2D Tiler vs Hammer++

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.

Hammer++ is a free Windows modification of Valve’s Hammer editor for creating maps in the Source engine. It aims to improve stability and keep the editor current through fixes and changes. It can simulate Source lighting inside the editor, with adjustable quality and speed and dynamic updates, and preview particles, fog, skyboxes, rope physics, render effects, and material proxies. Mapping tools include a 3D gizmo, polygon and sprinkle tools, multiple cordons, brush merging, and object placement on floors or ceilings. If the editor crashes, it shows a detailed error message and autosaves open VMF files. Saved VMFs retain precise vertex data while also storing less precise data for compilers and compatibility with other Hammer versions. Downloads bundle HLMV++, which can be installed optionally. The download page lists build 8871, last updated April 14, 2026. The maker directs users to its official Discord for discussion and says the project is not affiliated with Valve. It also notes antivirus software sometimes flags downloads and advises allowing them or adding an exception. The old Source 2013 Multiplayer version is unsupported, and CS:GO support is frozen on build 8864.
