# Parallels HTML5 Client Parallels HTML5 Client is a RAS client application that runs in a web browser. Users can use Parallels HTML5 Client to view and launch remote applications and desktop from a web browser. Compared to platform-specific Parallels Clients (Parallels Client for Windows, Parallels Client for iOS, etc.), Parallels HTML5 Client does not require end users to install additional software on their computers or mobile devices. Feature-wise, platform-specific Parallels Clients give users more options than Parallels HTML5 Client. Nonetheless, Parallels HTML5 Client is a fully-featured platform-independent client providing end users with an alternative method of working with remote resources published via Parallels RAS. Please note that the RAS HTML5 Gateway (the server side) requires Windows Server 2008 R2 or higher (it will not work on Windows Server 2008). The only requirement for the client side is an HTML5-enabled web browser.
