Why choose AWS CodeBuild? See product overview

AWS CodeBuild

https://aws.amazon.com/codebuild/
Unique feature

AWS integration

Type of product

SaaS

Offers a free plan

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 (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

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

N/A

Containers support / Build environment

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

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

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

Self-hosted option

No

Hosted plans / SaaS

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

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.

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?

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)

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)

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

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

Amazon SDKs can be used to interact with CodeBuild

Auditing

Yes

Additional notes

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

Run tests in parallel on AWS CodeBuild in the optimal way and avoid bottleneck parallel jobs.
