What is SoapUI?

SoapUI is the world's most widely-used open source API testing tool for SOAP and REST APIs. SoapUI offers SOAP Web Services functional testing, REST API functional testing, WSDL coverage, message assertion testing and test refactoring. With over 10 years of experience backed by a vast open source community, SoapUI is the de facto method for ensuring quality when developing APIs and Web Services.

Why was SoapUI developed with an open source approach?

When SoapUI was initially created in 2006, there was no open source API testing tool on the market. The initial idea behind SoapUI was “Let’s get a lot of people to help!” – since then, developers have contributed code and provided valuable feedback, making SoapUI the product that it is today. Because SoapUI is open source, usage and adoption spread quickly once it was launched. SoapUI is the most powerful open source SOAP and REST API testing tool and has benefitted from the vast numbers of testers and developers trying the product and spreading awareness of its functionality. Without the open source community, SoapUI would not have the millions of users that it does today, making it the most widely used open source API tool for over 10 years.
