Sprite Fusion is a browser-based toolkit for 2D game art and level design. The free Tilemap Editor lets you import any tileset, paint maps with auto-tiling and collision layers, and export directly to Unity, Godot, Defold, and other engines. The AI Pixel Art Generator turns text prompts into 16x16 to 64x64 sprites, then animates them, adds 8-direction views, and matches styles. It suits indie developers, game jam teams, and tabletop creators.

• Browser-Based Tilemap Editor: Drag and drop or paste any tileset and start painting maps right away. The Web Edition is free, needs no login, and covers personal and commercial use with unlimited projects.
• Auto-Tiling and Smart Fill: Rule-based auto-tiling places matching terrain edges for you, and Smart fill covers large areas fast. You spend less time placing border tiles one at a time.
• Layers and Collisions: You can set any layer as a collider, and add custom tile attributes. Collision data comes along when you export to supported engines.
• One-Click Engine Exports: Export native Unity packages, Godot scenes, or Defold assets with no custom code. JSON, TMX, and PNG exports cover Bevy, Phaser, GDevelop, Love2D, Cocos, Flame, GB Studio, and more.
• AI Pixel Art Generator: Generate game-ready sprites at 16x16, 32x32, or 64x64 from text prompts, with transparent backgrounds. A built-in editor lets you retouch results or draw by hand.
• Animation, 8 Directions, and Style Matching: Create idle, run, walk, and attack animations, including from your own imported sprites. Generate all 8 facing directions, or new sprites in the style of a reference sprite, so a character set stays consistent.
• Free Normal Maps and Pixel Snapper: Generate normal maps for sprites and animations at no credit cost. The open source Pixel Snapper cleans blurry or off-grid pixel art into a clean grid, with batch processing.
• API, MCP, and Engine Plugins: A REST API and MCP server let coding agents such as Claude Code or Codex generate sprites. Native Unity and Godot plugins bring the generator into your engine.

• Free Core Editor With No Sign-Up: You can open the Tilemap Editor and build maps for commercial projects without creating an account or paying.
• Fast Path From Map To Engine: Native Unity, Godot, and Defold exports mean you skip writing import scripts. Reviewers such as GameFromScratch point to direct engine export as its main strength.
• Wide Engine Coverage: Support spans Unity, Godot 3 and 4, Bevy, Phaser, GDevelop, Love2D, Cocos, Flame, Defold, and GB Studio, plus tabletop UVTT export.
• Low Learning Curve: Drag-and-drop tileset import and built-in auto-tiling let beginners and game jam teams get a playable map quickly.
• Art And Levels In One Place: You can generate sprites, animate them, and build the level using the same toolkit, which cuts down on switching between apps.
• Affordable Offline Option: The Desktop Collector Edition is a one-time purchase with lifetime updates, so you avoid another subscription for offline map work.

• Size Cap On Free Map Exports: The Web Edition limits map exports to 4.5MB. You need the paid Desktop Edition to export larger maps.
• AI Generator Requires A Subscription: The Pixel Art Generator runs on monthly credit plans from $9 to $49, and the pricing page lists no free tier. Included credits reset monthly and do not roll over, so usage that varies from month to month can cost you.
• Some Features Stay On The Web: The props generator and AI tools run in the browser, so the offline Desktop Edition covers map editing but not AI generation.

• Indie Game Level Design: You import a purchased tileset, paint terrain with auto-tiling, and mark walls as a collider layer. One click later, you have a Godot scene or Unity package ready to play test.
• Game Jam Prototyping: Under a 48-hour deadline, your team generates placeholder characters with the AI generator and builds levels in the browser. No installs or account setup slow anyone down.
• Character Sprite Sets: You generate a hero sprite, create all 8 facing directions, and add walk and attack animations. Style matching keeps enemies and NPCs looking like they belong in the same game.
• Retro and GB Studio Projects: GB Studio mode and export help you build maps that fit Game Boy-style constraints. You stay within the format without manual conversion.
• Virtual Tabletop Maps: Game masters design battle maps from tilesets and export to UVTT. Collider layers become walls for virtual tabletop platforms.
• Agent-Driven Asset Pipelines: Developers connect Claude Code or Codex to the API or MCP server so the agent can generate and animate sprites while it builds the game.
