LDtk vs Sprite Fusion

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.

Sprite Fusion is a tilemap editor for designing 2D game maps, available in a browser and as a desktop app. You can import tilesets by dragging and dropping, loading an image, or pasting one from the clipboard, then draw with pencil, fill, selection, and attributes tools. Autotile layers use neighboring cells to resolve tiles, with variants, weights, and reusable rule presets. Collision layers can be exported for supported targets. Game engine exports include Unity, Godot 3 and 4, Defold, Bevy, Love2D, GDevelop, Phaser, Cocos, and GB Studio; other formats include TMX, Sprite Fusion JSON, PNG, and UVTT. UVTT exports can represent collider layers as walls for virtual tabletop software such as Foundry VTT. The Web Edition costs nothing and limits map exports to 4.5MB. The Desktop Edition costs $14.99, paid once, works offline, and exports maps of any size. It has Windows and macOS builds, plus an experimental 64-bit Linux build.
