Which tool for which job

GitHub Copilot wins when you want GitHub's own coding agent in VS Code or another listed editor, including a free completion tier.

Summer Engine wins when you want to build and ship a real 2D/3D game with an AI-first engine rather than only generate assets for Unity or Unreal.
