eyeos is an open source web desktop following the cloud computing concept. It is mainly written in PHP, XML, and Javascript. It acts as a platform for web applications written using the eyeos Toolkit. It includes a Desktop environment with 67 applications and system utilities. It is accessible by portable devices via its mobile front edu. eyeos lets you upload your files and work with them no matter where you are. It contains applications like Word Processor, Address Book, PDF reader, and many more developed by the community.

For developers, eyeos provides the eyeos Toolkit, a set of libraries and functions to develop applications for eyeos. Using the integrated Portage-based eyeSoft system, anyone can create their own repository for eyeos and distribute applications through it.

Each core part of the desktop is its own application, using javascript to send server commands as the user interacts. As actions are performed using ajax (such as launching an application), it sends event information to the server. The server then sends back tasks for the client to do in XML format, such as drawing a widget.

On the server, eyeos uses XML files to store information. This makes it simple for a user to set up eyeos on a server, as it requires zero configuration other than the account information for the first user, making it simple to deploy. To avoid bottlenecks, that flat files present, each user’s information and settings are stored in different files, preventing resource starvation from occurring.
