-in administrators.</p>
<p><strong>Tabs included:</strong></p>
<ul>
<li><strong>Timeline</strong> — absolute and relative timing between WordPress lifecycle hooks (plugins_loaded <span aria-hidden="true" class="wp-exclude-emoji">→</span> init <span aria-hidden="true" class="wp-exclude-emoji">→</span> wp_head <span aria-hidden="true" class="wp-exclude-emoji">→</span> wp_footer)</li>
<li><strong>Hooks</strong> — top 50 slowest action/filter hooks with total time and call count</li>
<li><strong>Options</strong> — most-queried WordPress options + full autoload audit with sizes</li>
<li><strong>Plugins</strong> — loaded PHP file sizes per plugin (proxy for load time)</li>
<li><strong>Assets</strong> — all enqueued scripts and styles, external ones highlighted</li>
<li><strong>HTTP</strong> — outgoing wp_remote_* requests with response time and status</li>
<li><strong>SQL</strong> — all database queries with slow-query highlighting (requires SAVEQUERIES)</li>
<li><strong>PHP</strong> — PHP version, OPcache status and hit rate, memory and execution limits</li>
</ul>
<p><strong>Key features:</strong></p>
<ul>
<li>Zero HTTP loopback — works behind Cloudflare, reverse proxies and strict firewall rules</li>
<li>No external dependencies or requests</li>
<li>Admin-only: the panel and all data are never shown to guests</li>
<li>Export to JSON or CSV for offline analysis</li>
<li>Works on front-end pages, WooCommerce pages, and WP Admin</li>
</ul>
<p><strong>SQL query logging</strong> requires adding the following to <code>wp-config.php</code>:</p>
<pre><code>define('SAVEQUERIES', true);
</code></pre>

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>
