A new category of game engine, purpose-built for a world where NPCs talk, headsets are mainstream, and the browser is a first-class runtime. One API. Three targets. Ten thousand capabilities.
Unity, Unreal, and Godot were architected before ChatGPT, before the Quest Pro, and before WebGPU. RakuAI was designed from day one around all three.
Call the same REST endpoints from the browser, from a native Windows client, or from an XR headset. No separate WebGL port, no stripped mobile SKU, no platform-specific gotchas. Build once, ship to web, native, and immersive simultaneously.
LLM-driven NPCs, on-device small language model inference, emotion modeling, and dialogue trees are first-class subsystems — not plugins bolted on after the fact. The engine was designed around agents that can see, think, and speak.
18 native subsystems. 10,328 engine functions. 9,500+ REST endpoints. Physics, rendering, XR, audio, animation, networking, scripting — the full surface area of a real engine, not a framework or a demo. Battle-tested and ready for production workloads.
Existing engines were built for a world of single-player desktop games rendered in native binaries. RakuAI is built for a world where every character talks, every headset ships with hand tracking, and every game is one link away in a browser tab. The foundations had to be different.
| Capability | RakuAI | Traditional Engines |
