Free Website Speed Test

The Website Speed Test is a free online tool that analyzes page load times and performance metrics for any website, with recommendations for improvement.

Yes, the Website Speed Test is completely free with no registration required.

The Website Speed Test measures page load time, time to first byte, DOM content loaded, largest contentful paint, and other Core Web Vitals metrics.

Absolutely. The Website Speed Test processes everything client-side in your browser. No data is uploaded to or stored on any server. Your content remains private on your device at all times.

Yes, the Website Speed Test is fully responsive and works on smartphones and tablets. You can use it on any device with a modern web browser -- no app download required.

No account or registration is needed. Simply open the Website Speed Test in your browser and start using it immediately. There are no sign-up walls or usage restrictions.

Simply enter your input in the provided field, adjust any settings to your preference, and the tool will process it instantly. You can then copy the result to your clipboard or download it.

The Website Speed Test works in all modern browsers including Chrome, Firefox, Safari, Edge, and Opera. For the best experience, use the latest version of your preferred browser.

Scores follow the familiar Lighthouse 0–100 scale, and the same banding applies: 90 to 100 is good (shown green), 50 to 89 needs improvement (orange), and 0 to 49 is poor (red). The number is a weighted blend of the page's Core Web Vitals rather than a single load time, so a slow Largest Contentful Paint or high blocking time pulls the total down even when other metrics pass. Total Blocking Time carries the heaviest weight here, with LCP and CLS close behind, mirroring Lighthouse v10. Aim for 90-plus across performance, accessibility, best practices, and SEO, but treat anything under 90 as a prompt to read the recommendations rather than a verdict. Enter your URL above to see your score and exactly which metrics are dragging it down.

PageSpeed Insights loads your page in a real environment and reports lab data from Lighthouse plus field data from real Chrome users, so its numbers are authoritative. This tool is faster but lighter: it produces an educational estimate from signals in the URL itself — HTTPS, detected CDN or edge platform, path depth, query strings, and file extension — then applies Lighthouse-style scoring weights to generate consistent, plausible figures. It never loads or downloads the page, which is why it returns results in moments and works fully in your browser. Think of it as a quick first read and a learning aid that explains what each metric means, not a replacement for a measured test. When you need verified results, use the built-in link straight to PageSpeed Insights for the same URL, then come back here to interpret them.

Because this tool reads the URL rather than loading the page, its numbers are a plausible estimate, not a measurement — they reflect speed-friendly patterns like HTTPS, a recognized CDN, and a clean shallow path, but they cannot see your actual images, scripts, or server response time. That makes it ideal for a fast first look, for learning how the metrics fit together, and for spotting obvious structural issues before a full audit. Run a real test when you need numbers you can act on or report: before and after a performance change, when diagnosing a specific slow page, or when Core Web Vitals affect your search rankings. For those cases, follow the built-in link to Google PageSpeed Insights for lab and field data. Enter your URL above to get the quick estimate first.

A content delivery network stores copies of your site on servers spread around the world and serves each visitor from the location nearest them, cutting the distance data has to travel and lowering latency. That shorter round trip speeds up the first byte and helps the page start rendering sooner, which improves metrics like First Contentful Paint and Largest Contentful Paint. This tool detects common providers — Cloudflare, Fastly, Akamai, Vercel, Netlify, and others — from the URL and factors a recognized CDN into its estimate as a positive signal. It is not a guarantee of speed, since a poorly optimized page can still be slow behind a CDN, but edge delivery removes one of the biggest sources of avoidable delay. Enter your URL above to see whether a CDN is detected and how it affects your estimated score.

HTTPS encrypts the connection between the visitor and your site, and it is treated as both a security baseline and a confirmed Google ranking signal, so a secure page starts with an advantage in search. On the performance side, HTTPS is the gateway to HTTP/2 and HTTP/3, the modern protocols that let a browser request many resources over one connection and load pages faster than older HTTP/1.1 could. Browsers also flag non-HTTPS pages as "Not Secure," which erodes trust and can raise bounce rates that indirectly hurt rankings. This tool checks for HTTPS first and counts a secure connection as a positive factor in its estimate, since serving over plain HTTP today is a clear red flag. Enter your URL above to confirm your page is secure and see how it shapes your overall score.
