MirageOS is a library operating system that constructs unikernels for secure, high-performance network applications across a variety of cloud computing and mobile platforms.
MirageOS applications are written in OCaml and compiled into a complete image that can be run on Xen. The libraries include a network stack, http, and a complete SSL library, and Irmin, a distributed git-like data store.
MirageOS is an official Xen Project incubator project.
Code is released under the ISC license, with some code released under LGPLv2.
