Paz vs tsuru: What are the differences?

What is 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.

What is tsuru? Extensible and open source Platform as a Service software. tsuru is an open source polyglot cloud application platform (PaaS). With tsuru, you don’t need to think about servers at all. You can write apps in the programming language of your choice, back it with add-on resources such as SQL and NoSQL databases, memcached, redis, and many others. You manage your app using the tsuru command-line tool and you deploy code using the Git revision control system, all running on the tsuru infrastructure.

Paz and tsuru can be categorized as "Platform as a Service" tools.

Some of the features offered by Paz are:

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

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

• Fast and secure. The entire process is really simple with no special tools needed, just a simple git push.
• Scaling in Tsuru is completely painless. Just add a unit and Tsuru will take care of everything else.
• Tsuru is built to be extensible. Through services you can provide anything your application needs.

Paz and tsuru are both open source tools. It seems that tsuru with 3.14K GitHub stars and 421 forks on GitHub has more adoption than Paz with 6 GitHub stars and 4 GitHub forks.
