Flax Engine is a modern, multi-platform 3D game engine written in C++ and C# with full source code available. It provides an editor, real-time global illumination, visual scripting, and cross-platform deployment for Windows, Linux, macOS, Android, iOS, consoles, and web.

Use cases

  • build a 3D game with C# and C++ scripting
  • create a cross-platform game for PC, mobile, and consoles
  • make an open-world game with terrain and foliage tools
  • develop a multiplayer game with built-in networking
  • prototype games quickly with visual scripting
  • render realistic scenes with real-time global illumination
  • build large worlds with 64-bit coordinate precision

When to choose

  • you want a full-source, modern 3D engine with fast iteration and hot-reloading
  • you need C# and C++ scripting in the same engine
  • you target many platforms including consoles and web
  • you want real-time GI, GPU lightmaps, and VFX tools out of the box
  • you are an indie or small-to-large team wanting a lightweight, agile editor

When to avoid

  • you need a fully permissive open-source license (Flax uses a 4% royalty above $250k/quarter and restricts source redistribution)
  • you primarily make 2D games
  • you require NDA-protected platform support from source (excluded from the public repo)
  • your team is deeply invested in another engine's ecosystem or asset store
