Container Factory vs Powerstrip: What are the differences?

Developers describe Container Factory as "Turn your Github repo into a published container image". container-factory produces Docker images from tarballs of application source code. It accepts archives with Dockerfiles, but if your application's language is supported, it can automatically add a suitable Dockerfile. On the other hand, Powerstrip is detailed as "A tool for prototyping Docker extensions". Powerstrip is implemented as a configurable, pluggable HTTP proxy for the Docker API which lets you plug multiple Docker extension prototypes into the same Docker daemon. For example, you can have a storage adapter (e.g. Flocker) running alongside a networking adapter (e.g. Weave), all playing nice with your choice of orchestration framework.

Container Factory and Powerstrip can be categorized as "Container" tools.

Container Factory and Powerstrip are both open source tools. It seems that Powerstrip with 309 GitHub stars and 31 forks on GitHub has more adoption than Container Factory with 56 GitHub stars and 2 GitHub forks.
