Scrutinizer CI vs TeamCity comparison of Continuous Integration servers
What are the differences between Scrutinizer CI and TeamCity?

Scrutinizer CI

https://scrutinizer-ci.com

TeamCity

https://www.jetbrains.com/teamcity/
Unique feature

Ongoing statical analysis

Technology awareness

Type of product

SaaS

On Premise

Offers a free plan

Yes

Free for open source projects

Yes

They offer a great free professional plan, limited to 100 build configurations and 3 build agents. From there, you pay for each aditional agent you want (discounts if you purchase more than 1 agent at a time). They also provide a free plan for open source, non commercial projects, and steep 50% discounts for startups.
Predictable pricing

Yes

Three different paid monthly tiers

Yes

They have a clear list of prices per number of agents.
Support / SLA

N/A

Not specifically mentioned, probably not.

Yes

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

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

Yes

Distributed builds
distributed means that tasks can be scaled horizontally, on multiple machines

N/A

Unclear from the documentation (probably not)

N/A

No specific mention that we could find, but judging by the wording used it would appear that tasks can be divided accross different machines.
Containers support / Build environment

Yes

Tests run in isolated containers. Docker support available.

Yes

First class Docker support, among others
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

Great system overview, even allows building your own dashboards in order to see everything you're interested in at a glance.
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

Allows assigning roles, LDAP and Windows domain integrations and more.
Self-hosted option

No

Yes

Hosted plans / SaaS

Yes

No

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

Unlike most options in the CI/CD space, TeamCity allows defining pipelines using a Kotlin-based DSL. This unlocks a lot of potential, such as templates for common CI/CD tasks, and deep integration with various IDEs (not just JetBrains IDEs)
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

Something that stands out from the rest, allows integrating third party reports, as long as they produce HTML output.
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

JetBrains has a rich ecosystem of plugins in general.
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

Using what they call 'Technology Awareness', promises great intehration with Ruby projects, with features such as testing framework support, static analysis and code coverage available out of the box, with no additional work required: https://www.jetbrains.com/teamcity/features/technology_awareness.html
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.

No (partial)

Unlike Ruby, there's no first class support for Javascript, although they do advertise the fact that their large collections of plugins can cover any use case for Javascript projects: https://plugins.jetbrains.com/teamcity
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

Great cloud integrations (Google Cloud, AWS, VMWare, etc) as well as 'key' integrations (VSCode, Jira, even NuGet)
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

Unlike most tools, which offer just a Rest API, TeamCity provides ample opportunity for extension via plugins, their own API, and service messages (formatted messages on stdout)
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

Great ecosystem, with a strong focus on integration with other tools (not only JetBrains).

How to run parallel tests on Scrutinizer CI and TeamCity
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 Scrutinizer CI and TeamCity 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 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 :)
