Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

LDtk

  • No web, iOS, or Android build; it is an Electron desktop app for Windows/macOS/Linux only
  • Native format is JSON; use with other formats such as Tiled TMX requires a separate importer or custom parsing
  • Engine integration depends on separate official importers/libraries per engine (Unity, Godot, MonoGame, Bevy, GameMaker, Haxe, Playdate)
  • dev-x.y.z branches on GitHub are explicitly flagged as potentially unstable and not for production

PrusaSlicer

  • Limited to slicing workflow only; no interactive 3D design capabilities
  • Designed for RepRap-based printers; compatibility with other printer architectures varies
