Lab numbers are one Lighthouse run by Google on a throttled mid-range phone profile and vary by a few points between runs. “Real visitors” is the Chrome UX Report p75 over 28 days, for the URL or, when it has too little traffic, the whole site.
What this tool checks
One PageSpeed Insights run per URL, plus the Chrome UX Report where Google has field data.
Lighthouse performance score
The 0 to 100 speed score Google's own tools show, combining the main lab metrics.
Largest Contentful Paint
How long the biggest element on screen takes to appear, which visitors and Google judge speed on.
Cumulative Layout Shift
How much the page jumps around while loading, one of Google's three Core Web Vitals.
Total Blocking Time
How long JavaScript keeps the page too busy to respond to taps, measured in the lab.
First Contentful Paint
How long visitors stare at a blank page before the first text or image appears.
Speed Index
How quickly the visible part of the page fills in, so visitors see a complete screen early.
Real-user Largest Contentful Paint
How long the biggest element takes to appear for real Chrome users, against Google's 2.5 s target.
Real-user Interaction to Next Paint
How fast the page reacts to taps and clicks for real Chrome users, against Google's 200 ms target.
Real-user Cumulative Layout Shift
How much the page jumps around on real visitors' devices, against Google's 0.1 target.

How it works
Paste your list
One URL per line, up to 50. Pick mobile or desktop; each URL is measured once with that profile, the same Lighthouse run PageSpeed Insights shows.
Google measures each page
Four pages run at a time through Google's PageSpeed Insights API. Results appear in the table as they finish, and the run keeps going if you close the tab.
Sort, filter, export
Sort by score, LCP, TBT or CLS, filter the slow pages, and download everything as CSV. The run link stays valid for 30 days.
Lab scores vary by a few points between runs, and field data only exists for pages and sites with enough Chrome traffic. For a full report on one page with every check, use the speed test.
Questions
Is this really free?
Yes. getReport is funded by donations, not plans. The 50-URL daily limit exists because every URL uses one call of the free Google budget we share with everyone; there is no paid tier that lifts it.
Why do scores differ from PageSpeed Insights in my browser?
They come from the same Google API, but each Lighthouse run happens on a fresh machine with simulated throttling, so scores move a few points between runs even on the same page. Treat a difference of five or less as noise. Big gaps usually mean the page itself changed: an A/B test, a cookie banner, a personalised hero or a slow third-party script that only loaded one of the times. The real-visitor numbers (Chrome UX Report) are a 28-day average and do not move between runs at all, which is why Google ranks on those and not on the lab score.
What is the difference between the score and Core Web Vitals?
The score is one simulated visit on a slow phone. Core Web Vitals are what real Chrome users experienced over 28 days. Google ranks on Core Web Vitals; the score tells you what to fix.
Can I measure more than 50 URLs?
Not per day from one connection. For a whole site, run your 50 most important templates (home, category, product, article, landing pages); pages built from the same template score alike.
Do you store my results?
The run is kept for 30 days at its link so you can share it or come back to it. It is not listed publicly, and nothing about your visitors is collected.
