Metricly: PageSpeed, SEO & Pixel Audit

Audit any page in seconds. Check PageSpeed scores, inspect SEO, and detect marketing pixels — right in your side panel

Every time you audit a page, you end up with 4-5 tabs open. A performance tester, a tag inspector, an SEO checker. You switch between them, copy-paste URLs, wait for results. Metricly puts it all in one place — one click, current page, instant results, right in a side panel that stays open as you work. Audit — run a full PageSpeed / Lighthouse-style audit without leaving the page. See scores for Performance, Accessibility, Best Practices, and SEO. Core Web Vitals and lab metrics included, with prioritized issues so you know what to fix first. Check an optional Agentic Browsing checklist to see how ready the page is for AI agents and crawlers. Switch between mobile and desktop strategies. Retest after fixes to see progress — each URL is cached separately. Audit history — every successful audit for the current site is saved locally, so you can look back at past results without re-running tests. SEO — check title, description, H1, canonical, robots, images, and metadata. Preview how the page will look when shared as a link in social apps and messengers, powered by Open Graph and Twitter Card tags. Pixels — spot common tracking pixels and analytics tags on the page — scripts, globals, and network signals. Grouped by category, with IDs you can copy in one click. Know what's firing before it becomes a problem. Metricly follows your system theme automatically — light or dark, no toggle needed. No DevTools. No extra tabs. No copy-pasting. Free. No account. Data stays in your browser.
