Browser-Based Game Engine
Uruk
Engine
AAA game development platform with AI-powered world building, next-gen WebGPU rendering, and a complete content creation pipeline, all running in your browser.
Next-Gen Rendering
WebGPU-Powered Render Pipeline
A multi-layer rendering architecture with WebGL2 and WebGPU dual backends, custom render graph, and GPU-driven compute systems. Four pillars of visual fidelity running in your browser.
Capabilities
Everything You Need
A complete game development environment — from world building to AI-driven NPCs, from physics simulation to cinematic sequencing.
Entity Component System
Typed World, Entity, Component, and System architecture with per-phase step loops and real-time stats collection for every subsystem.
World Streaming
Cell-based streaming with real lifecycle management — dormant, loading, loaded, active, unloading. 12 cells covering the ancient city of Uruk.
AI Navigation
A* pathfinding on a 42-node waypoint graph with cell-gated traversal. 8-state FSM agents with patrol routes and daily schedules.
Physics Engine
AABB, sphere, and mesh colliders with trigger volumes, overlap detection, raycast, and character controller registry.
Blueprint Editor
Visual node-graph canvas with 12 node types across 5 categories, pin-type validation, drag-and-drop, zoom/pan, and execution preview.
Terrain Sculptor
Brush tools for raise, lower, smooth, flatten, noise, and erosion. Texture splatting with 3D wireframe preview.
Cinematic Sequencer
Timeline with keyframe tracks for camera, lighting, crowd, weather, and dialogue. Full playback controls for in-engine cinematics.
Mission Editor
Visual node-graph showing missions with dependency arrows, draggable nodes, objective trees, and chapter organization.
Desktop App
Electron shell for Windows, macOS, and Linux packaging. Run the full engine offline with native file system access.
AI Integration
Build Worlds with Natural Language
Uruk AI is the engine's strongest differentiator — an LLM integrated directly into the editor that manipulates the scene graph through natural language commands. Spawn NPCs, change weather, build structures, and design missions — all through conversation.
Built-In Code Editor
A Complete IDE in Your Browser
A full code editor with file explorer, syntax highlighting, and split/fullscreen modes — embedded directly in the engine. Browse the project structure, edit routers, tweak AI prompts, and modify game logic without leaving the browser.
2D → 3D Pipeline
Historically Accurate Character Art
Design characters grounded in Mesopotamian history. Choose from four historical period presets spanning 2,000 years, customize clothing, skin tone, hair, and accessories — then generate full-body concept art with AI and send it straight to the 3D pipeline.
Forge 3D Studio
Image to 3D in One Click
Uruk Forge 3D is a complete 3D content creation studio. Upload a 2D image or describe a character, and the engine reconstructs a high-poly textured mesh with PBR materials — ready for rigging, animation, and export directly into the game.
How We Compare
Engine Comparison
An honest look at where Uruk Engine leads, where it competes, and where established engines have the advantage.
