Site Press is a free hosted content management system (CMS) written in C#, with an architecture that supports easy creation of themes with Web-standard markup and easy extensibility through the creation of plugins and modules.

If you're a Web developer, you'll find creation of Site Press themes to be very straightforward. Just checkout our Site Press Development Guide, or download one of our themes and look at the underlying markup.

Site Press functionality can be extended through ASP.NET code modules called plugins. Guidelines for writing plugins will be posted soon. Contact us if you're interested in creating Site Press plugins - we'll be glad to work with you to create your plugin!
