You are here: Open Source Flash » SILEX




SILEX is an open source Rich Internet Application that provides designers with tools and a workflow in order to produce rich media applications more efficiently than ever. It separates content and design as well as programming and designing.

You may download and install a SILEX server in minutes. Produce your layouts and create URLs that will lead to applications based on these layouts. Then use the WYSIWYG online interface to place medias and components.

Our software is “free software,” part of the new paradigm of sharing across the Internet, and licensed under the GPL. If our code is used by other people in their software, their code also becomes open. A viral effect! :)

SILEX is a 3 years old project already used by designers and web agencies to produce RIAs and Flash websites.

It became an open source project in April 2007 in order to facilitate the cooperation of several companies interested in the project. These partners provide us for two developers available one day a week and for a place to work together with designers one day a week in Paris. I hope it will also be used by associations to produce low cost and easily maintainable web TVs.
