A modern, general-purpose non-GNU Linux distribution

Chimera is a general-purpose OS based on the Linux kernel. It aims to be clean and usable while addressing the various shortcomings of an average Linux distribution.

It does so by liberating itself from the common baggage of most Linux-based systems and doing its own thing. Software is sourced from different places and sometimes written from scratch.

Alternative userland.

Chimera is not a GNU/Linux - its userland tools are based on FreeBSD, LLVM serves as the system toolchain, and musl provides the C library implementation.

Clean and consistent.

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.

While the system uses apk-tools and therefore binary packaging, it aims to be trivially buildable from source using a build system and package collection created from scratch.


You can use Chimera on all kinds of processors, including Intel/AMD, ARM AArch64, POWER and RISC-V. Architecture tiering system ensures optimal support.

The distribution is in heavy development. Right now, it is a relatively complete graphical system with a multimedia stack and a web browser, capable of running Wayland and X11 environments, such as GNOME and Enlightenment. However, the repositories (source and binary) are subject to arbitrary changes and rebuilds, so it is not yet safe for daily use.

Initial bootable media for a variety of devices are now available. Check the Downloads page for links and instructions. Note that these are pre-alpha quality and are provided solely for testing purposes.

It is currently planned that the distribution will stabilize once apk-tools has released a stable 3.x version. Chimera currently relies on a Git snapshot of apk-tools.

New images

As of today, a new set of images has been released. This is following the complete world rebuild that has been going on the last few days.

The new images are therefore generated from these new packages, and are the last images that are released before the alpha release.

Chimera at FOSDEM 2023 and the path towards alpha

It has been a while without an update post, so perhaps it’s time to refresh things a little.

No news does not mean progress hasn’t been happening; there has been a continuous stream of commits in cports as well as other parts of the project, so I will do my best to summarize it as well as provide an updated overview of what’s going to happen.
