Codeship vs. Semaphore vs. DotCi

Codeship runs your automated tests and configured deployment when you push to your repository. It takes care of managing and scaling the infrastructure so that you are able to test and release more frequently and get faster feedback for building the product your users need.

Whenever somebody pushes new code to GitHub, Semaphore immediately runs all tests on the corresponding branch. Every time you create a new branch, Semaphore builds it automatically. It also knows how to clean up when you delete it.

DotCi is a Jenkins plugin created by Groupon that makes job management easy with built-in GitHub integration, push-button job creation, and YAML powered build configuration and customization. It comes prepackaged with Docker support as well, which means bootstrapping a new build environment from scratch can take as little as 15 minutes. DotCi has been a critical tool for Groupon internally for managing build and release pipelines for the wide variety of technologies in their SOA landscape.
