OctoPerf offers an easy-to-use SaaS load-testing solution because of its drag-and-drop system. You can easily design virtual users and simulate the complete journey of users browsing your application without any code at all. – John Turner, SeedProd LLC
2. LoadView
LoadView provides very reliable data, as it’s one of the few tools that go through real browsers to run tests — meaning it more accurately resembles real life. It’s also easily scalable and works on a pay-per-use model with no ongoing fees. – Nicolas Gremion, Free-eBooks.net
3. Google PageSpeed Insights
Google’s PageSpeed Insights gets data from real Chrome users. That means the speed test results are based on multiple users using different devices with different connection speeds. Combined with its optimization recommendation, this tool is the best load-testing tool out there. – Duran Inci, Optimum7
At my company, speed and the ability to perform under high call volumes are crucial. Our tech lead uses JMeter by Apache for its great information on statistics and metrics. It offers an organized user interface — providing information by endpoints — so you can easily detect improvements to your application. JMeter is customizable and allows for easy reproduction and various scenarios for load testing. – Cooper Harris, Klickly
5. GTmetrix
GTmetrix allows you to customize a number of different settings, including geographic location, browser type and connection speed. I like that it records a video of the site loading so you can see the first meaningful paint (when something is visually displayed). It also allows you to compare historical performance for free. – Kevin Getch, Webfor
6. LoadUI
LoadUI by SmartBear is a great tool for load testing application programming interfaces. It allows you to record traffic from mobile devices and replay and visualize the effects of unexpected traffic to your site. I like that you can visualize how your servers would handle different situations and plan accordingly. – Jared Atchison, WPForms
7. Load Impact
Load Impact is a cloud-based load-testing tool. Some of its most useful features include automated load testing, which can be integrated into continuous integration pipelines, and programmable load testing, which makes it ideal for testing e-commerce stores and other dynamic sites that have complex workflows. – Vik Patel, Future Hosting
This tool is an excellent all-around solution for load testing any web-based application. You can easily set up tests to meet your requirements, but what sets this apart, in my opinion, are the analytics. WebLOAD gives you all the information you need, identifies pinch points and suggests solutions. – Ismael Wrixen, FE International
9. Loader.io
Loader.io is a great tool to load test your app and/or website for many reasons, but one of the strongest reasons is that the results come in real time. Graphs and statistics can be shared anytime and anywhere, which helps our completely remote team. The real-time results help with communication and enable us to test our platform easy and efficiently. – Jared Brown, Hubstaff Talent
10. Direct User Testing
Nothing can test a load on an app like having people use it — which means you need to be offering potential users and customers some kind of incentive to download your app or check out your website. A contest, an affiliate program or free products or rewards are great ways to get users to flock to your app. Just make sure that you have e-commerce set up, so when they are ready to buy, they can. – Jason Criddle, Jason Criddle and Associates
11. Locust
Locust is an open-source load-testing tool that allows you to design user behavior with Python code and see how your system stands up to millions of users. It’s easy to use and has a nice web-based user interface. – Blair Williams, MemberPress
