Unique feature

Ongoing statical analysis

N/A

Type of product

SaaS

SaaS / On Premise

Offers a free plan

Yes

Free for open source projects

Yes

Free unlimited builds for open source projects, 150 builds per month for all others (hosted plan). For the on-premise solution they only offer a 30 day trial.
Predictable pricing

Yes

Three different paid monthly tiers

Yes

Clear pricing based on number of concurrent jobs. They also allow a varied combination of platforms you want to run (Ubuntu, Windows, MacOS, CentOS) and provide a Bring Your Own Node option (so you can run builds on your own infrastructure)
Support / SLA

N/A

Not specifically mentioned, probably not.

Yes

One of the few competitors to offer support tiers with clearly defined SLAs: https://www.shippable.com/premium-support.html as well as Services and Training: https://www.shippable.com/devops-services.html
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

Automated parallalelization for code analysis, as well as support for running tasks in parallel

Yes

One thing that stands out, is the shipctl CLI tool, which can automatically determine which tests to run in parallel, based on previous performance, such that a minimal amount of time is ensured: http://docs.shippable.com/ci/running-parallel-tests/#running-tests-in-parallel
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

Unclear from the documentation (probably not)

N/A

No specific mention. From the wording, multiple environments are certainly available, but it's unclear if the tasks can be distributed to multiple containers/VMs on the same machine, or multiple machines.
Containers support / Build environment

Yes

Tests run in isolated containers. Docker support available.

Yes

Native Docker support
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

Besides classic CI overview, they also provide static code analysis insights, which is a differentiator for Scrutinizer

Yes

Detailed statistics available at multiple levels (job, account, project, etc.). They also include a view they call SPOG (Single Pane of Glass) which allows viewing a real-time representation of all of the pipelines in the organization, from where you can drill-in to the leaf nodes you're interested in.
Management support
How easy is it to manage users / projects / assign roles and permissions and so on

Yes

Additional seats available for every plan at $14.90 per seat, per month.

Yes

Self-hosted option

No

Yes

Hosted plans / SaaS

Yes

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

Pipelines as code (YML files)

Yes

Configurable via an YML file (called Assembly Lines)
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?

No

Yes

https://www.shippable.com/integrations.html
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

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/

Yes

Ruby is available by default on the Shippable container images. They also provide support for tools such as Cucumber or RSpec. Specific documentation for Ruby available on the website: http://docs.shippable.com/ci/ruby-continuous-integration/
Specific language support: JavaScript

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.

Yes

Specific documentation for Node.js available: http://docs.shippable.com/ci/ruby-continuous-integration/
Integrations
1st party support for common tools (like Slack notifications, various VCS platforms, etc)

Yes

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

Yes

http://docs.shippable.com/ci/ruby-continuous-integration/
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

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

Yes

Provides a straight-forward REST API: http://docs.shippable.com/platform/api/api-overview/. They also provide ways to integrate notifications in your workflow, via webhooks or specific channels (IRC, Slack, Email, etc): http://docs.shippable.com/ci/send-notifications/
Auditing

N/A

Unclear from the documentation, but most likely available.

Yes

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 Scrutinizer CI and Shippable
to execute 1-hour test suite in 2 minutes?

Without Knapsack Pro

you have to wait 20 minutes for slow tests running too long on the red node

Loading...

Run fast parallel CI build with Knapsack Pro

CI build completes work in only 10 minutes because Knapsack Pro ensures all parallel nodes finish work at a similar time

Loading...

You can even run 20 parallel nodes to complete your CI build in 2 minutes

How it works

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

Diagram that shows files distributed to 3 parallel CI nodes


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.

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 scalable 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 :)
