A user friendly, POSIX compatible operating system

Reducing software waste

Welcome on the new web site for the Syllable operating system project. Syllable is a unique and complete operating system that is easy to use, powerful, lightweight and extraordinarily fast and responsive. It has its own, tightly integrated kernel, file system, Graphical User Interface and applications, and also supports many cross-platform open-source programs. Syllable Server is a matching, small and efficient, companion Linux system. Syllable makes better use of your hardware by reducing waste in the software. It can make a new or tiny computer extremely fast and an old computer usable again.

Stay tuned!

Road Map

Current priorities, in order. Syllable has been in hibernation for some time, but we are waking the sleeping beauty. There is no time schedule for these developments. Much depends on support from the community and funding by organisations. We can implement specific wishes when there is funding for them. In times when there is no funding, we will follow our own priorities, which usually follow the low-hanging fruit.

In Progress
Medium Term
Long Term
