4 min read

Speed can make or break your website. That’s why web developers, marketers, and IT departments alike are paying attention to website speed testing tools. Improving your webpage loading speed can have a dramatic effect on the overall success of your site.

Here are 10 website speed test tools

1. GTmetrix

GTmetrix goes into great detail as it checks both PageSpeed and YSlow metrics, assigning your site a grade from F to A. It’s reports are divided into five different sections including PageSpeed, YSlow, waterfall breakdown, video, and history.

With a free registration, you can test from seven different locations. They also let you choose the browser, Chrome vs Firefox. You can test and compare website performance against various connection types (like Cable vs dial-up) to see how it affects your page loads. Other advanced features include a video playback to analyze where your bottleneck is occurring and also the ability to run Adblock plus. With ads disabled you can see how they affect the loading of your site.

2. WebPageTest

Our next entry on the list probably isn’t going to win any web design awards in the near future. WebPageTest, however, is one of the more reliable and trusted website speed testing tools available to users today. The primary strengths of WebPageTest include:

  • Users can create custom settings for each run of WebPageTest they initiate.
  • With all of these options, WebPageTest can be configured to use a wide variety of different locations and different web browser options. It’s possible your website might be slow on Google Chrome but lighting quick on Firefox, and if that’s the case, WebPageTest will let you know.
  • Users can also order WebPageTest to perform multiple runs. This can give you a sense as to whether your website’s page speed is performing consistently.

3. Pingdom Speed Test

Pingdom is probably one of the more well-known website speed test tools. Their reports are divided into four different sections which include a waterfall breakdown, performance grade, page analysis, and history.

The page analysis offers a great overview with additional information such as a size analysis, size per domain (you can easily compare your CDN assets size vs your domain), the number of requests per domain, and what type of content had the most requests.

Pingdom’s speed test tool also allows you to test your website’s speed from four main locations including:

Dallas, Texas, USA,
Melbourne, Australia
San Jose, California, USA
Stockholm, Sweden

The results of a Pingdom speed test provide you with performance insights, similar to Google PagesSpeed Insights, which outline where can you make improvements. The results also break down the page size by content type, page size by domain, requests by content type, and requests by domain.

4. KeyCDN Website Speed Test

KeyCDN built a fast and lightweight website speed test tool which you can use to get detailed insights on how your website performs. If offers 14 locations to choose from around the globe, and you have the option of making your test results private or public. The test includes a waterfall breakdown and a visual website preview at the bottom. You can quickly see how many HTTP requests were made, the full size of the page requested, and the load time.

It is also one of the only tools besides PageSpeed that is responsive and works great on mobile devices.

5. Varvy Pagespeed Optimization

Varvy Pagespeed Optimization is a tool developed and maintained by Patrick Sexton, who also created GetListed.org, which is now known as Moz Local.

The reports are broken into 5 different sections including a resource diagram, css delivery, javascript usage, page speed issues found, and services used. This tool uses more of a graphical representation of what could be fixed on your site, such as render blocking.

Patrick does a great job of also including documentation on how to further optimize your site with tutorials on critical render path, leveraging browser caching, defer loading javascript, and much more.

6. dotcom-monitor

dotcom-monitor offers 23 different locations and seven different browsers in which you can run your website speed test. Their unique feature is that you can run all geographical tests simultaneously. This can save you a lot of time, as every other tool you have to run them individually per location. You can then click into each individual report and or waterfall breakdown.

Their reports are divided into five different sections which include a summary, performance, waterfall chart (breakdown), host, and errors.

7. Dareboost

At first glance, the Dareboost webpage speed tester looks like all the others. In some ways, that’s good. It’s easy to put in your web address and choose a test location and start your test.

But Dareboost is also a little tricky. If you’ve already used the service once, you’ll need to sign up for a free account in order to keep using it. It’s usually worth it; but don’t be shocked if you swing back to Dareboost and have to create a username. That said, Dareboost definitely offers some interesting features:

A great breakdown of data into visual representations. Once you know what all the data means (Dareboost provides some generous and easy to read explanations), you can really see your progress.
Dareboost also features video breakdown of your loading process. It might sound a little silly, but it can be quite useful to actually see what your user is seeing as your webpage loads. You can slow even slow down the video to really see the load order (or the rendering order).

8. Yellow Lab Tools

Yellow Lab Tools is a newer web performance and front-end quality testing tool. This tool gives you a lot of information and some unique features not seen in other tools such as a view of when JavaScript interactions with the DOM during the loading of the page and other code validation issues. Get a global score based on the following qualifiers.

  • Page weight
  • Requests
  • DOM
  • Bad Javascript
  • Bad CSS
  • Server Config

9. Pagelocity

The Pagelocity tool offers another unique approach when it comes to a website speed test. It gives you a total score out of 100, consisting of factors such as social, SEO, resources, and code. The tool also offers the ability to track your competitors. You can signup for a free account to benefit from the additional features. The code view is especially unique as it will show you if your site is running over HTTPS, what your TTFB is, and a graphical interface of your DOM elements with a bar chart.

10. PerfTool

PerfTool is an open source client side performance tool project, hosted on Github. It collects various information about your website and displays it in an easy-to-digest manner on a reports page. It combines three data sources in one, PageSpeed Insights, devperf, and W3CJS. In total it gives you over 200 different performance indicators.

One big advantage with the PerfTool is that you can run multiple pages tests at the same time for Google PageSpeed Insights report. Then, compare website performance results from previous tests, set score threshold and get detailed report about your tests. This can actually save you a lot of time if you are benchmarking your entire site’s web performance, as you don’t have to test your pages one by one
