Loadzen is a cloud-based load and performance testing tool built for humans. The system leverages the power of the cloud to allow you to emulate thousands of virtual users coming to your site or webapp. The app will not only test the site, but allows you to create multiple user journeys and mix them into your test and will give you real-time results as it runs. If you want more control over the test, download our chrome plugin and record your test from the comfort of your browser, then using our intuitive test wizard - set up your test and go!


LogFaces is created to be an out-of-the-box log server which can be easily hooked with existing applications using log4j as their logging framework. "Off the shelf" is the major feature - you simply install it next to your system and redirect your appenders to logFaces server; it works with TCP or UDP sockets - both well supported by log4xxx. It's up to you which processes, hosts or even classes should be working with logFaces- thanks to log4xxx configuration magic, all this is very simple and not intrusive.

Webserver Stress Tool

Webserver Stress Tool simulates large numbers of users accessing a website via HTTP/HTTPS. The software can simulate up to 10,000 users that independently click their way through a set of URLs. Based on the parameters you specify, the application not only requests the HTML of a URL, but also frames, images, flash files etc., emulating the same behaviour a web browser would show when accessing the website.

Web Performance

The Web Performance Load Tester is a performance testing tool for websites with an automated record and config process that cuts load testing time by up to 80%.
