Travis CI is a hosted continuous integration service for the open source community. It integrats with GitHub or Bitbucket and offers first class support for:
Our CI environment provides multiple runtimes (e.g. Node.js or PHP versions), data stores and so on. Because of this, hosting your project on travis-ci.org means you can effortlessly test your library or applications against multiple runtimes and data stores without even having all of them installed locally.
travis-ci.org originally started as a service for the Ruby community in early 2011 but has added support for many other technologies since then.
In 2011, Paul & Allen got frustrated with the state of software testing and decided to solve the problem. CircleCI was founded with the mission of giving every developer state of the art automated testing and continuous integration tools.
CircleCI is by far the fastest way to run your tests (faster than your own servers, EC2, or other CI services). It offers facilities that don’t exist anywhere else, like the ability to SSH into our machines to debug your tests. And it automatically sets up new projects by inferring test settings, and splits your tests across multiple machines to get your code to customers in a fraction of the time.
Semaphore is a product of scratching our own itch. Rendered Text as a team of five people usually works on a few projects at a time. Although most of our projects are long term relationships, we take smaller projects that last two to three months. By bootstrapping applications over and over again we detected a pattern.
Setting up and maintaining a CI server with Jenkins or any other CI software is a pain and takes time, easily a day, even if you are developer with devops experience under your belt. Let me mention just a few things that you will have to worry about during CI server setup: SSH keys, hooks, iptables, SSL and user management. Even if you haven’t gone through the process of setting up CI you can imagine that it’s a tiresome process that you as a developer shouldn’t have to worry about. You should focus on your application!
Jenkins CI, in a nutshell, is the leading open-source continuous integration server. Built with Java, it provides over 400 plugins to support building and testing virtually any project.
Jenkins is an award-winning application that monitors executions of repeated jobs, such as building a software project or jobs run by cron. Among those things, current Jenkins focuses on the following two jobs:
Building/testing software projects continuously, just like CruiseControl or DamageControl. In a nutshell, Jenkins provides an easy-to-use so-called continuous integration system, making it easier for developers to integrate changes to the project, and making it easier for users to obtain a fresh build. The automated, continuous build increases the productivity.
Monitoring executions of externally-run jobs, such as cron jobs and procmail jobs, even those that are run on a remote machine. For example, with cron, all you receive is regular e-mails that capture the output, and it is up to you to look at them diligently and notice when it broke. Jenkins keeps those outputs and makes it easy for you to notice when something is wrong.
Codeship offers reliable continuous integration and deployment with a dead simple setup.
Codeship's CI service provides you with a simple hosted system to test every change you do in your application and if everything works we deploy to your staging or production environment. They're integrated with GitHub, Bitbucket, Heroku and Engine Yard, but you can also easily deploy to other PAAS providers and platforms.
