description LoadUI Overview

LoadUI is an open-source load testing tool originally developed by SmartBear, designed to test the performance, scalability, and reliability of web APIs and services. It integrates closely with SoapUI, allowing developers to reuse existing functional tests for load testing scenarios. Users can simulate high volumes of concurrent traffic across multiple protocols, including HTTP, REST, SOAP, and JDBC. It is intended for quality assurance professionals and software developers who need to identify bottlenecks and verify system behavior under stressful conditions before deployment.
