The speed at which a website loads also decides how long we can be on it. In reality, for some of us, a website’s speed is more important than its appearance. Waiting longer for a (web)page to load can be incredibly inconvenient, and we often lose interest and move on to some other option as a result.
It hurts the company's reputation. Website speed should be at the top of your priority list if you want consumers to spend a long time checking out your merchandise and want your website to stay competitive in SEO rankings. And if you'd like to give your visitors a great experience.
Fortunately, software to optimize website speed can be found everywhere on the internet for free. These programs test a website's or application's speed to improve optimization. The program uses a variety of different metrics to perform this task.
Though there are many such resources to choose from, we've compiled a list of 15 of the best website speed checking tools. However, before we get into the list, let's go through some simple website speed terms so that you can grasp whatever the tools do and how they vary.
Let’s start with time to the first byte. It is a fundamental principle in web speed testing. It's a metric of how well a web server responds. When you type an address into the URL bar at the top of your tab, you're telling it to load the page. The time to first byte measures how easily it reacts to your message.
HTTP requests are made. The website and your device are connected via the hypertext transfer protocol when you send the message to the server. It is a collection of messages that travel from your computer to the server that hosts the website. The sluggish a website is, the more HTTP requests it makes. In this case, we must reduce the number of HTTP requests, like eliminating third-party plug-ins.
This, understandably, will cause the whole platform to slow down. Minimization is the process of reducing everything effectively. As the name suggests, it is the process of deleting all unnecessary elements from the website. The aim is to provide a bare-bones look for your website that contains all of the requisite details while being quick to load. The minifying program removes white lines and newline elements.
Website Speed Checking Softwares
KeyCDN provides a surprisingly fast and light output test with a wealth of information. You can pick from around 14 different locations, and you can keep your findings confidential or make them public. The reports produced by KeyCDN's Speed Test include a waterfall rundown and a summary of the webpage.
The files contain information, such as the number of HTTP requests created, the volume of the requested page, and the loading time, among many other items. The method is extremely sensitive and can also be used on a cell phone. KeyCDN provides this performance measurement platform, which builds on its experience as a real-time Content Delivery Network (CDN).
A CDN is a worldwide network of VPN systems and databases that provide high-speed networking and customer reliability. It is commonly used to ship apps and games, for example. The Speed Test from KeyCDN is HTTP/2 compatible, making it one of the more sophisticated website optimization tools available.
HTTP/2 is a newer version of HTTP that was released in 2015. TCP optimization is also available with the Speed Test. Transmission Control Protocol, or TCP, is a collection of protocols that regulate how data packets are transmitted over the internet. With 100 percent SSD (solid-state drive) coverage, KeyCDN's Speed Test can be used to test almost everything.
In addition to HTTP/2, the Speed Test involves origin shield, RESTful, real-time state, and immediate cleanup. KeyCDN's global network, based on IP Anycast and routing, has a low latency, which means it has good performance, scalability, and speed.
As previously said, the network is suitable for distributing games and apps, as well as advertisements, various types of websites, and content management systems (e.g., WordPress). The CDN's network of servers is designed to provide speed, compatibility, and scalability and ensure that page requests are routed to the closest point of presence at all times.
The user's proximity to the POP affects how quickly the website loads and how much data is lost. As a result, CDN aids in cost reduction and scalability. It's no wonder that their website performance platform is so good with benefits like these in the overall network.
The greatest part regarding Uptrends is that you can perform your speed test in one of over 35 different places. A domain population analysis and a waterfall breakdown are included in the final report. Waterfall maps show the overall influence of successively incorporated positive and negative qualities visually.
The domain classes article then delves further into the properties, categorizing them into various groups (e.g., social media, advertisements, third-party, etc.). The Waterfall Analysis allows you to pinpoint the aspects of your platform that are causing the most delays.
It examines HTTP headers for each feature. Rendering root cause analysis is a breeze. The Domain Groups review is versatile enough that you can choose which setup you want to use to examine your website.
Uptrends, for example, provides real-time browser analytics so that you can see what a normal user will see while browsing the site, including reports on bugs, uptimes, and average load time, all presented in an easy-to-understand way.
You will use the Full Page Check to see how each feature of a website affects load time. The Full Page Check includes third-party tracking, you can avoid third-party traffic slowing down the pages. User analytics, social media scripts, a consistency check of the Content Delivery Network, and an overview of video player embeds are also included in the Uptrends kit.
Uptrends offers personalized monitoring, which is usable on a timeline until all of the work is completed. It provides customized reports to understand where the website is struggling and helps in its optimization.
PerfTool is a fully free and open-source tool that began as a project on Github. PerfTool is a client-side program that gathers and shows information about a website. It produces reports that are very easy to interpret.
It is an npm bundle that displays details about web pages—Google PageSpeed Insights ranking, HTML bugs, information about how to correct output problems, CSS resources count, and more, according to its Github website.
PerfTool has the advantage of combining three data sets into one. There's Google PageSpeed Insights (discussed further down), which measures the site's basic results, Devperf, which provides data, and W3CJS, which validates HTML (checks the code to make sure it is correct).
PerfTool has over 200 different success metrics, including page numbers, tips, resource counts, loading times, and code errors. You will evaluate many pages simultaneously as soon as you get the website speed data. You may use this data to equate current output to previous results or to create a scoring benchmark.
You don't have to test each page individually with PerfTool if you're checking the whole platform at once. Devbridge also publishes a design resource to help users create, share and automatically produce the digital copy of their brands in regards to the Perftool. The previous clients of Devbridge include AON, Fitch Ratings, Mazak, and the Chicago Art Institute.
Dotcom-Monitor is unique in that it allows you to test from 25 different places and with 7 different browsers. You can also run all of the global tests at once. You can only run other software from each position independently with other apps. You may select individual reports for a waterfall breakdown review after the evaluation is completed.
A description, results, waterfall map, host analysis, and errors are all included in the reports. Any of the details is easily grasped thanks to the user-friendly GUI. Dotcom-Monitor's reports help you to see the elements of your website that are sluggish or absent. It also lets you check the loading time of all page elements by the browser.
The app is completely free and makes tests throughout cloud services, such as Amazon-US-East and domestic firewalls. Testing is possible. As Dotcom-Monitor continues to focus on new technologies, it appears like in the future the tool can do far better.
Currently, the reports enable you to track your site's success 24 hours a day, 7 days a week, with summaries by place. With the details given on the easy-to-read waterfall table, you can calculate the fastest and slowest 10% of components. As previously reported, the reports also include a breakdown by the host.
Almost everything is included; the first packet, the DNS, SSL, the connection, and the upgrade. The domain name system (DNS) is the phone book for the internet and allows you to see any device connected to it, while the primary authentication technology for the Internet is SSL or Secure Socket Layer that allows for the encryption of information when transmitted and received.
In addition, the tool allows you to search for errors and perform diagnostics. The network connectivity can be tested using a ping test that measures the efficiency of the network and reaction time. This allows you to detect errors even more quickly.
Dotcom-Monitor, headquartered in Minneapolis, Minnesota, is actively developing a new load checking application to provide consumers with even more features.
PageScoring is a minimalistic method that is convenient and easy to use. The mean loading time, domain searches, page sizes, installation times, redirection times, and connection times are shown in your reports. You will still see all of your parameters such as age elements, content, graphics, video, etc, as well as the time it took you to lead each one.
PageScoring is potentially your best bet if you want to review the success of your website quickly. These output instruments, including blogs, can be judged for how easily they function. According to studies, half of all website users expect a webpage to launch in 2 seconds or less, and 40% would leave it if it takes longer than 3 seconds to load.
Similarly, many users try to assess a website's results as soon as possible. Simply enter the domain name, and PageScoring will include a richly illustrated display of how long it took for the contents to load, as well as a commentary on different transmission processes.
It's a fantastic tool for tracking results in real-time and isolating data points for further interpretation. The Pagescoring user interface is the most basic on this list. All you see if you go to the page below is an address bar, 3 words, and a feedback tab. But don't be fooled by looks. Pagescoring is a useful method for evaluating the success of the website.
Varvy Pagespeed Optimization is a technology created by Patrick Sexton (the guy behind local listing service Moz Local) that offers reports in 5 parts.
Varvy is a great place to start if you're new to the world of webperf (website performance). The service's mobile optimization guide is one of its best features. After May 2016, when Google raised the frequency of the web-friendly rating signal, more focus has been put on mobile site usability. You should certainly go through the Varvy guide on mobile optimization to ensure that your site remains competitive in the smartphone market.
Another fast-and-easy way to check website speed is the Sucuri Load Time Tester. Sucuri offers the site a global ranking from A to F based on a worldwide network of hardware support and monitoring. It monitors how long a user has to log into the website and how long it takes to load a file.
It's important to note that using a CDN would almost certainly change the tool's functionality. The communication time is likely to be short when using a CDN. If your TTFB and total time aren't already big, you won't get much use out of this method in terms of efficiency.
Sucuri also offers web security and safety, backup software, and identification firewalls in addition to performance checking. The service appears to have reduced website load times by 70% on average.
Sucuri can connect with a user's existing CDN thanks to its existing CDN network, and a development team is always there to help you with any technical issues. Its servers, which are based on a global Anycast network, are very fast.
Sucuri supports HTTP/2, GZIP compression, an optimized setup, and intelligent caching. Sucuri's networks have advanced security as well, with a Security Operations Center that is available 24/7, 365 days a year to respond to any query.
Sucuri's Load Time Tester can support users to accelerate Caching with CDN and will defend users against DDoS, hacking, and assaults by brute force. Sucuri has the additional benefit of not requiring any installation. What you need is a DNS update, which their staff can assist you with.
YSlow is an open-source solution to Google's PageSpeed that is built on Yahoo website!'s optimization guidelines. The tools examine a website and report on how well it did in terms of Yahooguidelines. For YSlow to validate a site, it must go through 3 stages:
- To locate all the elements, the Document Object Model, the HTML framework, and other web codes are first used to construct a website.
- The knowledge about each element is then obtained.
- Finally, it takes the data and assigns ratings to each rule, culminating in an overall ranking.
The Yahoo! rules for high-performance websites are a set of 34 rules that influence the performance of web pages. The Exceptional Performance Team at Yahoo! produced them.
In its testing, YSlow employs 23 of these laws. The following are just a few:
- Reducing HTTP requests,
- Using the content delivery network,
- Decreasing DNS Lookups, and
- Supporting several browsers.
Google's PageSpeed Insights is one of the best metrics for evaluating website speed results. PageSpeed is fine, in particular, that all of the other resources on this list just display details from it.
The service assigns a score to your website ranging from 1 to 100, with something over 85 being considered fine. The tool is available in both desktop and tablet models. It also recommends the results of your site in its article (e.g., to change the picture).
PageSpeed measures the time to over-load that is, the time it takes for the upper part of the page to load and the time it takes to load a page. There is also a user experience guide on mobile posts that allows visitors to see scores, view settings, font sizes, and select target sizes, such as buttons and links. All of this information is presented in an appealing way by a new speed test feature inside the Think With Google service.
The PageSpeed algorithm obtains the domain URL twice, once from a desktop agent and once from a web agent. The outcome is a site rank out of 100, based on which sites are classified as "healthy," "requires work," or "bad." PageSpeed has a Chromium extension that enables you to monitor each page from the Developer Mode tab.
Overall, Google PageSpeed Insights provides a comprehensive view of the site's speed and what you can do to boost it. Since the tool is owned by Google, you should expect it to be improved on a regular basis.
One thing to remember: The calculator measures the relative effectiveness of the pages based on network-related page efficiency dimensions (HTML, internal and external resources, configuration). The exact indicator of your site's success is determined by the state of your local network and hardware.
Pingdom Speed Test is one of the most well-known website speed checker applications. There are 4 parts of the report generated by the Pingdom Speed Test:
- A waterfall map,
- A results score,
- Page analysis, and
The page analysis includes height, domain size, server queries as well as the content type of most requests. Pingdom tests the site in 4 different locations (2 in the United States, 1 in Australia, and Sweden each), and the reviews provide recommendations for how to develop the site. The findings break down both the page size and queries by content form and domain.
The service is free and provides visually appealing representations of load time for each page feature. The Page Analysis function is extremely thorough. It digs deep into the server response code to reveal information including site speed and fitness. There are almost no routing problems due to its presence in different locations. Accessibility, on the other hand, is not a problem. The HTTP service response codes are examined as part of the page review (indicate site speed, overall health).
In addition to the 4 research sites, there are 70 polling locations around the world that are open all year. Also with advanced functionality, Pingdom is cheap. They look at all aspects of the website, such as loading time and file sizes. You have complete control of how the data is sorted and filtered. You can not only see patterns in your performance history and share your results, but you can also see improvement metrics and advice.
When it comes to website success research, Pagelocity takes a unique approach. It, like other services, gives sites a score out of 100, but it also considers aspects like social media, SEO, money, and coding. You may also compare the rivals by tracking them.
All of this is possible even though you don't register. Anyways, once users register for a free account, you get more functionality. The Pagelocity results are available in 2 formats: code and resource. The code view shows the first-byte time as you go through HTTPs and Document Object Model in graphical form. The resources view displays which web elements account for the majority of the page’s size.
Pagelocity has reviewed almost 15,000 sites so far, according to their webpage, which is on the low end of the list. However, the comparative edge you will obtain by seeing how your rivals are doing is exclusive to this service. You will compare the comparative strengths and disadvantages using side-by-side metric analysis.
To make the site more appealing, the content of the website is evaluated using keywords, headings, and alternate picture text. The reports contain a resource rundown as well as HTML and CSS coding tips. This includes assistance with classes/Ids, identifiers, time to the first byte, and PageSpeed analysis, among other things.
There are a lot of glitzy data graphics in the papers, and there are a lot of success reviews.
The software is simple to use and responds quickly. It is compatible with a variety of computers and platforms. The app is intuitive and works on a variety of computers. A Romanian guy named Andy Gongea developed the Pagelocity webpage analysis tool.
Simply because it is Google, it appears twice on this page. Easy to use, but also with a lot of specialized features, is the built-in web analysis tool on Chrome's Dev Tools page. DevTools can be launched at any time by using F12 or Ctrl+Shift+I on Windows, Cmd+Opt+I on macOS. Chrome's Developer Apps are a suite of web authoring and debugging resources.
The most recent DevTools upgrades replace the old waterfall timeline with an aggregated data screen. You will see how much each factor costs in terms of time and which one is the most expensive. You may also segment the data by region, subdomain, and other types. The service displays the DOM material loading time as well as the overall loading time.
The network panel is where you go to see how well the network is doing. It helps you to log and track the behavior of the network and to access loading data for different elements of the whole website. You can filter and arrange the details displayed, as well as configure the panel to your liking. There's also the opportunity to see resources that are rendering-blocking (which we discussed above).
WebPageTest performs a consistency audit on a website in over 40 different sites, using 25 different browsers, plus smartphone browsers. These figures alone demonstrate how beneficial this website speed checker can be. Time to first byte, encoding, efficient CDN use, and caching, among other metrics, are used to rate websites on a scale of A to F.
An overview, information, content review and breakdown, screenshots, and performance evaluation are all included in the reports. When it comes to website accuracy reporting, WebPageTest uses a different approach. It gives a first and a repetitive view that all help to diagnose the first time the DNS search has been defined.
14. YELLOW LAB TOOLS
The tools are free and open-source, and they operate by submitting your website via a PhantomJS server. This enables it to gather metrics and statistics, which are then used to calculate the ranking. The information provided by the tool allows developers to fix mistakes and refine the site. Yellow Labs is free.
One of the most important online measurement tools is GTmetrix. It contains a thorough review of PageSpeed and YSlow metrics. It offers a final rating that varies from F to A. PageSpeed, YSlow, waterfall map, video, and history are the 5 parts of the GTmetrix performance study.
With just a free login, you can speed test your site in 7 different locations and select between Chrome and Firefox. The GTmetrix tools let you test various connections (cable, dial-up, etc.) for video replay and Adblock support.
The video replay feature allows you to see precisely when bottlenecks in your site's loading occur, and the Adblock feature allows you to see how your site performs when no ads are present. You have even more options with a free account.
You will see a full history of your site's load times by comparing PageSpeed and YSlow. Furthermore, there are several tracking options. You have the option of exporting your entire test history to a CSV format.
GTmetrix is one of the most used website performance tools, having analyzed over 222,000,000 pages to date. Every second, the number increases. PayPal, Spotify, GoDaddy, Nike, HP, NBC, and Nordstrom are among the firms that have collaborated with GTmetrix.
With GTmetrix, you can track the site on a regular, weekly, annual, or even hourly basis (with GTmetrix Pro). You must set up email alerts based on the fulfillment of certain conditions, such as the PageSpeed score falling below a certain level or the site load times exceeding a certain limit, and so on.
With 12 servers in Asia, South America, North America, Australia, and the United Kingdom, GTmetrix is one of the most reliable services on the list. It also allows you to review your results on an Android phone, giving you a visual representation of how your site loads.
This will assist you in determining the source of the lag. With a filmstrip-like perspective that lets you see page loading in a modern, interactive way, you can slow the process down to a fourth of its original speed and switch to big page load milestones.
GTmetrix's developer toolkit allows you to test pages on a variety of platforms of varying screen resolutions. For a commonly used alternative, you can generate a collection of presets. GTmetrix offers tracking, visualization, zoom and pan, annotation, and warnings as a whole. The Pro version contains 15, 50, and 150 US$ of bronze, silver, and gold per month.
Improvements to Be Made
There are a few things to bear in mind until you've decided which method to use. For starters, running either of them can trigger a delay in the first DNS lookup. The Domain Name System (DNS) is essentially a registry of all machines and gadgets on a network's names (such as the Internet). When a specific machine connects to the internet, the DNS is used, and looking up the interface takes time.
The amount of time you spend can be determined by the method you're using. This is why, to get a better understanding of your website or application's speed, you can run several tests and combine the results. It's also a good idea to monitor the site on a regular basis and set some kind of goal for yourself over time. You can monitor the progress of your website over time and make changes if needed.
Almost every tool on this list will tell you what you need to do to increase your website speed. It's as simple as implementing any of these (often simple) recommendations until you figure out why the website isn't running at its best.
Compressing big images, reducing HTTP requests, switching to a quicker web server, caching data, and writing more powerful code are all examples of this.
You will also want to test the website speed with a variety of Chrome plugins for added ease. Hence, these can be launched directly from your browser. It is also safe though, as a big part of all page queries is submitted from mobile, to use cell speed tests on the website.
Chrome Developer Tools also allows you to simulate possible speeds on a variety of mobile devices and at various connection speeds.
Fun fact: 3G connections account for 70% of all connections globally, and this trend will extend until 2020.
The most critical thing, regardless of which platform you use, is to keep up with all of the new trends. The first thing you can consider if you want your platform to be successful is how quickly it loads. Even the tiniest lag will result in a slew of missed views and visits.
