## What it is
ezEngine is a free, open source C++ game engine with a modular, plugin-based architecture and a feature-rich editor. It provides a full ECS scenegraph, rendering (D3D11 and Vulkan), physics, sound, visual scripting, and well-tested base libraries usable as a foundation for custom technology.

## Use cases
- build a 3d game in c++
- open source game engine alternative to unity
- prototype games with visual scripting
- foundation libraries for building a custom engine
- ecs based game engine for windows
- learn how a game engine works internally

## When to choose
- you want full C++ access and a modular engine you can strip down or extend
- you need a solid, unit-tested foundation (containers, scenegraph, resource streaming) for custom tech
- you develop primarily on Windows and want a complete editor with visual scripting
- you want to replace engine subsystems like physics or sound with your own plugins

## When to avoid
- you need full engine features on Linux or macOS, where only base libraries are fully functional
- you want a beginner-friendly engine with a large asset store and community like Unity or Godot
- you target consoles without arranging unofficial ports through third parties
- you prefer not to build from source, since prebuilt releases are infrequent
