Top 5 Best Online Load Testing Tools

Table of Contents

In this article, we will go through our favourite features of each of these cloud-based load testing tools (see also our article “Top 10 Load testing Tools“), while in the end you will find a parameterized comparison of all of them in one table.

1. Boomq.io

We proudly give Boomq.io the first place in this list for the ease of use, ability to compare the results of the tests, and handy trend reports that help to localize the bottlenecks really quickly. It allows running complex tests in the cloud to anyone interested in load testing. 

To use Boomq, you don’t have to be a load testing engineer or even hire one. This new-generation tool is able to import load profile data from Google Analytics, Yandex.Metrica, and other sources. All you have to do is log in, and then Boomq.io retrieves your statistical information and lets you run load tests without any coding or other engineering. The ease of use is matchless.

But it does not mean that Boomq is for non-specialists only. Of course, you may customize the tests if you want to, or run your own JMeter scenarios. Developers and performance engineers will find boomq.io handy for conducting performance tests in the cloud, too. They can use a full suite of testing tools, such as HAR/Insomnia import, request definition, parameterization and correlation running in the cloud as SaaS service. You can also manage and reuse tests, centralize the assets, compare the results between them, see trends across time and share results and reports. No need to worry about infrastructure deployment, though. 

Boomq’s no-commitment policy is another rare feature: no credit card is required for a free version. Just start testing right away.

Pros

    • Easy-to-use web portal for all your performance testing needs
    • Ability to define emulated user actions without coding
    • Easily build your profile based on statistics from Google Analytics, Yandex.Metrika, etc
    • Record your tests in any browser, such as Chrome or Firefox, via HAR import
    • Import your requests from functional testing tools, such as Insomnia or Postman
    • JMeter plugin to easily upload your work into cloud and support your existing workflows
    • Easily shareable test results through a web report
    • Detailed and visual test-to-test comparison
    • Easy to read SLAs immediately indicating the test status
    • Trending of the multiple test results, giving a high-level overview of the multiple SLAs over multiple test-runs
    • Ability to run the tests and receive results through a modern API, which could be easily called from your favorite CI/CD conveyor (GitHub. Gitlab, CircleCI etc) or any other system

Cons

    • At this point, Boomq.io only supports HTTP(-s)-based protocols

2. BlazeMeter

BlazeMeter is a platform for fully-functional web testing and load testing the capabilities of desktop or mobile applications. BlazeMeter was created on the basis of open source code, and is fully compatible with Apache JMeter. 

Its intuitive interface provides all the features necessary for load testing. An unbeatable advantage is a huge list of supported script formats allows you to create tests without having to convert files. Another very convenient feature is an extension for Chrome, which allows recording scripts and uploading them in JMX/JSON/YAML in a couple of clicks. 

The service also provides access to many advanced features, such as setting uo mock services, application performance monitoring (APM), real-time reporting, automated reports emailing, distributed testing, and integration with developer tools for continuous integration (CI). If your organization is already using Apache JMeter, you will like BlazeMeter, too, although it can be somewhat expensive for user load volumes exceeding 1000 users.

Pros

    • Integration with CI tools
    • Creating tests using scripts of almost any format
    • Scheduled launch of tests and sending test results by email
    • Comparison of test results
    • A large selection of instances with different locations
    • Setting up Mock Services directly on the platform
    • A large selection of APM integrations

Cons

    • Very basic and superficial reporting
    • Expensive for user load volumes exceeding 1000 users
    • Lack of a concise editor

3. OctoPerf

OctoPerf is a commercial full-featured SaaS platform for load testing of any HTTP-based website or mobile application. It was created using proven open source technologies based on Apache JMeter. To create a test, all you need to do is to import a list of URLs, REST API, a HAR/JMX script or a Postman collection. The built-in editor provides tools for correlation and parameterization of the newly recorded script. 

OctoPerf allows you to use public instances in a public cloud using Amazon Web Services (AWS), Digital Ocean or Microsoft Azure. The possibility to configure Service Level Agreement (SLA), application performance monitoring (APM), a detailed report on each transaction, integration with developer tools for continuous integration (CI) are just some of the features that can be useful to anyone who wants to run load testing.

Pros

    • Full-featured built-in script editor
    • Setting up SLA
    • Ability to create custom metrics
    • Detailed report on each transaction
    • A large selection of instances with different locations
    • Browser-based load testing by Selenium WebDriver
    • A large selection of APM integrations

Cons

5. K6 Cloud

K6 Cloud is a commercial SaaS tool that is a perfect addition to K6 OSS and provides ease of use and convenience in performance and load testing. The test builder with a graphic user interface allows you to quickly and easily create tests. If necessary, you can write your own script in JS, or use an extension for Chrome with an upload in HAR format. The test is run in various locations in the public cloud using Amazon Web Services (AWS). 

Due to some advanced features of the platform, it is possible to set thresholds to confirm Service Level Objectives (SLO) and run scheduled tests, configure application performance monitoring (APM) and integrate with developer tools, such as Jenkins, GitLab, Azure Pipelines, etc. You can also run cloud tests from the command line if you have k6 Open Source installed.
