Dusken OS
Development progress

An operating system, written from scratch.

Kernel, drivers, desktop, network stack and web browser, built line by line with no Linux underneath. Every number on this page comes straight from the source tree.

System map

        
Every milestone, in orbit

        
Each ring is a part of the system and each light a milestone reached. Hollow, pulsing lights are what comes next. Pick a ring to follow it.

      

    

    

      

      

    

  






  

    

      

        
Where it runs

        
Processors and machines

        
Three processor types, tested automatically in emulation on every release, and confirmed by hand on real virtual machine hosts. A physical PC is still to come.

      

    

    

    

  






  

    

      

        
Screens

        
Straight from the test runs

        
Real screenshots saved during Dusken's automated test runs. No mock-ups.
