Product summary
SmartBear SoapUI is a mature API testing application aimed at developers and QA engineers who need to automate functional, regression, and load testing. It works with both REST and SOAP services and provides a graphical, scriptable environment for building and running test scenarios, checking responses, and collecting metrics to verify API behavior and stability.
Core capabilities
- Performance and load measurement for spotting bottlenecks and regressions
- Building, running, and organizing test suites and individual test cases
- Native support for SOAP and REST protocols, with message validation and assertions
- Security assessment features and data-driven execution for varied input coverage
- Automation hooks and CI/CD integration to run tests as part of a pipeline
Availability and editions
SoapUI is available as an open-source edition and as a commercial product (ReadyAPI) that adds enterprise features and enhanced support. The tooling runs on major operating systems (Windows, macOS, Linux) and offers both a free option for many use cases and paid licenses for teams that require advanced capabilities.
Other tools to consider
- Postman — widely used, cross-platform, with a robust free tier and collaboration features
- Insomnia — a lightweight, developer-friendly client that supports modern REST workflows
- Paw — a native macOS API client with a polished UI (commercial)
These alternatives can complement or replace SoapUI depending on team preferences, budget, and required workflows.
