What is the Website Speed Test?
Enter any URL and this tool fetches it live, timing the full response, measuring Time to First Byte (TTFB), total page size and counting requests (images, scripts, stylesheets), then converts those into a 0-100 performance score with specific recommendations — the same core metrics a real visitor's browser experiences.
It's a real HTTP request against the live page, not a cached or simulated score: slow server response, oversized pages and too many render-blocking resources all show up directly in the numbers, with plain-language fixes underneath.
3 steps to your result
Open the tool and follow along. Nothing to install.
What you get
Measures actual response time and server Time to First Byte for the URL you enter.
Counts HTML, images, JavaScript, CSS and font requests separately so you know exactly what's heavy.
A single score, penalized for slow load time and large page size, to track progress over time.
Specific fixes like enabling compression, image optimization and caching, not generic advice.

Questions people ask
What is a good load time?
Under 2 seconds is considered good, under 1 second is excellent; Google's Core Web Vitals target Largest Contentful Paint under 2.5 seconds.
What is TTFB?
Time to First Byte — the delay between the request being sent and the first byte of the response arriving; under 200ms is considered ideal.
How is the performance score calculated?
It starts at 100 and is reduced for slow load time and large page size, giving a quick single number to track over time.
Does it test mobile and desktop separately?
Yes, choose the device before running the test since mobile results can differ meaningfully from desktop.
Is my data stored?
Test results are saved so you can see your test count and history; no login is required to run a test.
