Instead of GridCraft
GridCraft alternatives
GridCraft is built for 2D game maps, combining browser and desktop editing with mixed-size tiles from one atlas. Brush, terrain, flood-fill, shape, selection, stamp, and object tools cover core map work, while live cursors, selections, edits, and CRDT synchronization support small teams. It opens and saves Tiled files, exports to engines and formats such as Godot 4, GameMaker, Defold, LDtk, LOVE2D, Lua, and CSV, and connects desktop projects with GitHub or GitLab. The web editor has a free plan, while cloud and desktop plans add capacity, syncing, offline work, Git, LAN hosting, and MCP access.

You may prefer another editor for 3D level building, a specific game ecosystem, an in-game map workflow, or specialized asset and entity tools. GridCraft’s free account limits cloud maps, storage, devices, and collaborators; its desktop app is separately priced, and MCP does not edit infinite chunked maps. Compare each option’s game support, map dimension, export formats, collaboration model, operating systems, and whether its free offering fits your project size.
