AWS CodeBuild vs Google Cloud Build comparison of Continuous Integration servers

	AWS CodeBuild https://aws.amazon.com/codebuild/	Google Cloud Build https://cloud.google.com/cloud-build/
Unique feature	AWS integration	Security / speed
Type of product	SaaS	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.	Yes Google offers a generous 120 build-minutes per day plan, not including time spent waiting in the queue.
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.	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	Yes Even available as a paid add-on, for 24/7 phone support for example: https://cloud.google.com/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	N/A	Yes
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	N/A
Containers support / Build environment	Yes Builds run in specific-to-the-project, isolated environments	Yes Native Docker and Packer support
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.	Yes
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/	Yes
Self-hosted option	No	No (partial) While there's no self hosted variant, they provide a local Cloud Build image which allows you to build locally, very valuable for debugging.
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 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	Yes Configurable via YML and/or JSON 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 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.	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?	N/A	Yes There are predefined images built for Cloud Build, which can be integrated right away in your build process. Some of them are first party: https://github.com/GoogleCloudPlatform/cloud-builders and others are community contributed: https://github.com/GoogleCloudPlatform/cloud-builders-community
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	N/A Nothing specific as far as we can tell
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	Yes (partial) npm, yarn and jasmine-node support via predefined Cloud Build steps.
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/)	Yes Various integrations available via custom Build Steps, as well as natively (Kubernetes, Docker, etc.)
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	Yes REST API and comprehensive CLI tool, as well as a pub/sub system for build notifications.
Auditing	Yes	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.	Not unlike other Google tools, there's a strong emphasis on allowing developers to build on top of the service. Becomes more valuable if you're using other Google Cloud services as well.
