ReadyAPI

ReadyAPI is SmartBear’s API testing platform. It combines functional testing of REST, SOAP, GraphQL and other APIs, API performance testing (load, stress and spike tests, formerly LoadUI Pro) and service virtualization.

Tests can be created without code or with scripting and run in CI/CD pipelines with tools such as Jenkins, Azure DevOps and Git. ReadyAPI is a commercial product with a free trial; the former loadui.org domain is now parked.
