musl libc - Projects using musl Linux distributions using musl Abyss - An independent Linux distribution based on musl and pure LLVM. Adélie Linux - A small, independent Linux distribution focused on delivering a high quality operating environment, aiming for POSIX® compliance, compatibility with a wide variety of computers, and ease of use without sacrificing features. Alpine Linux - based on musl since the 3.0 release. Ataraxia Linux - Independent, multi-platform, general purpose operating system based on the Linux kernel and musl libc. Supports 17 different CPU architectures Has merged /usr for better compatibility Extremely bleeding edge Uses ZSTD where it’s possible. Kernel, modules and initrd are using ZSTD by default. Bedrock Linux - as of version 1.0alpha4 bootstrap-linux - consists only of a minimal set of packages that can be crosscompiled. kernel, toolchain, busybox. Chimera Linux - use musl, LLVM toolchain and FreeBSD userland with Linux kernel Cross Linux From Scratch - CLFS uses musl since 16.10.2013 (Announcement) Dragora - An independent GNU/Linux-Libre distribution based on concepts of simplicity. Contains 100% free software. Musl is included in Dragora for the 3.0 series (back in 2012). Per-package directories using qi (an own package manager) and graft following the GNU stow’s spirit. /usr merge, offering compatibility with the Filesystem Hierarchy Standard (FHS). Uses sysvinit combined with perp for the supervision of critical services. Supports several architectures via bootstrap, but is currently available for x86 (i586+), x86_64. Embedded Linux From Scratch - a fork of CLFS embedded using musl libc 2013-09-28 Updated to correct name of toolchain used 2013-09-14 Updated to musl-0.9.13. Supports *-*-musl* toolchains. Exherbo has an x86_64 musl stage. Gentoo has stages for most architectures (has musl overlay for packages without mainline support yet) https://distfiles.gentoo.org/releases/amd64/autobuilds/current-stage3-amd64-musl/ https://distfiles.gentoo.org/releases/x86/autobuilds/current-stage3-i686-musl/ https://distfiles.gentoo.org/releases/arm/autobuilds/ glaucus - A simple and lightweight Linux® distribution based on musl libc and toybox Iglunix - An independent, self-hosting, Linux distribution with no GNU software KISS Linux - An independent Linux distribution with a focus on simplicity and the concept of “less is more”. Mere Linux Built on the mere package manager, written in Zig, with a content-addressed immutable store and atomic upgrades Uses s6 for process supervision and LLVM/Clang as the primary toolchain morpheus - suckless linux distro oasis - statically linked linux distribution based on musl and other lightweight components. OpenWrt - defaults to musl as libc since 2015 (OpenWrt-commit) except for (as of April 2025) arc CPU ISA (OpenWrt-reference) sabotage - experimental Linux distribution based on busybox and musl. About 700 packages including X11, LXDE, alsa, SDL, C++. Supports i386, x86_64, arm, mips, powerpc Uses lightweight replacements for netlink, pkg-config, and gettext Optimized for build speed and small binary size Per-package directories following stow/gobolinux spirit Snowflake Includes only of a minimal set of packages that can be crosscompiled. (Kernel, toolchain, busybox, gawk, make and sed) Uses pkgsrc for additional packages, so supports thousands of packages Mainly a platform for testing usrview, a system for per-process views of /usr, for very fine-grained control of package management. solyste - statically linked linux distribution targetting embedded hardware and various architectures Talos - A modern Linux distribution for Kubernetes. TAZ - a Gentoo-based livecd/livedvd Vanilla - A radically different, new, simple, customizable Linux distribution based on musl, busybox using LLVM/Clang as toolchain. Void Linux provides official musl based images. Linux distros shipping musl as an optional package Arch Linux Chromebrew provides an official musl package. Debian package is available. Fedora package is available starting with Fedora 30. Guix package is available. Ubuntu package is included in the universe section of the repository starting with Ubuntu 14.04 Trusty Tahr. There is also a PPA available (ppa:bortis/musl) for Saucy Salamander. openadk Embedded Linux buildsystem, musl can be selected as the libc of the system. Yocto - OpenEmbeeded based Yocto Project supports generated embedded Linux distributions based on musl C library Set TCLIBC = “musl” to switch default C library to musl for building embedded linux platforms poky-tiny ( Yocto Project Reference Distribution ) is now based on musl Yoe Distro - Fully supports Generating musl based images Other Projects Third-party projects using or building on musl: buildroot toolchain has musl libc option docker-muslbase minimal musl-based docker container Dwarf Fortress port ELLCC is a Clang/LLVM and musl based cross compilation toolchain for embedded systems Emscripten is a LLVM-based compiler from C to C++ to JavaScript, using most of musl (some filesystem parts are written in JavaScript) Firecracker VMM is an open source virtualization technology that is purpose-built for creating and managing secure, multi-tenant container and function-based services. Mirage OS is an Xen guest written in OCaml, its floating-point formatting code is from musl. Mission Pinball Framework is an open source framework to program real pinball machines. It uses musl to cross-compile binaries for embedded targets such as Stern Spike. mussel The shortest and fastest script to build working cross compilers targeting musl libc NodeOS linux with Node.js as userspace OSv “cloud” operating system used a musl based libc Rust is a programming language with musl supported as a cross-compilation option seL4 seL4 kernel ships with musl simplecct simple cross compiler toolchain toybox simple Unix command-line utilities
