About
We built WebAnalyzer because every "free SEO audit" tool we tried buried real numbers behind a signup wall. This one doesn't — type a URL, get the same data Google uses to grade your site.
Core Web Vitals decide who gets seen
Google has been clear: page experience signals — how fast your content appears, how quickly it becomes interactive, and how stable the layout is while it loads — factor into search ranking. Most site owners only find out something is wrong after traffic drops.
WebAnalyzer puts those numbers in front of you instantly, in plain language, so you can catch problems before they cost you visibility.
Real Lighthouse data, run on demand
When you submit a URL, your browser sends a request directly to Google's PageSpeed Insights API, which runs a full Lighthouse audit against the live page and returns performance, SEO, accessibility and best-practices scores along with Core Web Vitals timings.
We don't proxy the request through our own servers, store the URLs you scan, or require an account to see results.
Three principles behind every feature
Free, always
Anyone should be able to check their site's health without a credit card or a "free trial" countdown.
Privacy-first
We don't ask for your email, store the URLs you scan, or track results back to you. See our Privacy Policy for details.
Plain language
Lighthouse reports can be dense. We translate scores and metrics into "good / needs work / poor" so anyone can act on them.
