The Lions Operating System

This is the source code for LionsOS, an operating system based on the seL4 microkernel using the seL4 Microkit.

LionsOS is aimed at embedded, IoT and cyberphysical systems and is designed to be formally verifiable, adaptable to a wide class of use cases in the target domain, while at the same time setting the benchmark for performance of microkernel-based operating systems. We aim to achieve all three goals by a highly modular yet ruthlessly performance-oriented design and strict adherence to the time-honoured KISS principle.

LionsOS and its verification story are under active research and development.

For more information, see the website.
