Sprite Fusion

What it does

Sprite Fusion is a free, browser-based tilemap editor for designing 2D levels with any tileset. Import tiles by drag-and-drop or clipboard paste, draw with single or multi-tile selection, use auto-tiling and collisions, then export as a native Unity, Godot or Defold tilemap, or as JSON, TMX or PNG.

Sprite Fusion is a browser tilemap editor for building 2D levels from any tileset. You import tiles by drag-and-drop or clipboard paste, draw with single or multiple tile selections, and use auto-tiling for terrain. Layers can be marked as colliders for collisions. Exports include native Unity, Godot and Defold tilemaps, plus JSON, TMX and PNG files. The web edition is free, needs no login, and allows personal and commercial use with unlimited projects, but map export is limited to 4.5MB. A paid desktop edition adds offline use, faster exports and maps of any size. The props generator is available on the web only. The site lists an API and MCP in its navigation, but the homepage text does not describe what they do.
