LoadUI is a Open Source Load Testing solution that is free and cross-platform. With a visual, drag-and-drop interface, it allows you to create, configure and redistribute your Load Tests interactively and in real-time. In a single test environment, LoadUI provides complete test coverage and supports all the standard protocols and technologies. And it’s so powerful, it generates scalable, high-volume and real-world load from any number of local and remote computers. Meet LoadUI, the future of Load Testing.

Server Monitoring

With extended server monitoring LoadUI Pro will not only deliver response times and through-put but also detailed information on anything from CPU and RAM usage to database performance and resource utilization. Basically LoadUI will answer the question "Are you all right?", while LoadUI Pro will tell you what’s wrong. LoadUI Pro is offered in two different versions, nodelocked or floating license. Either way you have unlimited load generation and virtual users with a twist of a nob

Powerful Distribution

Running load tests usually involves simulating large amounts of traffic at specific times. Due to the amount of computer resources this takes, it can become difficult to do this using a single computer. In LoadUI Pro, each virtual user scenario can be distributed out to a number of LoadUI agents, where they will be executed just like in the desktop application. Having these LoadUI Pro agents physically located in a remote location can more accurately simulate traffic coming from outside the network.

Interactive Testing. In Real-Time.

Before LoadUI, Load Testing was very static and counter intuitive. You had to first create the tests and then run them to the end before you could update them. With its Real-time Testing technology, LoadUI changes all that. Now you can create, configure, and update your tests in real-time – while the tests are running. This allows you to more intuitively load test your service, and experiment to find results you would otherwise have missed. Also, the time of having to wait for your current test run is over, before editing certain parameters are over.
