SaaS / On Premise
|
Offers a free plan |
Yes 1,300 service minutes every month. Plans to release a free tier for open source projects. |
Yes Very generous free plans for both the SaaS version as well as the on premise version. |
Predictable pricing |
Yes Semaphore doesn't have traditional pricing tiers, instead it lists the types of machines you can use and their pricing per second of service. They plan to release an annual plan at some point. |

Support / SLA |
N/A Not clear if they offer any real SLA on support. |
Yes All paid plans include next business day support. |
Paralellism
Every CI servers tends to address this differently (parallel, distributed, build matrix). Some of it is just marketing, and some is just nuance. For this table, parallel means that tasks can be run concurrently on the same machine, distributed means that tasks can be scaled horizontally, on multiple machines How to split tests in parallel in the optimal way with Knapsack Pro |
Yes Allows defining a custom build matrix such that your build can be parallelized accross several different environments. |
Yes Easily configure jobs you want to be run in parallel via the YML config file (gitlab-ci.yml) |
Distributed builds
distributed means that tasks can be scaled horizontally, on multiple machines How to split tests in parallel in the optimal way with Knapsack Pro |

Yes Allows defining complex build workflows with ease |
Yes Defined via YML config files |
Reports
Reports are about the abilty to see specific reports (like code coverage or custom ones), but not necesarily tied in into a larger dashboard. |

Specific language support: Ruby
Some CI servers have built-in support for parsing RSpec or Istanbul output for example and we mention those. Some others make it even easier by detecting Gemfiles or package.json and automate parts of the process for the developer. |
Yes Provides rich documentation on integrating Semaphore CI in Ruby projects. Also provides sudo access if you need to install system dependencies or C extensions. |
Yes Although not built into GitLab CI by default, the Docker support allows solving any Ruby specific need that may arise. |
Specific language support: JavaScript |
Yes Provides rich documentation on integrating Semaphore CI in Javascript projects |
Yes Although not built into GitLab CI by default, the Docker support allows solving any Javascript specific need that may arise. |
Integrations
1st party support for common tools (like Slack notifications, various VCS platforms, etc) |
Yes Integration with GitHub and Slack. They allow building iOS projects via their macOS Mojave VM image. |
Yes Plenty of third party integrations available throughout GitLab, most notably Kubernetes and GitHub, but also plenty of others: https://docs.gitlab.com/ee/integration/README.html |

Custom integreation is available, via an API or otherwise, it's mentioned separately as it allows further customization than any of the Ecosystem/Integration options |
