Ansible vs Capsule: What are the differences?
Developers describe Ansible as "Radically simple configuration-management, application deployment, task-execution, and multi-node orchestration engine". Ansible is an IT automation tool. It can configure systems, deploy software, and orchestrate more advanced IT tasks such as continuous deployments or zero downtime rolling updates. Ansible’s goals are foremost those of simplicity and maximum ease of use. On the other hand, Capsule is detailed as "Dead-Simple Packaging and Deployment for JVM Apps". Packages any JVM application, no matter how complex, as a single, plain executable JAR. A capsule may directly contain all of the application’s dependencies or simply declare some or all of them, to be downloaded when launched.
Ansible belongs to "Server Configuration and Automation" category of the tech stack, while Capsule can be primarily classified under "Java Build Tools".
Ansible and Capsule are both open source tools. It seems that Ansible with 37.8K GitHub stars and 15.8K forks on GitHub has more adoption than Capsule with 1.13K GitHub stars and 79 GitHub forks.

Ansible is the deployment tool for people who don't like deployment tools. It's close to scripting, doesn't pollute your servers with agents or centralized servers, and just makes immediate sense. The entire stack at Cloudcraft.co is orchestrated by Ansible. What does that mean? Beyond the obvious of installing packages and configuring services, Ansible coordinates all the machines into a working deployment: It adds API servers to the loadbancer pool, opens ports on the DB server for the backend servers to connect, gracefully upgrades services in a rolling fashion for zero-downtime deployments etc. And it's so easy to use, it's easier to use than doing things by hand, meaning it's a deployment tool you'll actually use every time!
We use Ansible to synchronize the few configuration-options we've taken on our CoreOS-Machines. This makes deployment even easier and the fact that it's Agentless made the decision even easier.
Ansible is used in both the development and production deployment process. A playbook couple with a Vagrantfile, easy deploys a local virtual machine that will mirror the setup in production.
I use Ansible to manage the configuration between all of the different pieces of equipment, and because it's agentless I can even manage things like networking devices all from one repo.
