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](https://en.wikipedia.org/wiki/Software_development "Software development") lifecycle toolchain. It is designed, developed and marketed by [Neotys](https://en.wikipedia.org/wiki/Neotys "Neotys"), a [privately owned company](https://en.wikipedia.org/wiki/Privately_owned_company "Privately owned company") based in [Gémenos](https://en.wikipedia.org/wiki/G%C3%A9menos "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. Tests can be performed from inside the firewall (in-house) or from the [cloud](https://en.wikipedia.org/wiki/Cloud_computing "Cloud computing"). In addition to simulating [network traffic](https://en.wikipedia.org/wiki/Network_traffic "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](https://en.wikipedia.org/wiki/Bottleneck_\(software\) "Bottleneck (software)") for tuning the application and the supporting servers. It monitors the newest web, [database](https://en.wikipedia.org/wiki/Database "Database") and application servers such as [JBoss](https://en.wikipedia.org/wiki/JBoss "JBoss") application server, [HP-UX](https://en.wikipedia.org/wiki/HP-UX "HP-UX") 11, [Weblogic](https://en.wikipedia.org/wiki/Weblogic "Weblogic"), [WebSphere](https://en.wikipedia.org/wiki/WebSphere "WebSphere"), [Apache Tomcat](https://en.wikipedia.org/wiki/Apache_Tomcat "Apache Tomcat"), and [MySQL](https://en.wikipedia.org/wiki/MySQL "MySQL") database. Its "scripts" are developed via a [GUI](https://en.wikipedia.org/wiki/Graphical_user_interface "Graphical user interface"), which provides conditions, loops, and other programming structures. [JavaScript](https://en.wikipedia.org/wiki/JavaScript "JavaScript") may be inserted for more advanced uses, such as password encryption. - It supports [basic](https://en.wikipedia.org/wiki/Basic_access_authentication "Basic access authentication"), [digest](https://en.wikipedia.org/wiki/Digest_access_authentication "Digest access authentication"), [NTLM](https://en.wikipedia.org/wiki/NTLM "NTLM") and [form-based](https://en.wikipedia.org/wiki/Form-based_authentication?action=edit&redlink=1 "Form-based authentication (page does not exist)") authentication. - It can record HTTP and [HTTPS](https://en.wikipedia.org/wiki/HTTPS "HTTPS") requests, play them back and supports client certificate authentication. - It supports [ActiveX](https://en.wikipedia.org/wiki/ActiveX "ActiveX") components as long as communication with the server is via the [HTTP](https://en.wikipedia.org/wiki/HTTP "HTTP") protocol. - It supports any type of web application including those using [J2EE](https://en.wikipedia.org/wiki/J2EE "J2EE"), [.NET](https://en.wikipedia.org/wiki/.NET_Framework ".NET Framework"), [AJAX](https://en.wikipedia.org/wiki/AJAX "AJAX"), [Flex](https://en.wikipedia.org/wiki/Adobe_Flex "Adobe Flex"), [Silverlight](https://en.wikipedia.org/wiki/Silverlight "Silverlight"), [GWT](https://en.wikipedia.org/wiki/Google_Web_Toolkit "Google Web Toolkit"), SOAP, [PHP](https://en.wikipedia.org/wiki/PHP "PHP"), [Push technology](https://en.wikipedia.org/wiki/Push_technology "Push technology"), etc. as long as they are HTTP 1.0 or 1.1 compliant. - It supports hybrid and native mobile applications. - It supports video (HTTP streaming and RTMP). - [JSON](https://en.wikipedia.org/wiki/JSON "JSON") and [SPDY](https://en.wikipedia.org/wiki/SPDY "SPDY") protocol are also supported. - It [emulates Network](https://en.wikipedia.org/wiki/Network_emulation "Network emulation") conditions (latency, packet loss and bandwidth).
