Unique feature

Free, open source CI/CD server

Ongoing statical analysis

Type of product

On Premise

SaaS

Offers a free plan

Yes

Free, open source software. They provide some Enterprise add-ons and support at a cost though.

Yes

Free for open source projects
Predictable pricing

Yes

For the Enterprise plans, they specify very clear tiers depending on the number of pipelines (directly correlated with the size of the organization)

Yes

Three different paid monthly tiers
Support / SLA

Yes

Paid support available for enterprise plans

N/A

Not specifically mentioned, probably not.
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 optimal way with Knapsack Pro

Yes

Yes

Automated parallalelization for code analysis, as well as support for running tasks in parallel
Distributed builds
distributed means that tasks can be scaled horizontally, on multiple machines
How to split tests in parallel in optimal way with Knapsack Pro

Yes

They specify supporting tools like TLB (http://test-load-balancer.github.io/) which would require distributed builds.

N/A

Unclear from the documentation (probably not)
Containers support / Build environment

Yes

Native Docker and Kubernetes support

Yes

Tests run in isolated containers. Docker support 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

One of the greatest things about GoCD is their Value Stream Map which allows tracing every pipeline through every stage, from code commit, to testing and deployment. They also offer various dashboards for seeing status at a glance.

Yes

Besides classic CI overview, they also provide static code analysis insights, which is a differentiator for Scrutinizer
Management support
How easy is it to manage users / projects / assign roles and permissions and so on

Yes

Allows managing users, assigning roles, and even defining user groups with specific rights for certain pipelines.

Yes

Additional seats available for every plan at $14.90 per seat, per month.
Self-hosted option

Yes

No

Hosted plans / SaaS

No

Yes

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.

Yes

Fairly advanced support, from config files (YML, Groovy, JSON, etc) to API and UI interface for building and managing pipelines.

Yes

Pipelines as code (YML 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.

Yes

Yes

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?

Yes

Wide array of plugins available: https://www.gocd.org/plugins/#artifact (although they seem to pride themselves on the fact that most common operations / needs are first class citizens, so no plugins needed)

No

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

Available via plugins, such as the Gem repository poller: https://www.gocd.org/plugins/#package-repo

Yes

Code analysis (automated code reviews) are available for Ruby, as well as specific documentation for setting up a Ruby project: https://scrutinizer-ci.com/docs/guides/ruby. Frameworks like Ruby on Rails are supported. They also provide tools like bundler-audit, for identifying vulnerable gems: https://scrutinizer-ci.com/docs/tools/ruby/bundler-audit/
Specific language support: JavaScript

Yes

Available via plugins, such as the npm repository poller: https://www.gocd.org/plugins/#package-repo

Yes

Automated code reviews are available for Javascript as well as specific documentation for setting up a Node.js project: https://scrutinizer-ci.com/docs/guides/javascript. Typescript is also supported.
Integrations
1st party support for common tools (like Slack notifications, various VCS platforms, etc)

Yes

Integrations are also available via plugins (for notifications, LDAP authorization, Elastic agents and more): https://www.gocd.org/plugins/#notification

Yes

Light integration with third party systems, mainly code management frameworks like GitHub, Bitbucket, GitLab.
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

Yes

You can build on top of GoCD in a variety of ways, from writing custom plugins to using the CCTray feed provided by it.

Yes

Comprehensive REST API available: https://scrutinizer-ci.com/docs/api/
Auditing

Yes

N/A

Unclear from the documentation, but most likely available.
Additional notes

The code analysis features seem great, the offer for similar tools is quite light. Seems similar to lgtm.com

How to run parallel tests on GoCD and Scrutinizer CI
to execute 1-hour test suite in 2 minutes?

How it works

1. Install Knapsack Pro client in your project


2. Add Knapsack Pro client to your current CI server and run your tests in parallel



3. Update your CI server config file to run tests in parallel with Knapsack Pro

Knapsack Pro in Queue Mode will split tests in a dynamic way across parallel CI nodes to ensure each CI node finish work at a similar time. Thanks to that your CI build time is as fast as possible. It works with many supported CI servers.

Features that make your tests perform better

  • Queue mode see video

    Dynamic tests allocation across GoCD and Scrutinizer CI parallel jobs. Autobalance tests to get optimal test suite split betweeen CI nodes.

  • Regular mode see video

    Test suite split based on time execution. Generates subset of test suite per CI node before running tests.

  • Fallback mode

    Network issues? Not a problem, run tests anyway! Auto switch to the fallback mode to not depend on Knapsack Pro API.

  • All supported test runners

    Ruby: RSpec, Minitest, Test::Unit, Cucumber, Spinach, Turnip.

    JavaScript: Cypress.io, Jest

Trusted solution

Join the teams optimizing their tests with Knapsack Pro.

We've been really enjoying Knapsack Pro, it's been saving us a ton of time.

Devin Brown Software Engineer at Pivotal

This is a fantastic product, it's been a total game-changer for us.

Geoff Harcourt CTO at CommonLit

We are using CircleCI and we noticed that builds were being limited by the slowest parallelized container. Knapsack Pro was really east to setup and we saw huge improvements right away. Thank you for making this tool!

Martin Sieniawski Software Engineer at Collage

Knapsack Pro has helped us build an insanely fast and scaleable build pipeline with almost no setup or maintenance.

Tim Lucas Co-founder of buildkite.com

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.

Michael Amygdalidis Senior Software Engineer at Popular Pays

I've been playing with Queue Mode. Love it! Wow, I love how fast it goes.

Michael Menne CTO at humanagency.org

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 :)
