We load your page in Google's lab and pull 28 days of real-visitor data from Chrome — then tell you, in plain words, what's slowing it down.

Private by design
No accounts, no cookies, no tracking. NuuMa doesn't store what you check. To run the tests, the address you enter goes directly from your browser to the public services named above. The only thing kept is a small daily counter in your own browser that keeps these tools free for everyone.
Questions, answered plainly
What are Core Web Vitals?
Three measures Google uses to judge real-world page experience: Largest Contentful Paint for loading (good at 2.5 seconds or less), Interaction to Next Paint for responsiveness (good at 200 milliseconds or less) and Cumulative Layout Shift for visual stability (good at 0.1 or less).
Why do lab and real-visitor results differ?
The lab test is one load on an emulated phone and network. Real-visitor data is the 75th percentile of actual Chrome users over 28 days, across every device and connection.
Why does my score change between tests?
Network conditions, server load and third-party scripts vary from run to run. A few points of difference is normal — watch the trend, not a single number.
