GtkRadiant vs Remere's Map Editor

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.

Remere's Map Editor is a free map editor for OpenTibia, an open-source implementation of the MMORPG Tibia. It provides tools for creating and managing maps, including tile and entity placement, terrain flood fill, waypoint tools, and animation previews. Search tools can locate items and find unique IDs, action IDs, containers, and writable items in a selected area. Users can import and export zones and export a minimap for a selected area. Version 4.0 adds compatibility with the Canary and Assets Clients repositories, reads assets from client 11 or higher, and includes Lua scripting and a real-time monitor for FPS, CPU, and RAM. The project supports Windows, Linux, and macOS and provides compilation guidance for each; compiling requires wxWidgets 3.0 or later and Boost 1.55.0 or later. The project is licensed under GPLv2. Its README points to the official website for releases and provides a separate download link for version 3.X until it is added to that site. The free plan costs nothing; redistribution is allowed only in unmodified form.
