Travis CI
- Snippet from Wikipedia: Travis CI
Travis CI is a hosted continuous integration service used to build and test software projects hosted on GitHub, Bitbucket, GitLab, Perforce, Apache Subversion and Assembla.
Travis CI was the first CI service that provided services to open-source projects for free but as December 2020 no longer does so. TravisPro provides custom deployments of a proprietary version on the customer's own hardware.
The source is technically free software and available piecemeal on GitHub under permissive licenses. The company notes, however, that the large number of tasks that a user needs to monitor and perform can make it difficult for some users to successfully integrate the Enterprise version with their own infrastructure.
