Rooted in the kernel.
Unbound by convention.

An independent open-source circle exploring Android internals, Linux kernels, and native systems.

About

好奇心の赴くままに。

We build close to the system.

Drawn to what happens beneath the surface, we explore how systems work, make tools of our own, and share what we discover in the open.

Fields of exploration

  • Android internals
  • Linux kernel engineering
  • Native systems programming
  • Open-source experimentation
