Cloud Foundry vs Flynn: What are the differences?

Developers describe Cloud Foundry as "Deploy and scale applications in seconds on your choice of private or public cloud". Cloud Foundry is an open platform as a service (PaaS) that provides a choice of clouds, developer frameworks, and application services. Cloud Foundry makes it faster and easier to build, test, deploy, and scale applications. On the other hand, Flynn is detailed as "Next generation open source platform as a service". Flynn lets you deploy apps with git push and containers. Developers can deploy any app to any cluster in seconds.

Cloud Foundry and Flynn belong to "Platform as a Service" category of the tech stack.

Some of the features offered by Cloud Foundry are:

• Application and services centric lifecycle API
• High performance dynamic routing
• Buildpack support

On the other hand, Flynn provides the following key features:

• Flynn goes beyond 12 factor apps. Run any Linux process written in any language or framework, even stateful apps on your own servers or any public cloud.
• Scaling or adding a new cluster is simple: just add more nodes. Everything is containerized, Flynn takes care of distributing work across the cluster.
• Flynn is 100% free and open source. Flynn works great out of the box, and since Flynn is modular and API-driven it's easy to modify and swap components to suit your needs.

Cloud Foundry and Flynn are both open source tools. It seems that Flynn with 7.24K GitHub stars and 534 forks on GitHub has more adoption than Cloud Foundry with 605 GitHub stars and 532 GitHub forks.
