Type of web server benchmarking utility

OpenSTA Developer CYRANO Stable release 1.4.4 / October 19, 2007 (2007-10-19) Written in C++ Operating system Microsoft Windows Type Load Testing License GNU General Public License 2.0 Website opensta.org

**OpenSTA** is a [feature-rich](/source/Feature-rich) GUI-based [web server benchmarking](/source/Web_server_benchmarking) utility that can perform scripted HTTP and HTTPS heavy load tests with performance measurements.[*[citation needed](https://en.wikipedia.org/wiki/Wikipedia:Citation_needed)*] It is freely available and distributable under the [open source](/source/Open-source_license) [GNU General Public License](/source/GNU_General_Public_License). OpenSTA currently only runs on [Microsoft Windows](/source/Microsoft_Windows)-based operating systems.

Scripts are recorded in a [proprietary language](/source/Proprietary_programming_language) called "SCL". It is a fairly simple coding language that provides support for custom functions, variable scopes, and random or sequential lists.

OpenSTA was originally written by Cyrano. Cyrano's intentions were to write commercial plug in modules and support for OpenSTA for performance testing non-web applications.

Note that the most recent version posted on the [OpenSTA home page](http://opensta.org/) is 1.4.4, released 27 Oct, 2007.
