GridCraft vs GtkRadiant

GridCraft is a tile map editor for game developers, available in a browser and as a desktop app. It lets users paint tiles of different sizes from one atlas onto a map. Editing tools include brush, terrain, flood fill, shape, selection, stamp and object tools. GridCraft opens and saves Tiled.tmx and.tmj maps, with export targets including Godot 4, GameMaker, Defold, LDtk, LOVE2D, Lua and CSV. Live collaboration displays teammates’ cursors, selections and edits, synchronized through CRDT. The desktop app supports GitHub and GitLab for map-file commits, pushes and pulls. It can expose an open map to MCP clients for AI-agent access, but the server is off by default, binds to the local machine and does not yet edit infinite chunked maps. The free web editor includes all 19 tools and export formats without an account. Free accounts include three cloud maps, 25 MB total storage, one bound desktop device and collaboration for up to three people per map. Paid options include Cloud at $3.99 a month, Team at $13.99 a month and the desktop app at $19.99, paid once.

GtkRadiant is a free, open-source level editor and toolchain for games powered by id Tech engines. It includes map compilers, data authoring tools, and Q3Map2, with tools for 3D levels, terrain, and entity placement. The GtkRadiant 1.6 page lists support for games including Quake III Arena, QuakeLive, Urban Terror, Wolfenstein: Enemy Territory, Quake2, Quake2: Remastered, Quetoo, Return to Castle Wolfenstein, Star Trek Voyager: Elite Force, and Jedi Academy. Support for a game can depend on an active developer to test and address issues; some titles may require an older version or third-party fork. GtkRadiant reads and writes assets in a game's directory, and the project recommends installing the game first. It runs on Linux, macOS, and Windows. Linux distribution is through Flathub as a Flatpak; the Mac version requires XQuartz, MacPorts, and other dependencies. Volunteers maintain the GPL-licensed project, which is provided as-is without warranty or support. Listed help options include forums, IRC, tutorial sites, and a GitHub issue tracker.
