BareMetal is an exokernel-based single address space operating system (OS) created by Return Infinity.
It is written in assembly to achieve high-performance computing with minimal footprint[3][4] with a "just enough operating system" (JeOS) approach.[5] The operating system is primarily targeted towards virtualized environments for cloud computing, or HPCs due to its design as a lightweight kernel (LWK). It could be used as a unikernel.
It was inspired by another OS written in assembly, MikeOS,[2] and it is a recent example of an operating system that is not written in C or C++, nor based on Unix-like kernels.[6]
