history

Project history and usage

KraftKit is the `kraft` command-line tool and Go framework for building, packaging, running, and deploying Unikraft unikernel virtual machines. It packages the unikernel workflow into a developer-facing CLI modeled after familiar package managers and build tools.

Project history

The unikraft/kraftkit repository was created on March 16, 2022, as the Go-based successor and companion tooling around the Unikraft unikernel project. The repository describes KraftKit as a suite of tools for custom, minimal, immutable lightweight unikernel virtual machines based on Unikraft.

Unikraft itself came from the systems-research and unikernel world, where the goal is to compile an application with only the OS components it needs. KraftKit made that workflow look more like a modern developer CLI: install a `kraft` binary, build a project, run it locally with backends such as QEMU, package artifacts, and deploy to Unikraft Cloud.

Adoption history

KraftKit adoption tracks the effort to make unikernels approachable beyond research labs. The official docs call `kraft` Unikraft's companion command-line tool and say it was modeled after popular package managers and build tools to make building and managing applications as unikernels easier.

Homebrew packaging matters for KraftKit because local macOS installation is one of the low-friction paths into a workflow that otherwise spans compilers, virtualization, OCI-style packaging, manifests, cloud deployment, and runtime management.

How it is used

The package installs the `kraft` executable. The CLI can build, clean, configure, package, pull, push, run, start, stop, inspect, and deploy Unikraft unikernels; the official CLI reference also documents local runtime, networking, volume, compose, cloud, image, service, autoscale, certificate, and completion commands.

Why package nerds care

KraftKit is interesting to package nerds because it treats unikernel components like packageable artifacts. It combines a language/toolchain installer, build orchestrator, package manager, local VM runner, and cloud deployer into one CLI, which is exactly the kind of tool that benefits from clean Homebrew distribution.
