Deis vs Paz: What are the differences?

Deis: Open Source PaaS that builds upon Docker and CoreOS to provide a lightweight PaaS with a Heroku-inspired workflow. Deis can deploy any application or service that can run inside a Docker container. In order to be scaled horizontally, applications must follow Heroku's 12-factor methodology and store state in external backing services; Paz: A Simple Docker PaaS Written in Node.js. A pluggable in-house service platform with a PaaS-like workflow, built on Docker, CoreOS, Etcd and Fleet.

Deis and Paz can be primarily classified as "Platform as a Service" tools.

Some of the features offered by Deis are:

• Deis can deploy any language or framework using a Dockerfile
• If you don't have a Dockerfile, Deis includes Heroku buildpacks for Ruby, Python, Node.js, Java, Clojure, Scala, Play, PHP, Perl, Dart and Go.
• Deis can be deployed on any system that supports CoreOS including your workstation, as well as most public clouds, private clouds and bare metal.

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

• A web front-end to CoreOS' Fleet with a PaaS-like workflow
• Like a clustered/multi-host Dokku
• Beautiful web UI

Deis and Paz are both open source tools. Deis with 6.12K GitHub stars and 863 forks on GitHub appears to be more popular than Paz with 6 GitHub stars and 4 GitHub forks.
