AppVeyor vs AWS CodeBuild

AppVeyor provides continuous integration tools for Windows developers, with hosted service, self-hosted jobs and an Enterprise installation option for customer premises. A build pipeline can retrieve code, restore caches, install dependencies, build and test software, package artifacts, deploy, then run finalizer scripts. Projects can be configured through an appveyor.yml file or the user interface. Build matrices can create jobs across operating systems, variables, platforms, configurations, test categories and build clouds. Listed source control providers include GitHub, Bitbucket, GitLab, Azure DevOps, Kiln and Gitea. Deployment options include inline providers and environments triggered manually or through the API. The REST API covers teams, projects, builds, environments and deployments, with bearer-token authentication. Secure variables can be encrypted with account-specific keys and are not decoded during pull-request builds by default. Hosted builds use pristine virtual machines not shared with other builds, and VM state is not preserved. Every plan has a 60-minute maximum build-job execution time. Paid plans start at $29 a month.

AWS CodeBuild is a paid, cloud-hosted continuous integration service for compiling, testing, and packaging code from build scripts. It provisions and scales build capacity automatically, so projects do not require users to manage build servers. Preconfigured environments cover Java, Python, Node.js, Ruby, Go, Android, .NET Core for Linux, and Docker; teams can also supply Docker-based environments. A YAML build specification defines commands for each build phase and other settings. Builds can start from CodeCommit, GitHub, GitHub Enterprise, Bitbucket, Amazon S3, or CodePipeline, and can work with Jenkins. Artifacts can be stored in S3 or sent to an artifact repository. IAM provides access controls, while KMS keys encrypt artifacts. Build timing, status, commit ID, metrics, and logs are available through the service and CloudWatch, with SNS event notifications. A free plan provides stated monthly allowances; paid usage starts at 0.01 USD and can add charges for data transfer and related AWS services.
