Hosted continuous integration

Warning: please be aware that Travis CI, which is mentioned in this article, has a security issue with its Free Tier service. By design, “secret” data such as access credentials are exposed within historical clear-text logs which are accessible by anyone via the Travis CI API. Please see this article for more information.

Repositories such as SourceForgeGitHub, and Launchpad, offer a wide range of tools that are useful for software development. These include wikis, e-mail lists, issue trackers and revision control. There are now complemented by a number of service providers who are offering support for automated build-and-test or continuous integration.

Using a continuous integration server that is hosted by a third-party can potentially be more convenient and cost effective than acquiring a server and setting up the continuous integration infrastructure yourself. This convenience could, in turn, make it easier for you to adopt a systematic approach to software testing to help ensure that your software is correct, robust and scalable.

The following table lists service providers who offer hosted continuous integration. Many of these exploit the capabilities of cloud computing to deliver their services.

Please remember that, when choosing to rely on a third-party to host a continuous integration server, the reliability, longevity, cost, usability and sustainability of the provider's service should be considered. Much of our advice on choosing a repository for your software project is also relevant to choosing a continuous integration server.
