How fast is your website, really?
We load your page the way a visitor would, check how it's built, and ask Google's Lighthouse for its scores. You get a plain list of what to fix first.
What we check
- Server responseHow long your server takes to send the first byte of the page.
- Page weightHow much HTML arrives, and whether it's compressed on the way.
- CachingWhether returning visitors' browsers are allowed to reuse files.
- What the page asks forScripts that block the first paint, images without lazy loading or modern formats.
- LighthouseGoogle's own lab scores for performance, SEO, accessibility and best practices, when Google's free service has capacity.
We fetch your page once from our server to run these checks and don't keep a copy. See our privacy policy.
