Chimera uses a novel combination of core tools from FreeBSD, the LLVM toolchain, and the Musl C library, delivering a fresh experience with several major benefits.

Chimera aims to eliminate legacy cruft where possible to deliver a modern, general purpose, fully featured operating system that is simple but complete.

Buildable from source.

Chimera is a binary distribution, but a source package build system is provided, enabling easy packaging of new software, builds of custom packages, and accessible infrastructure.


You can use Chimera on all kinds of processors, including Intel/AMD, ARM AArch64, POWER and RISC-V. Central build system ensures packages are available everywhere.
