Browser-Based Game Engine
Uruk
Engine
AAA game development platform with 25+ AI actions, 60+ mode tools, SSE streaming, WebGL2 + WebGPU dual-backend rendering, and 22 integrated subsystems — all running in your browser. 6,659+ tests passing.
Next-Gen Rendering
WebGPU-Powered Render Pipeline
A multi-layer rendering architecture with WebGL2 and WebGPU dual backends, custom render graph, WGSL compute post-processing, per-pass GPU timing, instanced mesh batching, and quality presets. Six 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
PhysicsWorldV8: rigid body types, broadphase, CCD, contact manifold, solver, collision layers/masks, raycast/overlap, trigger zones, cell-streamed collider management.
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.
AI Co-Pilot
Full AI integration layer with 25+ cataloged actions, 60+ mode-specific tools, streaming responses, prompt library, cross-session memory, and playtest analysis.
AI Integration
Build Worlds with Natural Language
Uruk AI is the engine's strongest differentiator — a full AI integration layer with 25+ cataloged actions, 60+ mode-specific tools, streaming responses, a 30+ prompt library, cross-session memory, and real-time playtest analysis. All wired through a decoupled event bus.

Built-In Code Editor
A Complete IDE in Your Browser
A complete IDE in the browser with unified top bar, 12-mode tool shelf, command palette (Ctrl+P, 30+ commands), enhanced inspector with per-property reset, and full keyboard shortcut system. File history with version timeline, diff preview, and one-click restore.
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.
| Capability | Uruk Engine | Unreal 5 | Unity | Godot |
