Ansible needs python, which is present by default on most Linux distributions.
The Atlassian implementation of Git-Hub that integrates with Jira and associated tools.
Takes a yaml definition for an API and turned it into a nicely formatted HTML spec document for the API.
Calabash is a tool for automating testing, using cucumber, on iOS and Android platforms.
Cucumber is an automated test suite that can also write your specification documentation as it tests, so you have a single source of truth for how your application’s specifications.
Unlike Ansible, Chef needs Ruby to operate, Ruby and Gems are not part of the default distribution and therefore must first be installed before it works.
Chocolatey builds on Powershell to provide unattended installation and works with most existing software installation technologies like MSI, NSIS, InnoSetip, but also works with runtime binaries and zip archives.
Think of it as yum (RedHat) or apt (Debian/Ubuntu) for Windows
Console is a Service Discovery and Configuration tool from Hashicorp. With Multi-datacentre scaling, failure detection and key value configuration storage this is fast becoming a useful tool, like many of the others from HashiCorp.

Elasticsearch is a search engine based on Apache Lucene. It provides a distributed, multitenant-capable full-text search engine with an HTTP web interface and schema-free JSON documents. Not strictly a DevOps tool, but when used in conjunction with LogStash and Kibana, forms what’s currently referred to as an ELK stack, which is capable of ordering your system log/errors effortlessly.
Git is a free and open source distributed version control system designed to handle everything from small to very large projects with speed and efficiency.
It’s easy to learn, has a tiny footprint and lightning fast performance.
It outclasses Source Control Management tools like Subversion, CVS, Perforce, and ClearCase with features like cheap local branching, convenient staging areas, and multiple workflows.
An open platform for displaying analytics and monitoring data. Commonly used with Elastic-Search to replace Kibana for data dashboards/
Grok is not specifically an application, but actually a filter in LogStash, which allows you to turn unstructured data into structured data for use in Elastic-Search and Kibana.

Jenkins (previously known as Hudson)
An open source automation server that is written in Java. The project was forked from Hudson after a dispute with Oracle.
Jenkins helps to automate the non-human part of the whole software development process with now common things like continuous integration and by empowering teams to implement the technical aspects of continuous delivery. It is a server-based system running in a servlet container such as Apache Tomcat. It supports version control tools, including AccuRev, CVS, Subversion, Git, Mercurial, Perforce, Clearcase and RTC, and can execute Apache Ant, Apache Maven and sbt based projects as well as arbitrary shell scripts and Windows batch commands. The creator of Jenkins is Kohsuke Kawaguchi. Released under the MIT License, Jenkins is free software.
An open-source system for automating deployment, scaling and management of containerized applications that was originally designed by Google and donated to the Cloud Native Computing Foundation.

Platform agnostic Cloud Application Management software.
This a commercial product with great looking graphical representations of your cloud infrastructure. This is in direct competition with open source solutions like Terraform.
RedHat’s technology for building containerised services based on Docker and Kubernetes
Another HashiCorp creation. Packer is an easy to use and automation tool for the creation of machine images of any type. Embracing modern configuration management it encourages you to use a framework like Chef or Puppet to install and configure the software within your Packer-made images.
An open source build tool for Scala and Java projects, similar to Java’s Maven or Ant.
Cucumber for .Net
Swagger is the world’s largest framework of API developer tools for the OpenAPI Specification(OAS), enabling development across the entire API lifecycle, from design and documentation, to test and deployment.
