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

Travis CI

https://travis-ci.org

Bitbucket Pipelines

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

Build Matrix, ease of use, GitHub integration

Best Jira integration possible

Type of product

SaaS, Self-hosted / On Premise

SaaS / On Premise

Offers a free plan

Yes

Free for open source projects

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)
Predictable pricing

Yes

Clearly defined monthly plans, depending on concurrent jobs needed.

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.
Support / SLA

Yes

Available via email, or dedicated online interface for paid plans.

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

TravisCI makes it very easy to split your build into different stages which are then run in parallel (ie: run integration tests separate from the unit tests). TravisCI calls this a build matrix: https://docs.travis-ci.com/user/build-matrix/. You can also very easily split tests accross several VMs using the knapsack_pro gem.

Yes

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

N/A

N/A

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

Yes

TravisCI runs each build in a isolated virtual machine. Pre-build packages include a few which support specific languages (Ruby and JavaScript included) or other software (Git, various databases), but vanilla packages such as Ubuntu Trusty are also available.

Yes

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

Available by default in Travis (this is what most of the web UI consists of)

Yes

Excellent overview and contextual feedback.
Management support
How easy is it to manage users / projects / assign roles and permissions and so on

N/A

Yes

Self-hosted option

Yes

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.

No

Specifically built around GitHub pull requests. Pipelines can be defined, but parts of the process need to be implemented separatelly in GitHub.

Yes

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 (partial)

No persistent storage eliminates the possibility of code coverage reports on TravisCI alone. There is support for integrated 3rd parties such as Coveralls for reporting code coverage.

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 plugin support in TravisCI, plugins for other tools

Yes

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

TravisCI is designed to be a simple way to integrate CI/CD in your workflow so it has a couple of features aimed at specific languages, such as Ruby, starting from pre-built containers (with RVM already installed, for example) all the way to automatically running specific platform commands (such as detecting a Gemfile in the root of the project and automatically bundling dependencies). TravisCI also builds a Ruby SDK for easier use of the API.

Yes

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

Yes

TravisCI is designed to be a simple way to integrate CI/CD in your workflow so it has a couple of features aimed at specific languages, such as Javascript, starting from pre-built containers (with node already installed, for example) all the way to automatically running specific platform commands (such as detecting a package.json in the root of the project and running npm test)

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
Integrations
1st party support for common tools (like Slack notifications, various VCS platforms, etc)

Yes

By default, TravisCI is built to work with GitHub. Additionally, there is strong support for 3rd party tools like Coveralls, BrowserStack, etc.

Yes

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

Offers a feature-rich API that allows both reading data, as well as triggering or cancelling builds.

Yes

Auditing

N/A

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.

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 easy 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 :)
