  Description     : API and web service testing tool

SoapUI is a free and open source cross-platform functional testing solution for
APIs and web services.  SoapUI allows you to easily and rapidly create and
execute automated functional, regression, and load tests. In a single test
environment, it provides complete test coverage - from SOAP and REST-based
Web services, to JMS enterprise messaging layers, databases, Rich Internet
Applications, and much more.

As a Java developer I can tell that many of us used SoapUI a lot in
times when WebServices and WSDL was a de-facto standard for APIs.
Today Postman is mostly used for REST APIs but the SoapUI is still
powerful and even recently received a GraphQL support.
It's one of the main tools for QA automation. Similar to JMeter that
was already debianized.

I tried it now and the design remains the same :) But I hope they'll improve it.
It has quite annoying popups with ads to upgrade to a paid Pro plan
and ReadyAPI tool.

I think it worth adding. But not a top priority.
