Bamboo vs Drone comparison of Continuous Integration servers
What are the differences between Bamboo and Drone?

Bamboo

Drone

https://drone.io
Unique feature

Atlassian suite integration

Customization

Type of product

On Premise

SaaS / On Premise

Offers a free plan

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.

Yes

The cloud version is free for open source projects. Also offers a free plan for any project, with a limit of 5000 builds per year. The on-premise version is available as a Docker image.
Predictable pricing

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.

Yes

Predictable pricing based on number of users and repositories. They have a calculator to help determine cost.
Support / SLA

Yes

Dedicated tehnical support.

N/A

It's not clear what their support commitment is. They have a fairly active community on Discourse, for community 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 optimal way with Knapsack Pro

Yes

Up to 100 parallel agents

Yes

Pipeline task configuration allows running tasks in parallel
Distributed builds
distributed means that tasks can be scaled horizontally, on multiple machines
How to split tests in parallel in optimal way with Knapsack Pro

Yes

Agents can run on multiple machines.

Yes

Pipelines can be configured to run on multiple machines, although they recommend that to be an option only if paralellizing tasks and scaling vertically doesn't suffice. They even support multi-platform distribution (ie: running tasks on various operating systems)
Containers support / Build environment

Yes

By default, they offer Docker support for the CI/CD job runners.

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 dashboards, even more so thanks to integrations with the other tools in the Atlassian arsenal

Yes

Management support
How easy is it to manage users / projects / assign roles and permissions and so on

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)

Yes

They offer in-depth documentation for user and server management. A lot of it can be done via the drone CLI tool, which seems to be the focal point of the docs.
Self-hosted option

Yes

Yes

Hosted plans / SaaS

No

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

Advanced pipeline support - with features built for feature branch support, various triggers, schedules, external notifications and more.

Yes

Easily configurable pipelines via 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

N/A

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 selection (~200) of apps that integrate with Bamboo, available on the official marketplace for Bamboo: https://marketplace.atlassian.com/addons/app/bamboo

Yes

Drone CI allows integrating plugins into the CI/CD process. They have a list of available community plugins and provide documentation on building your own. Plugins are Docker containers which plug directly into the CI/CD process.
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 (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

No (partial)

No specific support, but they do provide sufficient documentation on getting a Ruby project up and running, including a multi-platform example.
Specific language support: JavaScript

No

No specific support, beyond some documentation on integrating Selenium (not marked as partial support since that documentation is only promoted in the Atlassian docs, but is hosted by BrowserStack)

No (partial)

No specific 1st party support, but the plugin marketplace features an NPM authoring and an NPM authentication plugin.
Integrations
1st party support for common tools (like Slack notifications, various VCS platforms, etc)

Yes

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

Yes

Integrates well with source code management platforms (1st party support for GitHub, GitLab, BitBucket) as well as other systems via 3rd party plugins.
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

Drone provides a feature-rich REST API, as well as an official Go SDK for it.
Auditing

Yes

Yes

Additional notes

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

The fact that Drone works with any source code manager, as well as the fact that it can run tasks on multiple platforms makes it stand out from the rest. Very nifty!

How to run parallel tests on Bamboo and Drone
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 Bamboo and Drone 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'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 :)
