Get complete Lighthouse scores, audit breakdowns, request waterfall, filmstrip, and prioritized recommendations — all from your browser. No setup required.
Why use this over CLI
Running Lighthouse locally means installing Node, configuring Chrome flags, and interpreting raw JSON. PageSpeed Insights gives you a score but hides the useful details. DebugUtils gives you the full picture with zero setup.
What you get
Performance, Accessibility, Best Practices, and SEO scores from Lighthouse v12 — the same engine Google uses to evaluate your site.
Every Lighthouse audit listed with pass/fail status, estimated savings, and priority ranking. No guessing which fixes matter most.
Frame-by-frame filmstrip and video recording of how your page loads, with TTFB, FCP, and LCP markers on the timeline.
See every network request in load order with full timing breakdown. Identify render-blocking scripts, slow third-party calls, and oversized assets instantly.
FAQ
Lighthouse is an open-source tool by Google that audits web pages for performance, accessibility, best practices, and SEO. It runs in a real browser, simulates a mobile device, and produces scores from 0-100 for each category along with specific, actionable recommendations.
A score of 90-100 is considered good (green), 50-89 needs improvement (orange), and below 50 is poor (red). Most production sites score between 40-70. DebugUtils shows you exactly which audits are dragging your score down and how much each fix is worth.
DebugUtils runs Lighthouse on dedicated infrastructure — your local machine's CPU, memory, and network don't affect results. You also get a request waterfall, filmstrip, video recording, and a shareable report URL that DevTools doesn't provide.
PageSpeed Insights shows scores and basic recommendations but lacks a request waterfall, visual filmstrip, video recording, and LCP element screenshot. DebugUtils gives you the complete diagnostic picture in one report, and every report has a shareable URL.
No. DebugUtils runs Lighthouse v12 on our servers using a real Chrome browser. Just paste your URL and get a full report in under 2 minutes — no CLI setup, no Node.js, no browser extensions.
