It provides testers and developers automatic test design and maintenance, the most realistic simulation of user behavior, fast root cause analysis and built-in integrations with the entire software development lifecycle toolchain.

It is designed, developed and marketed by Neotys, a privately owned company based in Gémenos, France.

NeoLoad works by simulating traffic (up to millions of users) to determine application performance under load, analyze response times and pinpoint the number of the simultaneous users which the Internet, intranet or mobile application can handle.

In addition to simulating network traffic, it also simulates end-user transaction activity including common tasks like submitting forms or executing searches by emulating "virtual" users accessing web application modules.

It provides the performance information required to troubleshoot bottlenecks for tuning the application and the supporting servers.
