SkylightOS

SkylightOS

The current total lines of code counter is intermittently broken, upstream from shields.io

Current Codename: Esaul

SkylightOS is a small, portable and extensible RTOS designed for a multitude of platforms. Skylight is designed from the ground up, free from any arbitrary limitations of traditional platforms. Skylight can easily be ported to a device or general platform of your liking easily and is highly extensible for developers and users alike.

SkylightOS is not POSIX compliant by design, this may be followed up in the future with a POSIX compliant subsystem but this is just a pipedream for now.

For a roadmap on Skylight's development, check the SkylightOS Milestone Roadmap
