Reasons to Consider an Alternative to SoapUI
SoapUI is an open-source tool for performing tests for SOAP and REST APIs. The reason why it gained popularity is that it allows users to perform functional tests, load tests, and security tests for API with ease.
However, many users are tempted to look for alternatives as the tool comes with drawbacks. They are as follows:
- Complexity: Since SoapUI is packed with numerous features, the tool may appear cumbersome to beginners. It might take some time for them to learn about those features. Alongside that, the test results aren’t well-structured, so they can be difficult to read.
- Not cloud-based: Unlike most API testing tools, SoapUI isn’t cloud-based, so teams don’t have the opportunity to collaborate in the cloud. Since the tool is stored locally, it requires regular maintenance, which can be a hassle.
- Lack of integrations: Being an open-source tool, SoapUI currently doesn’t have any native SDLC integrations, However, its pro version called, ReadyAPI offers integration with Jenkins, TeamCity, and Azure DevOps.
- Greater memory consumption: According to many users, SoapUI tends to consume plenty of memory. It happens even if the application isn’t being used, but running in the background.

On the other hand, SoapUI is only capable of testing and mocking API. Its user interface isn’t as well-structured as Postman’s, so beginners are likely to spend some time getting familiar with it.
Considering what both platforms have to offer, Postman is the clear winner.
Pros:
- Intuitive interface makes it easy for beginners
- Various integrations available
- API collections can be saved and shared
- Allows codeless API testing
- It has a huge community for support
