To produce high-quality software, you must ensure that your software is reliable, stable, scalable, secure, maintainable, and efficient. Software testing is an integral part of the Software Development Life Cycle (SDLC) to improve its quality and enhance the features. Software testing helps identify bugs and performance issues to rectify them before they impact the end-user.

Testing can be done manually or automated. Manual testing involves testers acting as an end-user to try out all the software’s functionalities and features according to a test plan, and defects are identified in the process. However, it is time-consuming and very limited in identifying bugs and performance issues. Automated testing makes use of scripts and tools to reduce testing time and increase issue identification capabilities. Automated testing is beneficial in performance testing, such as load testing and regression testing.

While there are many tools available for testing your website or applications, SoapUI and JMeter are used widely. Which one is the best among the two? Well, that depends on your testing and software quality goals. But we will talk about the differences between the two, so you can make an informed decision.


Introduction:  SoapUI and JMeter



SoapUI is an open-source testing tool focusing on API  and webservices Quality Assurance (QA). It was first made available in 2005 and is widely used by developers working on SOAP and REST APIs. It can be used for functional testing as well as performance testing (load testing). It also has a paid version, extending the capabilities of the open-source version. The following are some main features provided by SoapUI:

  • Functional testing of APIs and webservices
  • Simulation of webservices
  • Security testing and QA
  • Load testing


The following are the applications and protocols supported by SoapUI:

  • SOAP
  • REST
  • HTTP/S
  • JMS
  • AMF
  • JDBC
  • OAuth 1.0 and OAuth 2.0



JMeter is an open-source performance testing tool offered by Apache Software Foundation whose primary objective is to perform load testing. However, it can also be used for functional testing, such as unit testing. It was first made available in 1998 and comes with enterprise-grade load testing capabilities. JMeter functionalities can be easily extended because of its plugin-based architecture. The following are the applications and protocols supported by JMeter –

  • HTTP/HTTPS and web applications
  • JDBC database connections,
  • FTP (File Transfer Protocol)
  • Mail (SMTP, POP3, IMAP)


SoapUI vs. JMeter

Let’s get into more details and talk about different aspects of both tools.



SoapUI is used mainly for functional testing to identify bugs and defects in the Webservices and APIs. It is handy for web applications that use Service Oriented Architecture (SOA). It has minimal load testing functionality.  JMeter focuses on performance testing, primarily load testing. It is great for analyzing the performance of your website or application under heavy load.


Ease Of Use

SoapUI has a user-friendly interface that is simple, easy to use, and intuitive. You can easily import and adjust your WSDL/XML according to the scenario for running your tests.  JMeter has a bit complex user interface based on forms and has many features for APIs and web applications. It is also because of the graphs, tables, and other forms of output features provided.



SoapUI automatically generates various reports, and these can be downloadable with no effort. SoapUI paid version extends the reporting functionality and provides more granular information.  JMeter does not have any inbuilt reporting feature, and you have to make the report yourself by understanding the outputs of your load testing.


Limitations of SoapUI and JMeter

While both tools are open-source and offer many common functionalities, there are some limitations to load testing.  Load testing in SoapUI requires significant programming efforts to create tests with assertion and scenario simulations. SoapUI also consumes a lot of memory when you generate a considerable load and hangs a lot. This makes load testing difficult with SoapUI if you are used to doing things at speed.

JMeter, on the other hand, lacks reporting capabilities, which are crucial to identify performance bottlenecks and optimize for them. Without in-built reporting, you would waste lots of time making reports and figuring out problems rather than solving the performance issues. JMeter user interface is also not very good, making it hard to work with.


LoadView: Best Load Testing Alternative to SoapUI and JMeter

LoadView is a cloud-based load testing tool that eliminates the limitations of SoapUI and JMeter. Let’s see how LoadView does it and what are the other features that make it stand out from other load testing tools.

User Interface. LoadView has a simple, intuitive, and utility-based user interface with no learning curve. You can quickly get started within minutes with your load testing.

Reporting. LoadView generates detailed performance testing reports with useful insights so that you can immediately start optimizing your website/application for performance issues.

No Programming Required. LoadView comes with a point-and-click feature called EveryStep Web Recorder, which you can use to capture complex user actions such as mouse clicks, keypresses, menu navigation, etc., and generate test scripts.

No Upfront Investment. Unlike SoapUI and JMeter, where you need to set up your own testing infrastructure and maintain it, LoadView is a cloud-based and fully managed load testing tool, and you pay according to your testing requirements.

Real Browsers and Devices. LoadView supports 40+ browsers/devices to simulate real-world users for accurate load testing.

Geo-locations. With LoadView, you can generate load from over 20 geo-locations for creating the most realistic test scenarios as your users will come from different locations and experience different performance.

LoadView is perfect for load testing your APIs, web applications, web pages, Streaming services as it is capable of generating load according to your requirements without any limitations and programming skills.


Conclusion: The Difference Between SoapUI and JMeter

SoapUI and JMeter are both open-source APIs and webservices testing tools that are good for load testing. However, both tools have their limitations. SoapUI is troublesome for generating a huge load, and JMeter doesn’t offer off-the-shelf reporting. LoadView is a cloud-based toad testing tool that overcomes all the limitations of SoapUI and JMeter with many other great features to optimize your websites.  Read more about the advantages of LoadView over SoapUI.
