| Type of product |
SaaS |
Self-hosted / On Premise |
| Offers a free plan |
Yes1,300 service minutes every month. Plans to release a free tier for open source projects. |
YesFree, open source software |
| 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. |
YesJenkins is free software, the only costs are those assigned to running your infrastructure. |
| Support / SLA |
N/ANot clear if they offer any real SLA on support. |
No (partial)No official support available, or SLAs. However, Jenkins' popularity ensures you'll find support in various places (official Jenkins forum, IRC, StackOverflow etc.) |
|
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. |
Yes (partial)Jenkins allows builds to be run in parallel, but all builds share the same environment and there can be issues arising from shared resources such as the filesystem. |
|
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 |
N/A |
Yes (partial)Jenkins has a concept of master server and agents, for distributing builds, but setting that up requires quite a bit of manual work from a sysadmin, compared to other options. |
| Containers support / Build environment |
YesAllows running builds inside docker containers |
No (partial)By default, Jenkins runs all builds in the same environment as the build server itself, which can lead to numerous issues and is generally not a good practice. Some plugins address this issue, but they need to be manually installed. |
|
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 via the Blue Ocean project (part of Jenkins): https://jenkins.io/doc/book/blueocean/dashboard/#dashboard |
|
Management support
How easy is it to manage users / projects / assign roles and permissions and so on |
Yes |
NoIn practice, for Jenkins it usually means that there's someone solely in charge of the Jenkins instance (configuration, management). Collaboration features built into other similar products are lacking, as are governance features (no easy way to tell from Jenkins alone _who_ is responsabile for a broken build, for example), even if your Version Control Server of choice can give that information (via `git blame` for example). |
| Self-hosted option |
No |
YesJenkins is Open Source Software, and self-hosting is the only way to use it. |
| Hosted plans / SaaS |
Yes |
NoOnly available for self-hosting. |
|
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 |
YesOffers extensive support for custom pipelines, either through the Jenkins Pipeline DSL, written in a Jenkinsfile, either through the Web UI. Also, their Blue Ocean project is a great tool for building pipelines: https://jenkins.io/projects/blueocean/ |
|
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 |
YesHas ready-made integrations for standard reports such as JUnit test results. |
|
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 |
> 1000 community pluginsThanks to it's popularity, there's a large selection of available plugins for Jenkins. They can all be easily browsed over at https://plugins.jenkins.io/. The downside is that almost anything you want to do in Jenkins requires installing a plugin, even core functionality such as parsing output or checking out source code. |
|
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. |
Yes (Partial)RSpec and Cucumber test suites can be integrated into Jenkins thanks to the large pool of available plugins and Ruby gems. Jenkins only understands the JUnit format natively. |
| Specific language support: JavaScript |
YesProvides rich documentation on integrating Semaphore CI in Javascript projects |
Yes (Partial)Jest, AVA and other test suites can be integrated into Jenkins thanks to the large pool of available plugins and NPM packages. Jenkins only understands the JUnit format natively. |
|
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. |
YesAllows integrations with other tools (ie: Slack, GitHub) or communication protocols (ie: email) via it's rich plugin suite |
|
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 |
YesFor use-cases that the +1k plugins don't cover, the Jenkins Remote API is yet another way to integrate Jenkins into your favorite tools or internal products. |
| Auditing |
Yes |
NoJenkins instances are really managed by a sole user with administrative privileges. This can lead to various issues when it comes to audit trails / accountability. |
| Additional notes |
List of features is based on Semaphore 2.0 |

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 :)
