Tools
Lighthouse-backed diagnostics for every layer of your WordPress stack.
17 tools
CLS Diagnostics
Find the layout shift culprits — unsized images, late-injected elements, and FOIT-driven text reflow.
Run the toolCache Analysis
Inspect cache TTLs, stale-while-revalidate directives, Vary headers, and query-string caching patterns across all resources.
Run the toolDOM Analysis
Measure DOM depth, total element count, and the heaviest subtrees. Flags pages that exceed browser rendering thresholds.
Run the toolDependencies
Map the full dependency tree of any page — scripts, CSS, fonts, images, and the global-variable relationships between them. Filter to the critical rendering path.
Run the toolFont Audit
Analyse web font delivery — font-display values, self-hosted vs external, preload coverage, and file size (subset signal).
Run the toolHead Audit
Audit every element in <head> — render-blocking scripts and stylesheets, font-display, CSP placement, and resource hints.
Run the toolImage Diagnostics
Detect oversized, uncompressed, unsized, and poorly loaded images. Surfaces SVG opportunities and decoding attribute gaps.
Run the toolImage Optimization
Lighthouse-backed audit for format, sizing, and compression savings across all images.
Run the toolLCP Diagnostics
Identify the LCP element, its render delay, resource load chain, and fetch priority optimisation opportunities.
Run the toolLong Tasks
Detect tasks blocking the main thread for more than 50ms — the root cause of high TBT and poor INP.
Run the toolNetwork Audit
Check compression (gzip/brotli), HTTP/2 & HTTP/3 protocol, redirect chains, SWR directives, and Vary header patterns.
Run the toolResource Hints
Audit preload, prefetch, preconnect, and dns-prefetch hints. Surfaces missing preloads for blocking CSS, fonts, and LCP images.
Run the toolScripts Diagnostics
Audit every script on the page — blocking vs deferred vs async, inline candidates, minification gaps, and first- vs third-party split.
Run the toolTTFB Analysis
Page TTFB breakdown with connection stack, plus per-resource TTFB analysis with averages by type.
Run the toolThird Party
Map every third-party by weight and main-thread time. Flags self-hostable scripts and detects service worker registration.
Run the toolVideo & Media Audit
Detect video elements missing poster or muted attributes, animated GIFs to replace with video, and LQIP usage.
Run the toolWordPress Audit
WordPress-specific signals: emoji script, Heartbeat API, REST API caching, Speculation Rules, and service worker status.
