AWS CodeBuild vs GameCI

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.

GameCI provides free, open-source tools for automating game project builds, tests, and deployments. Unity is its primary maintained engine package, with official containers, GitHub Actions, licensing flows, build targets, and documentation. Its CLI also detects Unreal Engine and Godot projects and includes build commands for both; a plugin API can connect additional engines. Officially supported CI/CD platforms are GitHub Actions, GitLab CI, and CircleCI. Listed build targets include iOS, Android, Windows, macOS, Linux, and WebGL. For Unity, the Test Runner supports All, PlayMode, EditMode, and Standalone modes. Results can appear as GitHub status checks if the workflow has write permissions and a GitHub token, or be uploaded as artifacts. GameCI says it does not acquire or store Unity credentials supplied for activation during build and test steps. Self-hosting is described for bare-metal machines, virtual machines, or Orchestrator; operators handle operating-system configuration and lifecycle management. The project is maintained by volunteers and offers best-effort community support, not premium support. CI provider build minutes may cost extra.
