Overview

The Performance Debugger for Magento 2 is a production-grade frontend profiler for Magento 2 and Adobe Commerce that surfaces per-page render time, slow database queries, plugins, observers, and memory usage in a floating storefront toolbar. It turns "the site feels slow" into a prioritized fix list with severity scores and estimated millisecond savings.

The floating toolbar runs on every storefront page (gated by admin IP allowlist so it never leaks to real customers) and shows a per-collector breakdown: block render, observers, plugins, layout XML, DI resolution, queries, memory. The N+1 detector and duplicate query roll-up catch the worst offenders fast - a single product page firing 200 redundant SELECTs lights up in the toolbar instantly. Each issue ships with a severity score and a suggested fix so engineers can prioritize by milliseconds saved instead of gut feel.

The Performance Debugger for Magento 2 also exports XLSX and PDF reports for stakeholder reviews or ticket attachments, works on both Hyva and Luma without theme changes, and installs cleanly via Composer with zero core hacks. Tested on Magento 2.4.4 to 2.4.9 with PHP 8.1 - 8.4. Free forever, MIT-style open source, source included so you can read, modify, or extend any collector.

Best for:

Stores fighting for green Core Web Vitals and sub-2.5 s LCP on real PDPs
Engineering teams hunting N+1 query patterns introduced by third-party extensions
