What’s inside

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.

How to fix it

We don’t just flag problems. Every suggestion ships with copy-paste code.

Compare & history

Re-test and get a before/after diff; track regressions over time.

Scheduled monitoring

Watch a URL on a schedule; get a webhook or email alert when a metric crosses a threshold.

What sets us apart

GTmetrix shows the problem. We help you fix it.

  • Not tied to Lighthouse: our own engine, our own rules.
  • Copy-paste code/config for every suggestion (nginx, HTML, Next.js…).
  • Optional AI summary: what to fix first, why, and how.
  • A generous free tier and no-signup trials.

Where our engine and our report actually differ from GTmetrix and Google PageSpeed Insights, including the row we lose.

AuditSpeedThis is us GTmetrixLighthouse based PageSpeed InsightsGoogle Lighthouse
Measurement engine Our own Chromium, driven through raw CDP. Our rules, so our scores stay put. Lighthouse, so the scores move when Lighthouse changes. Lighthouse, the same dependency.
What you get after the diagnosis A copy-paste fix per finding: nginx config, HTML, framework snippets. A description of the problem. A description of the problem.
Video and filmstrip Both, free accounts included. Filmstrip yes, video depends on the plan. Screenshot filmstrip only, no video.
Comparing reports Up to four reports at once, and across different domains. Report comparison depends on the plan. One report at a time.
Scheduled monitoring From the free account up, with webhook and email alerts. Monitoring with alerts, inside its own plan limits. Not part of the product.
API access Included from the free tier, with your own key. Metered by API credits. Free public API.
Free tier 15 scans a day with an account, and scanning with no account at all. Free account with a daily limit. Free, with no limit worth worrying about.
Real-user field data (CrUX) No. We measure in a lab browser, not in your visitors’ browsers. Lab measurements only. Yes, real Chrome User Experience Report data.
Price of the first paid tier $5 a month. More. Free.

PageSpeed Insights is free and shows real field data from the Chrome User Experience Report, which we do not have. If that is the number you need, go and use it. Knowing what to change in your code afterwards is our half of the job. The two competitor columns describe their published plans, which they can change at any time: check their own pricing pages for the current terms.

Good to know

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 3 scans per hour and 5 per day from one test location, with the full report: scores, Web Vitals, waterfall and the fixes. Video and filmstrip are the part that needs an account.

What does a free account add?

It lifts you to 15 scans a day from two locations, unlocks video and filmstrip (3 a day), and adds test history, a daily monitor and an API key. Still free, still no card.

Why is video optional now?

Recording the page and building the filmstrip costs far more capacity than a plain scan, so it is a checkbox in advanced settings instead of something every test pays for. Turn it on when you actually need to watch the load.

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 the paid plans?

No. Starter and Pro are monthly subscriptions you can cancel with one click in your account, with no contract and no cancellation fee. Cancelling takes effect at the end of the month you already paid for, and after that your account returns to Free.
