YesFree for open source projects |
YesFree for open source projects |
| Predictable pricing |
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. |
YesClearly defined monthly plans, depending on concurrent jobs needed. |
| Support / SLA |
N/ANot clear if they offer any real SLA on support. |
YesAvailable via email, or dedicated online interface for paid plans. |
|
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 |
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 |
YesTravisCI makes it very easy to split your build into different stages which are then run in parallel (ie: run integration tests separate from the unit tests). TravisCI calls this a build matrix: https://docs.travis-ci.com/user/build-matrix/. You can also very easily split tests accross several VMs using the knapsack_pro gem. |

| Containers support / Build environment |
YesAllows containers or VMs for every major operating system. |
YesTravisCI runs each build in a isolated virtual machine. Pre-build packages include a few which support specific languages (Ruby and JavaScript included) or other software (Git, various databases), but vanilla packages such as Ubuntu Trusty are also available. |

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) |
Yes |
YesAvailable by default in Travis (this is what most of the web UI consists of) |

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. |
YesDefined via YML config files |
NoSpecifically built around GitHub pull requests. Pipelines can be defined, but parts of the process need to be implemented separatelly in GitHub. |
|
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. |
N/A |
Yes (partial)No persistent storage eliminates the possibility of code coverage reports on TravisCI alone. There is support for integrated 3rd parties such as Coveralls for reporting code coverage. |
|
Ecosystem
Besides the official documentation and software, is there a large community using this product? Are there any community-driven tools / plugins that you can use? |
N/A |
No plugin support in TravisCI, plugins for other tools |
|
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. |
No (partial)No specific support from what I can gather, but it does provide documentation for Ruby, including integration with the knapsack_pro gem. |
YesTravisCI is designed to be a simple way to integrate CI/CD in your workflow so it has a couple of features aimed at specific languages, such as Ruby, starting from pre-built containers (with RVM already installed, for example) all the way to automatically running specific platform commands (such as detecting a Gemfile in the root of the project and automatically bundling dependencies). TravisCI also builds a Ruby SDK for easier use of the API. |
| Specific language support: JavaScript |
NoNo specific support and no documentation on setting up a CI/CD process for a Javascript project. |
YesTravisCI is designed to be a simple way to integrate CI/CD in your workflow so it has a couple of features aimed at specific languages, such as Javascript, starting from pre-built containers (with node already installed, for example) all the way to automatically running specific platform commands (such as detecting a package.json in the root of the project and running npm test) |
|
Integrations
1st party support for common tools (like Slack notifications, various VCS platforms, etc) |
YesIntegrates well with GitHub - the whole CI/CD process starts with a commit to a GitHub repo. |
YesBy default, TravisCI is built to work with GitHub. Additionally, there is strong support for 3rd party tools like Coveralls, BrowserStack, etc. |
|
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 |
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 |
YesOffers a feature-rich API that allows both reading data, as well as triggering or cancelling builds. |
| Auditing |
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) |
N/A |
| Additional notes |
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 :)
