Godot Export Builds

This covers the full export pipeline for shipping Godot games to Windows, Linux, macOS, Android, iOS, and Web. It includes headless command-line exports for CI/CD, platform-specific gotchas like macOS notarization and Android signing, and practical scripts for GitHub Actions workflows, Steam uploads, and PCK patching for updates. The "NEVER" rules are worth reading if you've shipped a build that crashed on mobile but worked fine in editor, or accidentally committed a keystore to Git. Most useful when you're setting up automated builds or need to reduce your 500MB web export to something reasonable. The feature flag patterns help you strip debug commands from production without littering your code with conditionals.
