Mix 16x16 and 32x48 tiles on one map.
GridCraft is a tile map editor for the browser and the desktop. It opens your Tiled .tmx, lets you edit it with your team while they watch the cursor move, and saves it back so Tiled can still read the file.
One atlas, more than one tile size
Drop 16x16 terrain, a 32x48 door and a 48x32 cart into the same sheet and paint all three onto the same map. Tiled cannot do this, and it is usually the reason someone tries GridCraft at all.

You see their cursor, their selection and their tiles landing as they paint. It syncs over CRDT, so two of you painting the same corner does not produce a broken file.

Save it back. Tiled still opens it.
No import step, no conversion, no separate GridCraft project file. You open the .tmx you already have, you edit it, and you save. Here is one after a round trip through GridCraft.
Two lines changed, because two things were added in the editor: a tileset whose tiles are 32x48, and a collision box.
.tmx<?xml version="1.0" encoding="UTF-8"?><map version="1.10" orientation="orthogonal" renderorder="right-down" width="64" height="40" tilewidth="16" tileheight="16"> <tileset firstgid="1" source="overworld.tsx"/> <tileset firstgid="513" source="props-32x48.tsx"/> <layer id="1" name="ground" width="64" height="40"> <data encoding="csv">17,17,18,42,42,... </layer> <objectgroup id="3" name="collision"> <object id="7" x="128" y="96" width="32" height="48"/> </objectgroup></map>The interface is familiar. Three things in it are not.
If you have used Tiled you already know where everything is, and that is on purpose. The three wide tiles below are the ones you cannot get anywhere else.

Open a .tmx or .tmj, edit it, save it. Tiled opens it afterwards. GridCraft keeps its own extras somewhere Tiled ignores rather than rewriting your file around them.

A packed, gzipped map plus a JSON companion, sized for a game server to read at startup. You do not write a parser or invent a wire format.

Brush, terrain, flood fill, shape, selections, stamps, and the object tools you already use in Tiled.

Connect GitHub or GitLab in the desktop app and commit, push and pull your map files without leaving it.

The same editor either way. The desktop build adds local file access, Git, the MCP server, and LAN hosting for collaborating without going through our servers.

The editor is free. You pay for the cloud, or for the desktop app.
These are two separate decisions, so they are two separate lists. Owning the desktop app is not a subscription tier and does not change the plan you are on.

Mac, Windows and Linux. Works with no connection at all. Adds local file access, Git, the MCP server for AI agents, and LAN hosting.
Buy it once and it stays yours. It is not a tier: you can own it on the free plan, and subscribing later does not replace it.

Open it and paint something.
The web editor needs no account. Make one if you want your maps saved to the cloud and synced to another machine, which takes about thirty seconds.
We ship updates most weeks and the product is not finished. If an export format or a tool you need is missing, tell us and we will build it.
