Rendering incompatible content within a user interface

An increasing amount of the world's content resides on the web in a form targeted to web browser rendering. It may be advantageous to utilize this web content within non-web-based rich client applications because such rich client applications may provide robust features and/or interactions that web-based platforms lack. Unfortunately, integrating web content into non-web user interfaces may be a difficult task. Accordingly, one or more systems and/or techniques for rendering web content within a user interface are disclosed herein. In particular, a composition component may be configured to invoke one or more rendering components to generate rendered web content in a common format within a surface. The rendered web content may be provided to a user interface for display. An input component may be configured to invoke a rendering component to update rendered web content based upon interaction with rendered web content within the user interface.
