The code is mostly in the https://github.com/GreenteaOS/Tofita and https://github.com/GreenteaOS/Caramel

People check the https://github.com/GreenteaOS/Greentea which currently mostly contains binary assets. This repo will have user-space apps. Currently sample apps are taken from ReactOS project.

Greentea OS is built from scratch in a custom programming language Hexa with custom kernel design (called Tofita Engine)

Demo: https://www.youtube.com/watch?v=vh-icbJuQgg

This is amazing. Is the author of the OS also the author of the language? The language looks pretty high-level; why was it chosen for the OS implementation? What architecture does the kernel have (monolythic, micro, etc.)?

fixn0ll · 14h ago

An operating system with great potential. I really hope that the development will not drag on for decades.
