See exactly what slows down your website and get actionable tips

Uptrends' free Website Speed Test gives you a snapshot of how your desktop or mobile users experience your webpage. You get everything you need to make smart performance-related decisions about your website and its content. Inspect your Google PageSpeed Insights score, recommended improvements, important page metrics, and page-load progression waterfall report. View important loading events with Google’s Core Web Vitals or W3C navigation timing metrics.

First, we spin-up a browser of your choice: Chrome, Firefox, Internet Explorer, or PhantomJS. As your page loads, the tool tracks every detail along the way. You can see how your website performance compares across different devices and networks from regions all around the world. You may also catch some misbehaving third-party content providers slowing down your site.

Compare page speed from Chrome, Firefox, and IE

Sure, Chrome users make up over 60 percent of the browsing public, but that still leaves millions of people using competing browsers. Firefox and IE have roughly 16 percent of the market share for desktop users. Make sure all of your other users have a great experience too.

Uptrends always uses the latest browser versions for your website speed tests. Most other speed-test services use older browser versions.

Check your web performance through different browsers, even the newest versions.

Inspect metrics and screenshots on how your page loads

With Google’s Core Web Vitals and W3C navigation timing metrics, you can view exactly when your webpage has performed important load events such as, First Contentful Paint (FCP) or Time to first byte (TTFB), for example.

The timeline of screenshots (filmstrip) is a new feature. While the page is loading, screenshots are taken when the page updates. You can view exactly how long it takes for your page to fully load with a visual timeline.

View Core Web Vitals and W3C metrics to see how you can improve, together with a timeline of screenshots of your loading page.

A fast website means better SEO

Do you know that a slower mobile experience can drop your website in Google’s rankings? Google evaluates your site’s mobile experience and uses your score when deciding where you rank for a keyword. You might have the best content, but your mobile speed can drag you down.

Optimize with Google PageSpeed Insights

Everyone loves a fast loading website; in fact, fast loading pages lead to higher conversions, reduced bounce rates, and better user retention. The speed test tool gives you optimization suggestions you need to focus your efforts and get the best results.

Share your website speed test results

Do you need to save your results for later or share them with someone else to see your test results? Use the Share results button and copy a shareable link to your clipboard. Send test result link to team members using your favorite communication channels.

Test your mobile website speed

Google ranks your page on its mobile speed, and mobile Internet users have surpassed desktop users. Select the size of the browser window we use for your test and view the resulting load times. We’ve got the most popular devices built right in for your testing.

Run tests through different mobile device viewports.

Use request and response headers to dig deep

Http request and response headers contain lots of useful information that help you understand specific checks. Make sure to inspect them for slow or not found elements.

Delve deep in to the details of loaded page elements with request and response headers.

Website speed from your users' locations

Even the most subtle changes within your site or the systems that support it can blow up your efforts to maintain a performant site. With Web Performance Monitoring, you can automate your checks and know the moment something causes site performance to slip.

Receive alerts when your site is slow

Uptrends' advanced alerting will let you know if it finds a discrepancy in your content, response size, response code, or authentication fails. Use SMS, email, voice, webhooks, or integrations with tools like PagerDuty and Slack.

Don’t forget about website uptime

HTTP/HTTPS monitors are Uptrends' most popular monitor types. Use Uptime Monitoring to watch your site’s uptime day in, day out. Performance and uptime monitoring together make sure your site is available and fast, and if it isn’t, you’ll know.
