Docker Machine vs Vagrant: What are the differences?
What is Docker Machine? Machine management for a container-centric world. Machine lets you create Docker hosts on your computer, on cloud providers, and inside your own data center. It creates servers, installs Docker on them, then configures the Docker client to talk to them.
What is Vagrant? A tool for building and distributing development environments. Vagrant provides the framework and configuration format to create and manage complete portable development environments. These development environments can live on your computer or in the cloud, and are portable between Windows, Mac OS X, and Linux.
Docker Machine and Vagrant are primarily classified as "Container" and "Virtual Machine Management" tools respectively.
"Easy docker hosts management" is the top reason why over 12 developers like Docker Machine, while over 354 developers mention "Development environments" as the leading cause for choosing Vagrant.
Docker Machine and Vagrant are both open source tools. Vagrant with 18.6K GitHub stars and 3.74K forks on GitHub appears to be more popular than Docker Machine with 5.37K GitHub stars and 1.55K GitHub forks.
Shopify, SendGrid, and Starbucks are some of the popular companies that use Vagrant, whereas Docker Machine is used by Leftronic, Docker, and DNT. Vagrant has a broader approval, being mentioned in 802 company stacks & 475 developers stacks; compared to Docker Machine, which is listed in 43 company stacks and 46 developer stacks.

"The best way to ensure that local testing was possible was to normalize people’s dev environments. For this we chose Vagrant. This, combined with Chef, allows us to do our local dev in sandboxed Linux instances running locally via VirtualBox in a configuration as similar to production as possible. In addition to making dev environment setup much easier than it used to be, this ensures that each engineer has a consistent environment that is ready to run tests out of the box. The user SSHs into the local linux server and runs spec commands like they would on their host OS, and generally everything Just Works. Most people on our team combine this with Zeus, which allows the Rails environment to be preloaded for lightning fast (relatively speaking) test runs. Both Vagrant and Zeus have their share of issues, but in practice we’ve found them to be a huge time saver."
Not blazing fast but we pick Vagrant for all our projects because the console mode without gui leads to a low consumption of ram memory making it the best way for DevOps ready environment requiring less configuration.
Vagrant allows me to ensure that anyone I'm collaborating with will be able to test my web application in the same environment. I also use Vagrant to setup VMs that I can use to refine my Capistrano recipes.
We use Virtualbox in combination with Vagrant during development to ensure a consistent test/development environment. This helps to reduce the number of defects when our software goes to production.
Building development environments that closely match real world web environments, enabling more rapid and accurate testing and development.
