2D Tiler vs Dune II - The Maker Map Editor

2D Tiler is a free, open-source web editor for 2D game levels, tilesets, pixel assets, palettes, and exports. Its layered map tools include painting, erasing, filling, selection, autotiling, and object placement. Terrain options cover standard, diagonal, sparse, and 16-slot Wang workflows, plus weighted fills. A built-in image editor offers drawing, selection, cropping, moving, and blur tools, among others. Palette imports include GIMP GPL, Adobe ASE, Aseprite, JASC PAL, Paint.NET TXT, and HEX lists.

An AI workspace can create tilesets, sprites, backgrounds, icons, UI elements, and visual effects using OpenAI, Google Gemini, xAI, and Together AI provider families. Provider choice determines availability, billing, content rules, and image privacy. The editor runs locally in the browser and stores project data through a browser-based workflow. Native formats are .2dp projects, .2dm maps, and .2dt tilesets. Map workflows support Tiled, Godot 4, Unity, GameMaker, Defold, Phaser, tIDE, and Mappy formats; raster support includes PNG, JPG, WebP, BMP, and GIF where the selected path allows it. Tiled map and tileset files are supported, but Tiled project-container import and export is planned, not available.

Dune II – The Maker Map Editor is an in-game tool for creating and editing skirmish maps in the open-source Dune II remake. Players can build maps without leaving the game and then play them immediately. Editing tools include terrain painting, spice placement, player starting positions, zoom, pan and symmetry. Grid and axis overlays help with placement, while undo, redo, copy and paste support revisions. Edited maps are saved in the skirmish folder and appear in the skirmish map selection screen. The editor is described as an initial version focused on essential playable skirmish maps, with plans to expand it for campaign maps. Version 0.8.5 also includes minimap move orders, camera tracking for selected units, configurable key bindings, improved pathfinding and a random-game option for skirmishes. It is free and open source, with Linux, macOS and Windows listed. The release page offers a stable download as d2tm.zip and source code. Feedback and issue reports can go through Discord, forums or GitHub tickets.
