Unique feature

AWS integration

Type of product

SaaS / On Premise

SaaS

Offers a free plan

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.

Yes

The AWS free-tier includes 100 build-minutes per month, on their smallest machine. It's unclear, but it seems like this applies only to the first year of service.

Predictable pricing

Yes

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

Yes (partial)

While it's clear what the cost is (priced per build-minute), figuring out costs can be a hassle, especially as the price can vary quite a bit depending on commits to the project.

Support / SLA

N/A

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

Yes

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

Pipeline task configuration allows running tasks in parallel

N/A

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

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)

N/A

Containers support / Build environment

Yes

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

Yes

Builds run in specific-to-the-project, isolated environments

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

Offers minimal information built in, but allows integrations with tools such as CloudWatch (another Amazon product), or streaming build information to your own API, for more in-depth analysis.

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

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.

Yes

Professional user management via AWS Identity and Access Management: https://aws.amazon.com/iam/

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

Easily configurable pipelines via YML files.

Yes

As it's usually the case with Amazon, CodeBuild simply provides the 'build' part of a true CI/CD system, while pipelines are managed via CodePipeline, another Amazon product: https://aws.amazon.com/codepipeline/pricing/?nc=sn&loc=3

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.

N/A

Yes

Offers minimal information built in, but allows integrations with tools such as CloudWatch (another Amazon product), or streaming build information to your own API, for more in-depth analysis.

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

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.

N/A

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.

No (partial)

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

No (partial)

The environments available on CodeBuilt include Ruby pre-installed: https://docs.aws.amazon.com/codebuild/latest/userguide/build-env-ref-available.html, but that seems to be as far as specific support goes

Specific language support: JavaScript

No (partial)

No specific 1st party support, but the plugin marketplace features an NPM authoring and an NPM authentication plugin.

No (partial)

The environments available on CodeBuilt include Node pre-installed: https://docs.aws.amazon.com/codebuild/latest/userguide/build-env-ref-available.html, but that seems to be as far as specific support goes

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

Yes

CodeBuild builds can be connected to sources such as GitHub or BitBucket, but being an Amazon Service, the deepest integrations are with other Amazon Code services (CodePipeline, CodeDeploy, and others: https://aws.amazon.com/products/developer-tools/)

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

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

Yes

Amazon SDKs can be used to interact with CodeBuild

Auditing

Yes

Yes

Additional notes

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!

Like most things Amazon, it becomes more valuable as you acquire and integrate various Amazon solutions, not necesarily as a standalone tool.
