Habitat is an open-source project housed under the Chef company but it is a whole new toolkit entirely independent from past Chef software.
With Habitat, you can automate your project’s development, build, and deployment workflows in a way that follows the app and is entirely independent of what platform your developers use or servers run. Habitat provides an entirely new package ecosystem that lets application atomically declare exactly what it needs instead of inheriting from an operating system or container image. A Habitat-built application artifact is guaranteed to run exactly the same way on every platform at any time and can be deployed to container, virtual machine, or bare metal.
