Whether you are a site owner troubleshooting slow page load, a developer doing competitor research, or an agency auditing client sites, WP Performance Inspector gives you a complete technical SEO and speed audit without installing anything on the target site. Simply enter a URL below and get an in-depth WordPress performance report covering six critical dimensions: theme detection, plugin fingerprinting, on-page SEO analysis, server technology identification, caching layer inspection, and Google PageSpeed Insights scoring with Core Web Vitals (LCP, FID, CLS).
Measure real TTFB, LCP, FCP and CLS metrics for any WordPress site. Get a detailed Core Web Vitals report with Google PageSpeed Insights scores for both mobile and desktop.
Find out what WordPress theme and plugins a competitor site is using. Our fingerprint database identifies WooCommerce, Elementor, Yoast SEO, WP Rocket, and 40+ popular plugins.
Check meta title and description length, canonical URL, Open Graph tags, heading hierarchy, image alt text, structured data, and XML sitemap — all weighted for SEO impact.
Identify the web server type (Nginx/Apache/LiteSpeed), PHP version, SSL/TLS status, HSTS configuration, and security headers like CSP and X-Frame-Options.
Detect page caching solutions (WP Rocket, W3 Total Cache, LiteSpeed Cache), object cache (Redis/Memcached), CDN providers (Cloudflare, Sucuri), and browser caching policies.
Visualize every HTTP request in a waterfall timeline. Analyze total page size, requests by type (JS, CSS, images, fonts), and identify third-party script overhead.
