Scores, waterfall, filmstrip, and copy-paste code to fix each issue.
Everything you expect from a speed tool
Plus fix suggestions most tools skip, and our own measurement engine.
Our own Chromium engine
No Lighthouse. Real browser, raw CDP: more transparent, more flexible.
Web Vitals + 24 audits
LCP, TBT, CLS, Speed Index, TTFB… with a clear A–F grade.
Waterfall · Filmstrip · Video
A timeline for every request, a frame-by-frame strip, and full video.

Frequently asked questions
Do you use Lighthouse?
No. Our engine is built on Playwright plus raw Chrome DevTools Protocol, so we can measure things Lighthouse doesn’t and apply our own rules.
Do I need an account to test?
No. Without an account you get 5 scans per hour and 10 per day, with the full report. Sign up free for more, plus history and monitoring.
How realistic are the results?
We measure in a real Chromium browser with the device and connection profile you choose. For steadier numbers, take a multi-run median in advanced settings.
Is there a commitment on Pro?
No. Pro is a single 30-day payment: no auto-renewal, no stored card. When it ends, your account returns to Free.
