Sprite Fusion

Overview

Sprite Fusion keeps its workflow focused on tile-based maps: import a tileset by dragging it in, loading an image, or pasting from the clipboard, then draw with pencil, fill, selection, and attributes tools. That mix covers the core work of assembling a level without requiring a desktop app, making the web edition appealing for smaller projects and browser-first workflows.

Autotile layers select tiles according to neighboring cells, with variants, weights, and reusable rule presets. This can reduce repetitive placement while preserving some control over how edges and transitions resolve. Collision layers travel with supported exports, and UVTT output can turn collider layers into wall boundaries for virtual tabletop software such as Foundry VTT.

Key features

• Tileset-based map editing: Import image tilesets and use pencil, fill, selection, and attributes tools. The focused toolset suits tilemap construction, rather than broader level-design workflows.
• Autotiling: Neighbor-aware rules, variants, weights, and reusable presets help automate tile selection for connected terrain.
• Collision data: Mark layers for collisions and export them to Unity, Godot 4, Defold, and Bevy. This is useful when the destination engine supports one of those collision targets.
• Multiple export paths: Engine targets include Unity, Godot 3 and 4, Defold, Bevy, Love2D, GDevelop, Phaser, Cocos, and GB Studio. Maps can also be exported as TMX, Sprite Fusion JSON, PNG, or UVTT, so the editor serves both game projects and tabletop map workflows.
• Virtual tabletop output: UVTT exports support VTT software such as Foundry VTT, with collider layers converted to wall boundaries.

Pricing

Web Edition — 0.00 USD per free. It includes personal and commercial use, unlimited projects, and no login requirement. The trade-off is a 4.5MB map export limit on the free plan; browser exports also have a 5MB size limit. That makes the web edition a sensible choice for small maps, but a constraint for larger projects.

Desktop Edition — 14.99 USD per once, billed One-time purchase. The Windows and macOS app works offline, exports maps faster, supports maps of any size, and includes free lifetime updates. Choose it when the web export ceiling is too restrictive or offline access matters. Props generator is available on web only, so buying desktop does not move that capability into the app. No free trial is offered.

Platforms

The editor is available on the web and as desktop software for Windows and macOS. A 64-bit Linux desktop build is experimental; Linux users should treat the web version as the more established option. Desktop access adds offline work and faster exports, while the browser edition avoids an installation and account requirement.

Who it's for

Sprite Fusion suits 2D game developers building tile-based levels, including retro projects such as Game Boy games. Its engine export range makes it relevant to developers using supported targets, while UVTT output also serves virtual tabletop map makers. The maker also positions it for educational apps. Users needing help are directed to the Sprite Fusion Discord server.

Pros and cons

Pros

• Several ways to bring in tilesets: Drag-and-drop, image loading, and clipboard paste accommodate different asset workflows.
• Useful rule-based terrain tools: Autotiling with variants, weights, and reusable presets can cut down repeated tile selection.
• Exports cover many destinations: Engine-specific formats, common map and image formats, and UVTT output make the editor useful beyond one engine.
• Desktop purchase removes the map-size ceiling: The one-time payment includes offline work, faster exports, maps of any size, and lifetime updates.

Cons

• The free web export is capped: The homepage sets the free-plan limit at 4.5MB, while the browser version has a 5MB export size limit; larger maps point toward the paid desktop edition.
• Linux desktop support is experimental: Linux users cannot rely on a stable standalone build on the same footing as Windows and macOS users.
• Props generator is web-only: It remains a browser capability rather than part of the desktop feature set.

Verdict

Choose Sprite Fusion if you want a browser-accessible tilemap workflow with autotiling and exports spanning game engines and virtual tabletops. The free web plan is well suited to smaller maps; its limited export size is the main reason to pay 14.99 USD once for the desktop edition. Look elsewhere if you need a stable Linux desktop app or want the props generator in your installed software.
