Scrutinizer CI

https://scrutinizer-ci.com
Unique feature

AutoDev Ops / Allows keeping code management and CI in the same place

Ongoing statical analysis

Type of product

SaaS / On Premise

SaaS

Offers a free plan

Yes

Very generous free plans for both the SaaS version as well as the on premise version.

Yes

Free for open source projects

Predictable pricing

Yes

Clear and affordable pricing for both SaaS and self-hosted versions.

Yes

Three different paid monthly tiers

Support / SLA

Yes

All paid plans include next business day support.

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 the optimal way with Knapsack Pro

Yes

Easily configure jobs you want to be run in parallel via the YML config file (gitlab-ci.yml)

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 the optimal way with Knapsack Pro

Yes

N/A

Unclear from the documentation (probably not)

Containers support / Build environment

Yes

The Docker Container Registry is integrated into GitLab by default

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

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

Yes

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

Self-hosted option

Yes

No

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

Defined via YML config files

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

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

Although not built into GitLab CI by default, the Docker support allows solving any Ruby specific need that may arise.

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

Although not built into GitLab CI by default, the Docker support allows solving any Javascript specific need that may arise.

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

Plenty of third party integrations available throughout GitLab, most notably Kubernetes and GitHub, but also plenty of others: https://docs.gitlab.com/ee/integration/README.html

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

Provides a REST API and a (new) GraphQL API, with plans to maintain the GraphQL API only going forward. Allows doing almost anything that can be done via the interface, at least in terms of CI needs.

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 Auto DevOps feature might be interesting to people looking for a very hands-off experience with getting a CI/CD process up and running https://docs.gitlab.com/ee/topics/autodevops/

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