SmartBear ReadyAPI is a commercial API testing suite with functional testing, performance and virtualization modules. Pages here cover SoapUI Open Source, Bruno, Microcks, WireMock, k6 and JMeter.
What teams give up and keep when they drop ReadyAPI for SoapUI Open Source, its EUPL-licensed sibling: basic functional and performance testing stay, while data-driven testing, coverage, Groovy debugging, security testing and virtualization belong to the paid suite.
For teams testing both REST and SOAP services in ReadyAPI: Bruno's WSDL and OpenAPI import, Git-stored collections and bru CLI runs in CI against ReadyAPI's functional testing module, and which SOAP-heavy test suites are still better kept in a SoapUI-based tool.
Replacing ReadyAPI's service virtualization module with self-hosted mocks: Microcks, which imports SoapUI projects and OpenAPI, AsyncAPI and gRPC definitions, or WireMock for HTTP stubbing, and how virtual services move into CI and shared test environments.
Moving API load tests from ReadyAPI's performance module to Grafana k6 (AGPL-3.0, JavaScript scripts) or Apache JMeter (Java, wide protocol coverage including SOAP and JDBC): rewriting scenarios, running load generators yourself and reading results.
ReadyAPI is sold as customizable plans through SmartBear without public prices. This page breaks down the cost components to compare: per-module licenses against the setup, maintenance and support time for SoapUI Open Source, Bruno, Microcks and k6.
