Enter a URL and see how fast your page really loads, on mobile and desktop. We pull real Google data when your site has enough traffic, fall back to a fresh lab test when it does not, and explain all of it in plain English with the top fixes. No login wall.
Free, no signup. Powered by Google PageSpeed Insights (Lighthouse + real-user Core Web Vitals). A full test takes 20 to 40 seconds.
Page speed is not a vanity number. It is one of the clearest predictors of whether a click turns into a phone call. This tool pulls the same data Google itself uses, real-user Core Web Vitals when your site has the traffic for it, a fresh Lighthouse lab test when it does not, and translates the whole thing into a plain-English verdict and the three fixes that would move the needle most.
Field data comes from Google's Chrome User Experience Report (CrUX): the actual experience of real Chrome visitors to your site over the last 28 days. It is the truest picture, but Google only publishes it for pages that get enough traffic. Most low-traffic local service sites do not have it yet. When that happens, a lot of tools quietly show lab numbers and let you assume they are real-world. We do not. Lab data is a single controlled test that Lighthouse runs on demand, and when field data is missing we say so clearly and show the lab result instead.
LCP (Largest Contentful Paint) is how long until the biggest thing on screen, usually your hero image or headline, finishes loading. Good is 2.5 seconds or under. INP (Interaction to Next Paint) is how quickly the page reacts when someone taps a button or link. Good is 200 milliseconds or under. CLS (Cumulative Layout Shift) measures how much the page jumps around as it loads, the annoying effect where you go to tap something and it moves. Good is 0.1 or under. Passing all three is a real ranking and conversion edge.
The mobile test simulates a mid-range phone on a throttled connection, which is how most of your customers actually find you. A site can feel instant on your office desktop and still be painfully slow on a phone in a parking lot, and that gap is exactly where local businesses lose calls and form fills. If you only fix one number, fix mobile.
GTmetrix gates mobile testing and multi-location runs behind PRO ($5 to $50 a month) and caps how many free tests you get. DebugBear and SpeedVitals are paid monitoring products. Ours is free, does both mobile and desktop, shows real Google field data when it exists and clearly-labeled lab data when it does not, and explains every number in plain English instead of a wall of jargon. No account, no credit card.
The Pro version tracks your speed continuously, alerts you when it regresses, and our team rebuilds the slow parts so your site stays fast.

Two different data sources come back. Field data is Google's Chrome User Experience Report: the experience of real Chrome visitors over the trailing 28 days, reported at the 75th percentile. Lab data is one Lighthouse test run on demand in a simulated environment, and the mobile run throttles both the connection and the CPU. The page labels which one you are looking at and never blends the two together.
The pass and fail thresholds are Google's published ones, not ours: LCP good at 2.5 seconds or under, INP at 200 milliseconds or under, CLS at 0.1 or under, TTFB at 800 milliseconds or under. The three top fixes are real Lighthouse audits that did not pass on your page, ranked by the millisecond savings Lighthouse itself estimates. Results are cached for an hour per URL and device.
Now the limits. It cannot see your competitors, your Search Console, or your analytics, and it cannot tell you what a speed fix will do to your rankings or your leads. If your page has no field data, which is normal on a lower-traffic local site, the tool falls back to whole-site data and labels it as such. If there is none of that either, you get lab numbers only. When Google's service is busy or rate limited, you get an error message, not an invented score. A broader check lives in the website report card, and the ranking side of the work sits under SEO.
Lab scores come from a single simulated Lighthouse run, so a few points of movement between runs is normal and reflects network and server conditions at that moment, not a change to your site. Results are also cached for an hour per URL and device, so an immediate re-run can hand back the same numbers rather than a fresh test. Field data does not move run to run at all. It updates on Google's schedule from a trailing 28-day window.
No. It measures loading performance on the one URL you enter and nothing else. It cannot see your keywords, your competitors, your Google Business Profile, or the words on the page, and speed is one signal among many. Nobody can tell you what a speed fix will do to your position or on what timeline, so treat the score as a build-quality check rather than a ranking forecast.
