SoapUI

SoapUI is available in two main versions: the open-source SoapUI and the commercial ReadyAPI. The open-source version is completely free to download and use, making it an excellent choice for individuals, small teams, or organizations with basic API testing needs. It includes core features like functional testing, support for SOAP and REST protocols, and scripting capabilities using Groovy and JavaScript. For users who require more advanced features—such as security testing, load testing, data-driven testing, and detailed reporting—SmartBear offers ReadyAPI, a premium suite built on top of SoapUI. ReadyAPI is a paid product with tiered pricing plans based on the number of users and the specific modules needed. Pricing details for ReadyAPI are available on SmartBear’s website and typically vary depending on whether you choose annual or perpetual licenses, with options for enterprise-level support and integrations.
