Offers a free plan |
Yes1,300 service minutes every month. Plans to release a free tier for open source projects. |
YesFree for open source projects |
Predictable pricing |
YesSemaphore 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. |
YesBesides the seat (per-user access) you need to buy compute credits for running the build, priced differently depending on the machine you're running builds on. |
Support / SLA |
N/ANot clear if they offer any real SLA on 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 |
YesAllows defining a custom build matrix such that your build can be parallelized accross several different environments. |
YesThere are limits on how many tasks can be run in parallel for the free tier builds: https://cirrus-ci.org/faq/#are-there-any-limits |

YesAllows running builds inside docker containers |
YesAllows containers or VMs for every major operating system. |
Analytics / Status overview
Analytics and overview referrs to the ability to, at a glance, see what's breaking (be it a certain task, or the build for a specific project) |

Build pipelines
A continuous delivery pipeline is a description of the process that the software goes through from a new code commit, through testing and other statical analysis steps all the way to the end-users of the product. |
YesAllows defining complex build workflows with ease |
YesDefined 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. |
YesProvides rich documentation on integrating Semaphore CI in Ruby projects. Also provides sudo access if you need to install system dependencies or C extensions. |
No (partial)No specific support from what I can gather, but it does provide documentation for Ruby, including integration with the knapsack_pro gem. |
Specific language support: JavaScript |
YesProvides rich documentation on integrating Semaphore CI in Javascript projects |
NoNo specific support and no documentation on setting up a CI/CD process for a Javascript project. |
Integrations
1st party support for common tools (like Slack notifications, various VCS platforms, etc) |
YesIntegration with GitHub and Slack. They allow building iOS projects via their macOS Mojave VM image. |
YesIntegrates well with GitHub - the whole CI/CD process starts with a commit to a GitHub repo. |
API
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 |
No |
YesProvides a pretty nifty GraphQL API which allows querying the Cirrus CI Schema, as well as webhooks support for other types of custom integrations (such as Slack or IRC notifications, for example). They also added support for GitHub actions |
Auditing |
Yes |
N/AFrom what we can tell, there's no specific support for auditing changes in the Cirrus CI config (other than what is traceable via git commits to the YML config file) |
Additional notes |
List of features is based on Semaphore 2.0 |
Seems to be used by companies with a solid engineering background (Google) |
you have to wait 20 minutes for slow tests running too long on the red node
CI build completes work in only 10 minutes because Knapsack Pro ensures all parallel nodes finish work at a similar time
You can even run 20 parallel nodes to complete your CI build in 2 minutes
Step 1
Install Knapsack Pro client in your project
Step 2
Update your CI server config file to run tests in parallel with Knapsack Pro
Step 3
Run a CI build with parallel tests using Knapsack Pro
Knapsack Pro in Queue Mode splits tests in a dynamic way across parallel CI nodes to ensure each CI node finishes work at a similar time. Thanks to that, your CI build time is as fast as possible. It works with many supported CI servers.

We've been really enjoying Knapsack Pro, it's been saving us a ton of time.
My team at @GustoHQ recently added @KnapsackPro to our CI. It's pretty sweet... It makes your builds faster _and_ (this is almost the better bit) more consistent! Thank you for the awesome tool!

This is a fantastic product, it's been a total game-changer for us.
We are using CircleCI and we noticed that builds were being limited by the slowest parallelized container. Knapsack Pro was really easy to setup and we saw huge improvements right away. Thank you for making this tool!

Knapsack Pro has helped us build an insanely fast and scalable build pipeline with almost no setup or maintenance.
Knapsack Pro saves us hours of engineer waiting time every week, and is the best solution for keeping our tests load balanced that we've used to date.
I've been playing with Queue Mode. Love it! Wow, I love how fast it goes.
Awesome to see @NASA speeds up tests with #knapsack gem in https://t.co/GFOVW22dJn project! https://t.co/2GGbvnbQ7a #ruby #parallelisation

I just logged into my account expecting it to say that I needed to add a credit card and was so surprised and delighted to see the trial doesn't count usage by calendar days but by testing days! This is incredible! I love it!!!
I just wanted to say that I really appreciate that small but very huge feature. Thank you for being so thoughtful :)
