Unique feature	Best Jira integration possible	Atlassian suite integration
Type of product	SaaS / On Premise	On Premise
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 The full Atlassian suite is free for open source projects (https://www.atlassian.com/software/views/open-source-license-request). For all others, they offer a minimal free trial.
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 They price their product based on number of build agents (more concurrency, more expensive). Given the notoriety and depth of the Atlassian suite, the pricing can be steep for small companies.
Support / SLA	Yes Dedicated tehnical support.	Yes Dedicated tehnical support.
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 Up to 100 parallel agents
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 Documentation is unclear, but it's reasonable to assume that distributed builds for the on premise version are not an issue.	Yes Agents can run on multiple machines.
Containers support / Build environment	Yes	Yes By default, they offer Docker support for the CI/CD job runners.
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 Excellent dashboards, even more so thanks to integrations with the other tools in the Atlassian arsenal
Management support How easy is it to manage users / projects / assign roles and permissions and so on	Yes	Yes Great management support, built for large scale companies, even allows setting per-environment permissions (ie: QA team can only deploy to their own, isolated environment)
Self-hosted option	Yes	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	Yes Advanced pipeline support - with features built for feature branch support, various triggers, schedules, external notifications and more.
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	Yes Large selection (~200) of apps that integrate with Bamboo, available on the official marketplace for Bamboo: https://marketplace.atlassian.com/addons/app/bamboo
Specific language support: Ruby Some CI servers have built-in support for parsing RSpec or Istanbul output for example and we mention those.

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 (partial) It looks like the documentation and features for Ruby are lagging behind. All I could find is this repo: https://github.com/drscream/bamboozled-ruby-plugin, following this support ticket: https://jira.atlassian.com/browse/BAM-10948 from this documentation stub page: https://confluence.atlassian.com/bamboo0601/getting-started-with-ruby-and-bamboo-935580774.html

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 Deep integration with the Atlassian product stack (Jira, etc.).

Auditing	Yes	Yes
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.	Not really something that should be purchased separatelly from the Atlassian stack.
