kaigen3d: a C-based agent-native game engine with headless operation and automated QA
gdechichi · x · 2026-11-06
Responding to the argument that Epic is doubling down on AI and restructuring UE6 because agentic workflows could overtake existing engines, the author shows kaigen3d already does this.
Key features:
- Fully headless operation driven by agents
- Written in C for maximum performance
- All assets editable by agents, then cooked and compressed by the engine
- No built-in editor; users ask agents to build custom editors per game
- Modular architecture, fully customizable by agents
- Automated QA including input recording, screenshots, and video
- Automated profiling and optimization
- Package to all platforms from a single codebase
The author argues existing engines can't compete on iteration time and automation.
