## What it is
Urho3D is a free, lightweight, cross-platform 2D and 3D game engine written in C++17, licensed under MIT. It supports scripting with AngelScript and can build games for desktop, mobile, and web platforms.

## Use cases
- build a 2D or 3D game in C++
- lightweight open-source game engine for cross-platform games
- script game logic with AngelScript
- compile games to run in the browser via WebAssembly
- learn game engine internals
- make mobile games with a free MIT-licensed engine

## When to choose
- you want a lightweight, MIT-licensed C++ game engine
- you need cross-platform 2D/3D support including web export
- you prefer a small, hackable engine over large commercial ones

## When to avoid
- you need a actively developed engine with ongoing feature work - consider the Dviglo fork or Turso3D
- you need a large ecosystem, asset store, or commercial support
- you want a high-level engine with visual editors like Unity or Godot
