CoreOS vs Rancher: What are the differences?

What is CoreOS? Linux for Massive Server Deployments. CoreOS is designed for security, consistency, and reliability. Instead of installing packages via yum or apt, CoreOS uses Linux containers to manage your services at a higher level of abstraction. A single service's code and all dependencies are packaged within a container that can be run on one or many CoreOS machines.

What is Rancher? Open Source Platform for Running a Private Container Service. Rancher is an open source container management platform that includes full distributions of Kubernetes, Apache Mesos and Docker Swarm, and makes it simple to operate container clusters on any cloud or infrastructure platform.

CoreOS can be classified as a tool in the "Operating Systems" category, while Rancher is grouped under "Container Tools".

"Container management" is the primary reason why developers consider CoreOS over the competitors, whereas "Easy to use" was stated as the key factor in picking Rancher.

Rancher is an open source tool with 11.9K GitHub stars and 1.34K GitHub forks. Here's a link to Rancher's open source repository on GitHub.

According to the StackShare community, Rancher has a broader approval, being mentioned in 89 company stacks & 37 developers stacks; compared to CoreOS, which is listed in 45 company stacks and 12 developer stacks.

What are some alternatives to CoreOS and Rancher?
Docker
The Docker Platform is the industry-leading container platform for continuous, high-velocity innovation, enabling organizations to seamlessly build and share any application — from legacy to what comes next — and securely run them anywhere
LinuxKit
LinuxKit, a toolkit for building custom minimal, immutable Linux distributions. Designed for building and running clustered applications, including but not limited to container orchestration such as Docker or Kubernetes.
Docker Swarm
Swarm serves the standard Docker API, so any tool which already communicates with a Docker daemon can use Swarm to transparently scale to multiple hosts: Dokku, Compose, Krane, Deis, DockerUI, Shipyard, Drone, Jenkins... and, of course, the Docker client itself.
Ubuntu
Ubuntu is an ancient African word meaning ‘humanity to others’. It also means ‘I am what I am because of who we all are’. The Ubuntu operating system brings the spirit of Ubuntu to the world of computers.
Mesosphere
Mesosphere offers a layer of software that organizes your machines, VMs, and cloud instances and lets applications draw from a single pool of intelligently- and dynamically-allocated resources, increasing efficiency and reducing operational complexity.
