PyreForge — Design. Build. Ignite.

Built on real engineering

Not a toy. A full engine with 70+ systems, 3D physics, AI agent orchestration, and a real-time game runtime.

Physics

Rapier 2D + 3D

Production-grade rigid body physics. Worker offload with SAB/transfer/main-thread fallback. Heightfields, convex hull, trimesh, joints, sensors, collision groups.

WASM + Web Worker

Scripting

QuickJS + Node Graph

Sandboxed QuickJS WASM with CPU/memory limits. Visual node graph with 50+ nodes and bi-directional code↔graph sync. AI generates gameplay scripts.

640KB memory cap

Rendering

PixiJS + Three.js + WebGPU

2D viewport with culling, sprite pooling, and LOD. 3D with shadows and ACESFilmic tonemapping. WGSL compute shaders for particles (1M).

Viewport culling

AI Pipeline

Anvil Copilot + Agent Team

Terrain editing, scene composition, proc-gen scripts, dialogue, playtest analysis. Three-agent orchestration with debate-based convergence. BYOK for 7 providers.

10 AI pipelines

Runtime

Game Kernel + HUD + Physics

Fixed-timestep loop (60Hz), camera follow, canvas health bars/minimap/dialogue, animation state machine, particle effects, save/load. Exported games under 150KB.

Zero-dependency runtime

3D Pipeline

Import → Physics → Export

GLB, FBX, OBJ import with auto mesh colliders. Animation state machine (idle/walk/run/jump/attack). Humanoid ragdoll rig. 3-tier export: GLB/WebPlay/Godot 3D.

Describe

Tell the AI what you want in plain English. "Add a haunted forest with NPCs and quests."

BEGINNER

{ }

Customize

Visual editor, terrain painter, asset library, marker placement. No code needed.

INTERMEDIATE

◈

Script

Node graph editor, event pages, custom behaviors. Connect events, conditions, and actions.

EXPERT

</>

Code

Power Studio: Monaco editor, terminal, AI copilot. Write code directly or let AI generate it.

POWER USER

Everything you need

A complete game development environment — 2D, 3D, AI, and real-time play testing.

Anvil Copilot

Context-aware AI that reads your project, edits terrain, places assets, writes scripts, and debugs logic. Multi-agent orchestration for complex tasks. Bring your own API key for 7 providers.

Real-Time Play Mode

Camera follow, WASD/gamepad/touch input, canvas HUD, dialogue overlay, pause menu, player save/load. Event-triggered particles and animation state machines.

14 Export Formats

Godot, Unity, HTML5, GLB, GLTF, WebPlay 3D, Godot 3D Scene, TMX, CSV, PNG, SVG, JSON, LDtk, Desktop (Tauri). Plus URL sharing with LZ compression — playable from a link.

Full 3D Pipeline

Import GLB/FBX/OBJ, auto-generate mesh colliders, physics joints, heightfield terrain, animation state machine, humanoid ragdoll rig. 3-tier export to GLB/WebPlay/Godot 3D.

Runtime Engine

Fixed-timestep kernel, camera system with shake, input abstraction, canvas HUD (health bars, minimap, dialogue), animation state machine, save/load. Exported games: sub-150KB.

AI Asset Generation

Generate sprites from text prompts via ComfyUI. Inpainting, img2img, IP-Adapter style locking. Generate entire sprite sheets, terrain tiles, and animation frames.

Power Studio

For power users: Monaco code editor, dockable tabs, integrated QuickJS terminal with live preview. AI generates code, you inspect and refine. Full engine API access.

AI-assisted + direct coding
