PHP Application Framework
A flexible API and event model that allows you to override core behavior. You get incredible flexibility along with the ability to customize MODx to your needs and maintain a simple upgrade path. If you're curious, you can learn more about our PHP Application Framework functionality.
Strong Web Standards Support
MODx does not force you into awkward and confusing blocks-this or channels-that templating engines or layout rules. You can build XHTML 1.0 Strict sites just as easily as a tag-soup-table layout. MODx is the dream CMS for CSS and Standards oriented designers.
Graphical Installer
Less experienced and new users can get up and running fast with a step-by-step, web-based installer.
Improved Rich Text Editors
MODx Rich Text Editors for content are optional plug-ins, making for a smaller base-download. TinyMCE currently ships ready to use. Adding new or preferred RTEs to MODx is simple with FCKeditor available now (as an optional download) and Textile, Markdown and widgEditors on their way.
Robust CSS Menu Builder
Menus made from ULs (unorderd lists) are ready to go out of the box. Whether you want something simple as a bulleted list for a sidebar or as complex as Big John's deluxe menus complete with CSS "hover zones", MODx has you covered.
Works in your favorite browser
You don't need to install extra software to manage your site. In fact, all you need is a modern web browser to edit your content. You can manage your websites from anywhere in the world with an internet connection and stable production releases of IE 7, Safari 3 or Firefox 3, or higher.
Web 2.0 Features (yes, that means Ajax)
MODx is the first free PHP CMS to offer an API that fully supports Web 2.0 Ajax technology. MODx doesn't force you into choosing a single Javascript library. Our Ajax CMS gives you the freedom to choose jQuery, Mootools, ExtJS, Prototype or any other library you choose, even ones that aren't out yet. You can even make use of Ajax today in your own custom sites including live search, web effects, Ajax communications and more.
