About AlertFox

Meet us at the PartnerPort Office Building in Walldorf/Heidelberg (Germany).AlertFox is an in-depth website transaction monitoring service for Web 2.0 and SaaS web applications. Unlike its predecessors that are stuck in a Web 1.0 mindset, only AlertFox can monitor the function and performance of sites that are based on any of the major rich internet applications (RIA), including AJAX, Flash, Flex, complex HTML and Silverlight technology. AlertFox also helps SaaS users monitor their provider’s reliability. As the first service that can monitor web applications with Flash and Silverlight applets, AlertFox is able to monitor sites like YouTube or Google Docs that previously were not candidates for these types of services. Furthermore, this monitoring runs directly in the web browser, thereby monitoring the true user experience.

AlertFox gives website owners confidence that their sites are performing exactly as intended.

AlertFox is a service of iOpus, the company behind the popular open-source and commercial iMacros browser add-ons for web performance and regression testing. iOpus was founded in 2001 and remains privately held, debt-free and profitable.

AlertFox officially launched on April 24th, 2009. Before our official launch, AlertFox was a semi-finalist in the TechCrunch 50 start-up competition in September 2008 and a finalist in the European Plugg Startup competition in February 2009.

As of December, 2010, the AlertFox monitoring system administers more than 200,000 website tests a day and counting. Our customer roster reflects the diversity of the Internet. From major online stores, e-payment and insurance companies, to SaaS providers and leading Flash game companies, our customers have one thing in common: they all depend on a reliable and well-performing website to stay in business. We are very proud that they have chosen us to watch over their critical web applications.

We would love to help you with your web application monitoring needs, too!
