Overview
One-click performance audit. Core Web Vitals (LCP, FID, CLS), load timeline & suggestions.
Is your website costing you users? Slow load times silently kill conversions, damage SEO rankings, and drive customers to competitors. Website Speed Auditor gives you a complete performance picture in one click — no setup, no accounts, no external servers. ▸ WHAT YOU GET Performance Score: An overall 0–100 score based on real browser metrics, calculated instantly. Core Web Vitals: Measure the metrics Google uses to rank your site — Largest Contentful Paint (LCP), First Input Delay (FID), Cumulative Layout Shift (CLS), and Time to First Byte (TTFB). Each vital is color-coded: green (good), orange (needs improvement), or red (poor). Load Timeline: See exactly where time is spent — DNS lookup, TCP connection, server response, content download, DOM parsing, and full load. A visual bar chart makes bottlenecks obvious. Actionable Suggestions: Get prioritized recommendations based on your actual metrics. High-impact issues like slow server response or unoptimized images are flagged first. ▸ HOW IT WORKS 1. Navigate to any web page. 2. Click the extension icon. 3. Press "Run Speed Audit." 4. See your score, vitals, timeline, and suggestions in seconds. That's it. No configuration, no waiting. ▸ PRIVACY BY DESIGN Website Speed Auditor runs entirely inside your browser. All performance data is collected using the Navigation Timing API and PerformanceObserver — standard browser APIs that require no external requests. • No data is sent to external servers. • No analytics or tracking scripts. • No browsing history access. • No cookies or personal data collected. • No account or sign-up required. This extension requests only two permissions — activeTab and scripting — the minimum needed to measure performance on the current page when you explicitly click the extension. ▸ WHO IS THIS FOR • Startup founders who need fast products to retain users • Development teams benchmarking performance each sprint • Marketing professionals ensuring landing pages convert • Agencies auditing client websites • E-commerce teams where every millisecond matters • Freelancers offering performance consulting ▸ ABOUT LIVEUPX Liveupx helps teams build faster, more reliable software systems.
