## What it is
Lumos is a cross-platform 2D and 3D game engine written in C++17, supporting Vulkan and OpenGL rendering with an ECS architecture and ImGui-based editor tooling. It builds on Windows, Linux, macOS, and iOS using Premake-generated project files.

## Use cases
- build a 2d or 3d game in c++
- cross-platform game engine with vulkan support
- open source game engine with ecs architecture
- learn how a game engine is built
- prototype games on windows linux and mac
- deploy a game to ios from c++

## When to choose
- you want a permissively licensed (MIT) C++ game engine you can modify
- you need Vulkan or OpenGL rendering across desktop and iOS
- you prefer an ECS-based engine with source access over large commercial engines

## When to avoid
- you need a production-proven engine with large ecosystem and asset store
- you want a no-code or scripting-first engine like Godot or Unity
- you need console platform support

## Facets
- artifact type: framework
- maturity: active
- function: game-engine, graphics, ui-components, simulation
- domain: graphics, cross-platform
- platform: windows, cpp, cross-platform
- tags: vulkan, opengl, ecs, imgui, premake, 2d-engine, 3d-engine, game-development, linux, macos, ios
