Travis CI vs. Shippable vs. Snap CI

Free for open source projects, 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.com means you can effortlessly test your library or applications against multiple runtimes and data stores without even having all of them installed locally.

Shippable is a SaaS platform that lets you easily add Continuous Integration/Deployment to your Github and BitBucket repositories. It is lightweight, super simple to setup, and runs your builds and tests faster than any other service.

Snap CI is a cloud-based continuous integration & continuous deployment tool with powerful deployment pipelines. Integrates seamlessly with GitHub and provides fast feedback so you can deploy with ease.
