Welcome to Unikraft's Documentation 👋

Unikraft is a faster and more secure alternative to running your application in a container or Linux VM. Instantly boost your application with minimal effort.


Unikraft is a fast, secure and open-source Unikernel Development Kit which enables you to easily build minimal, ultra-lightweight virtual machines (known as unikernels). Running your application with Unikraft provides:

  • High performance and ultra lightweight deployments.
  • Strong, hardware-level isolation (they're VMs!) and a minimal TCB.
  • Ease of use, including integration with Dockerfiles and other mainstream tools.
  • Compatibility with the Linux API.

The Unikraft ecosystem consists of an extensive build system and tooling, libraries and pre-built unikernel applications. All of the source code is open-source and licensed under BSD-3-Clause (contributions welcome!). As an active community, we host regular working groups, hackathons, meetups and more.

Quick Start#

To begin first install the kraft tool, which allows you to easily leverage Unikraft unikernels at every stage of their lifecycle, from construction to production:
