LDtk vs Remere's Map Editor

LDtk is a free, open-source 2D level editor for game developers, available for Linux, macOS, and Windows. It supports Grid-vania, linear, and free-world layouts, with levels rearranged by drag and drop. Its visual auto-layering editor lets users define rules for tile skinning, while custom entities can hold typed properties such as hit points, patrol paths, or inventories. LDtk exports PNGs and JSON entity data, with optional Tiled TMX export. It can load Aseprite files directly and reload them when saved. The editor focuses on platformer and top-down perspectives, rather than isometric 3D. Backups can restore unsaved changes after an application crash. The maker lists community importers and loaders for engines including Unity, MonoGame, Godot, Playdate, GameMaker Studio, Löve 2D, and Bevy. LDtk has no usage limitations stated, and content created with it may be used commercially. Documentation and an official Discord community are linked from its site.

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.
