Sprite Fusion

Sprite Fusion is a free, web-based tilemap editor that lets game developers create 2D levels right in their browser. You can import any tileset through simple drag-and-drop or clipboard paste, then use an intuitive interface to design maps with single or multiple tile selections. The tool includes auto-tiling for efficient terrain creation and supports collision layers for game physics. It works natively with tilesets from PixelLab and provides smart fill tools for rapid level design.

What makes Sprite Fusion stand out is its direct export functionality to popular game engines. You can export your maps as native Unity packages, Godot scenes, or Defold assets with one click, eliminating the need for custom code. It also supports Virtual TableTop platforms like Foundry VTT and Roll20 with UVTT file exports. The web version is completely free with unlimited projects and no login required, while a one-time purchase desktop edition offers offline use and larger export capabilities.

Game developers working on 2D projects—especially platformers, RPGs, or mobile games—will find Sprite Fusion most useful. It's ideal for indie developers and students who need a simple, no-cost solution for level design. The tool is also valuable for tabletop gamers creating digital battle maps. Since it runs in any modern browser, you can start designing immediately without downloads or installations.
