What is GameCI?
TL;DR: GameCI is a toolbox for building Unity games, which contains a collection of Dockerized Unity Editors for different target platforms, and documentation to set up pipelines using GitLab CI and GitHub Actions. You can use GameCI with any CI platfrom that supports Docker, even with Codemagic. Alternatively, you can use Codemagic’s preinstalled Unity Editor, or install another version.
