Managarm is a pragmatic microkernel-based operating system written in modern C++ with a fully asynchronous I/O API. It provides POSIX and Linux user-space API compatibility (epoll, signalfd, tmpfs, /proc, /sys) while running its own non-Linux kernel.
Use cases
- try a microkernel OS with POSIX compatibility
- study asynchronous I/O kernel design
- run a non-Linux 64-bit OS in QEMU
- experiment with Linux API compatibility on a microkernel
- contribute to an open-source hobby operating system
- test software against a Linux-compatible but non-Linux kernel
When to choose
- you want to explore or contribute to a microkernel OS with modern asynchronous I/O design
- you need a POSIX/Linux-compatible user space on a non-Linux kernel for research or testing
- you want a self-contained OS image to boot in QEMU on x86-64, aarch64, or riscv64
When to avoid
- you need a production-ready daily-driver OS with broad hardware and application support
- you require a mature ecosystem, extensive driver coverage, or vendor support
- you just want a Linux distribution rather than an independent kernel
