What's New Just released v0.7 (Mimas)

Unikraft is a fast, secure and open-source Unikernel Development Kit

By tailoring the operating system, libraries and configuration to the
particular needs of your application, it vastly reduces virtual
machine and container image sizes to a few KBs, provides blazing
performance, and drastically cuts down your software stack's attack
surface.

Blazing Fast

Unikraft is faster than Linux

On Unikraft, NGINX is 166% faster than on Linux and 182% faster than
on Docker

Unikraft outperforms well-configured custom Linux kernel images, even
those with security mitigations turned off! Compared to other
Unikernel Development Kits, library OSes and containers, Unikraft
still comes out on top.

We benchmarked NGINX throughput in terms of requests per second
compared to other unikernels, Linux and Docker; Unikraft achieves
182% performance improvement with respect to Docker.

Unikraft has been extensively and carefully benchmarked, read more
