Live per-element performance diagnosis: see exactly which images, scripts, CSS, and fonts slow down your page. Page Autopsy runs a full performance, SEO, and accessibility audit on any page - right from Chrome's side panel, with zero setup. One click gives you a 0-100 health score built from real browser data: Core Web Vitals (LCP, CLS, INP, FCP, TTFB), total page weight, request count, and DOM size - the same signals Google uses to judge your page. WHAT IT CHECKS - Core Web Vitals with CLS culprits and long-task attribution, not just the numbers - Every resource on the page - images, scripts, CSS, fonts - broken down by size, domain, and load time - Third-party weight tracked separately from your own code - Render-blocking scripts and stylesheets found in <head> - Cache & compression audit - flags resources served without gzip/brotli and estimates the savings - Duplicate request detection - Image audit - missing width/height (a top CLS cause), oversized images, missing lazy-load, outdated formats (JPEG/PNG that should be WebP/AVIF) - SEO scan - title, meta description, canonical tag, JSON-LD, preconnect hints - Accessibility scan - missing lang attribute, images without alt text, heading hierarchy gaps - Privacy scan - flags known analytics/ad trackers loaded on the page - Compare Before/After - save a baseline and see if your fixes actually moved the needle - One-click PDF export of the full report FREE VS PRO Free is not a trial - run unlimited analyses on unlimited pages, forever. Free shows the top items in every section (e.g. the biggest render-blocking files, the worst images). PRO unlocks the complete lists in every section plus the full Before/After comparison view. PRIVACY BY DESIGN Everything runs locally in your browser using the Performance and DOM APIs - no page content, URLs, or metrics are ever sent to a server. The only network call is to ExtensionPay to verify a PRO license, and only if you've purchased one. WHO IT'S FOR Developers debugging real-world performance regressions, freelancers auditing client sites before a handoff, and SEO/marketing folks who want a plain-language list of what to fix - without opening DevTools.
