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

Bitbucket Pipelines

https://bitbucket.org/product/features/pipelines

Scrutinizer CI

https://scrutinizer-ci.com
Unique feature

Best Jira integration possible

Ongoing statical analysis

Type of product

SaaS / On Premise

SaaS

Offers a free plan

Yes

Offers a very modest free cloud plan, limited to 5 users, 50 minutes of build time per month and 1GB storage. There's no free self-hosted version, but they do offer a $10 one-time payment plan for 10 users (build time and storage is only limited by your infrastructure)

Yes

Free for open source projects

Predictable pricing

Yes

Pricing is based on amount of users for both the cloud and on premise versions. The cloud offering has different tiers depending on build times and storage.

Yes

Three different paid monthly tiers

Support / SLA

Yes

Dedicated tehnical 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

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

N/A

Documentation is unclear, but it's reasonable to assume that distributed builds for the on premise version are not an issue.

N/A

Unclear from the documentation (probably not)

Containers support / Build environment

Yes

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

Excellent overview and contextual feedback.

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

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

Large collection of available apps: https://confluence.atlassian.com/bitbucket/apps-and-integrations-675189068.html

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

Clear, concise documentation on setting up a Ruby project with Bitbucket pipelines: https://confluence.atlassian.com/bitbucket/ruby-with-bitbucket-pipelines-872005618.html

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

Clear, concise documentation on setting up a Javascript project with Bitbucket pipelines: https://confluence.atlassian.com/bitbucket/javascript-node-js-with-bitbucket-pipelines-873891287.html

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

Large collection of available integrations: https://confluence.atlassian.com/bitbucket/apps-and-integrations-675189068.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

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

There's some confusion regarding Bitbucket Pipelines and Bamboo, where they overlap and where not. Atlassian discontinued their Bamboo Cloud offering ~3 years ago, so at a high-level they are different products in that regard. What can be said about both is that they are top-tier tools for high-demand engineering teams, especially valuable as long as the other tools in the Atlassian suite are adopted (Bitbucket is a must for Bitbucket pipelines, being just one if it's features, but other tools like Jira are not to be dismissed either). It does seem like Bitbucket Pipelines is the more mature product of the two though.

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