A Tile Map Editor that runs in your browser
Mix tile sizes in one map: drop 16x16 and 32x48 side by side. Edit it live with your team, in the browser or the desktop app, which almost no tile editor lets you do. GridCraft reads and writes Tiled's .tmx and .tmj, and exports to Godot, GameMaker, Defold, and more in one click.

Tileset
Live demo. Click or drag to paint, and drop the larger tiles to mix sizes on one map, like the real editor.
// Capabilities
Built for game developers
The interface will feel familiar from the first click, so there's nothing to relearn. Underneath, every tool has been rebuilt to be faster and less fiddly, and a few of them do things you won't find anywhere else.
Exclusive
Variable-sized tiles
One atlas, multiple tile sizes. Drop 16x16, 32x48, and 48x32 into the same sheet and paint them onto a single map.
Rare
Real-time collaboration
Edit the same map at the same time, something almost no tile editor lets you do. Cursors, selections, and tile paints sync live over CRDT.
03
Binary export for servers
One click gives you a packed, gzipped binary plus a JSON companion, made for a game server to read at startup. You don't write a parser or design a wire format, we already pack the map as tightly as it goes.
04
Export to popular engines
Export to Godot 4, GameMaker, Defold, LDtk, LOVE2D, and CSV, one click per format. Need a target we don't have yet? Ask, and we'll build it.
05
Tiled compatible
Already on Tiled? Drop your .tmx or .tmj in, edit, and save it back, with no conversion step. Your maps and your workflow come along as they are; GridCraft-only fields stay tucked away so Tiled can still open the file.
06
19+ tools
Brush, terrain, flood fill, shape, selections, stamps, and every Tiled object tool.
07
Git built-in (desktop)
In the desktop app, connect GitHub or GitLab and commit, push, and pull map files without leaving the editor.
New
MCP server
The desktop app runs a Model Context Protocol server, so AI agents like Claude can open your map and edit it directly: paint tiles, fill regions, add layers, and place objects. Every change goes through the normal undo history.
09
Web + desktop
Run GridCraft in the browser or as a native Electron app for Mac, Windows, and Linux. The desktop build adds Git, the MCP server, LAN hosting, and local file access.
