## What it is
Heaps is a high-performance, cross-platform 2D and 3D game engine and graphics framework written in Haxe, created by the designer of the Haxe language. It compiles natively to HTML5/WebGL, desktop (OpenGL/DirectX via HashLink), mobile, and consoles, and includes 2D (h2d), 3D (h3d), resource management (hxd), and shader (hxsl) toolkits.

## Use cases
- build a cross-platform 2D game in Haxe
- create a 3D game with PBR materials and real-time shadows
- compile one game codebase to HTML5, desktop, and mobile
- write custom GPU shaders in Haxe syntax
- render large particle effects with GPU acceleration
- make a web game with WebGL
- ship a game to Nintendo Switch or PlayStation

## When to choose
- you want a free, open-source engine with no revenue share
- you're comfortable with Haxe and want fast compile-and-run cycles
- you need one codebase targeting web, desktop, mobile, and consoles
- you want proven production use (Dead Cells, Northgard, Wartales)

## When to avoid
- you prefer a large asset store and visual editor like Unity or Unreal
- your team only knows C# or C++ and won't learn Haxe
- you need extensive third-party plugin ecosystems
- you target platforms outside Heaps' supported list
