LDtk vs Mapster32

LDtk is a free, open-source 2D level editor for game developers, available for Linux, macOS, and Windows. It supports Grid-vania, linear, and free-world layouts, with levels rearranged by drag and drop. Its visual auto-layering editor lets users define rules for tile skinning, while custom entities can hold typed properties such as hit points, patrol paths, or inventories. LDtk exports PNGs and JSON entity data, with optional Tiled TMX export. It can load Aseprite files directly and reload them when saved. The editor focuses on platformer and top-down perspectives, rather than isometric 3D. Backups can restore unsaved changes after an application crash. The maker lists community importers and loaders for engines including Unity, MonoGame, Godot, Playdate, GameMaker Studio, Löve 2D, and Bevy. LDtk has no usage limitations stated, and content created with it may be used commercially. Documentation and an official Discord community are linked from its site.

Mapster32 is a free map editor for creating Duke Nukem 3D maps in.MAP files. It is part of the EDuke32 project and is included with EDuke32. The editor is described as an advanced upgrade of the original BUILD Editor. Its 2D mode handles map layout and object placement; 3D mode edits textures, heights and shading. Mapster32 can also create levels for NAM, WWII GI, Redneck Rampage and other games. It supports scripts in a language derived from CON, loaded as.m32 files or entered through the editor console. The tool checks loaded maps for corruption and can attempt repairs in some cases. Serious corruption may still require manual expert resolution. EDuke32 lists Windows, Linux and macOS support. The Mapster32 plan is listed at free. There is no free trial because the product is provided as a free plan.
