# About Parallels User Portal

Parallels User Portal is a client application that runs in a web browser.  You can use Parallels User Portal to view and launch remote applications and desktops from a web browser.

Compared to platform-specific Parallels Clients (Parallels Client for Windows, Parallels Client for iOS, etc.), Parallels User Portal 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 User Portal. Nonetheless, Parallels User Portal is a fully-featured platform-independent client providing end users with an alternative method of working with remote resources published via Parallels RAS.

## **System requirements**

* Any HTML5-enabled web browser, except Internet Explorer.
