AppVeyor vs GameCI

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.

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.
