SkyOS is an Unix-like operating system with monolithic kernel.The OS supports multiple users and symmetric multiprocessing.

Graphics and GUI

SkyOS has an integrated graphics subsystem with support for desktop compositing including double buffering and transparency. SkyOS GUI also allows system-wide mouse gestures.


SkyFS is a fork of the OpenBFS filesystem.SkyOS can also be run from the following filesystems:

Fast searching

SkyOS offers real-time file content query searches with multiple keywords (comparable to Beagle in Linux or Spotlight in macOS), including indexing of files and programs.

Porting applications

Most command-line applications that were written to be compiled with the GNU Toolchain can be ported to SkyOS with little or no modification.SkyOS contains several frameworks for creating applications (including Mono port). Ported applications include Mozilla Firefox, Mozilla Thunderbird, Nvu,WEB, Miller, Tim,weblink Four alternative operating systems, SkyOS, NewsForge, June 14, 2006,weblink" title="">weblink November 8, 2006, April 13, 2019, GIMP and AbiWord. There was also a monetary incentive for porting applications as the SkyOS community voted for desired programs and then supported developers with donations.


Although SkyOS offered many interesting features, limited application and hardware support was its main weakness (eg. only a few graphics cards allowed 2D acceleration).Kernel and drivers updates were solely worked on by Szeleney, and because of this he was unable to keep up with new devices. This was one of the reasons the development ended for this project. In the end, the OS was not able to expand beyond a small albeit dedicated user community. Apart from a short early open source time period, the OS had a proprietary licence with a commercial model based on paid beta-testing. This led to some controversy as SkyOS developers were accused of unauthorized use of open source software. No proof of any wrongdoing was given, but the public image of the OS was tarnished nevertheless.
