When comparing Tiled vs GrafX2, the Slant community recommends GrafX2 for most people. In the question“What are the best 2D animation tools for game development?” GrafX2 is ranked 2nd while Tiled is ranked 7th. The most important reason people chose GrafX2 is:
GrafX2 is scriptable using the Lua language, which can be used to automate tasks and add new functionality to it. The script library features advanced color reduction and enhancement tools, [palette analysis](http://eab.abime.net/showthread.php?t=76519), and much more.
Ranked in these QuestionsQuestion Ranking
Not everyone uses the same operating system and why should they? Tiled supports Windows, Mac, and Linux so you can work in any environment you like. Also with daily builds you get to stay ahead of the curve!
Pro Free and Opensource
Using the GPL license means you get to use this software free and are free to make changes to it as you see fit.
Pro Unlimited Layers
Sometimes you need 20 layers to make something epic. Tiled lets you create as many layers as you need.
Pro Use Shell Commands
Setup shell commands within Tiled so you can setup workflows for each of your games.
Pro Supports Orthographic and Isometric tiles
Whether you want a straight on look at your world or a slightly skewed one Tiled has you covered.
Setup boarders with your tilesets so making tiles provide the correct connections automatically. This feature will speed up your level creation.
One of the coolest things is to create rules so you can automate the mapping process. Want to have certain tiles to always have a collider? Simply make a rule for it and it'll do it automatically. Speed up your mapping process with this feature.
Pro Many engines already have support
A big list of engines already have support for Tiled provided by those in the community. See if the engine you use is already on the list.
Pro Can create colliders and triggers within editor
Tiled makes it easy to setup triggers and colliders with its vector tools or you can set up a tile that’s invisible in your game. Change collider/trigger properties so you can access them within your game.
Pro Tile size and image size do not have to match
Want to import a giant object but don’t want to split it up? Import it and place it the exact size you want it as one object.
Create properties for your map, layers, tilesets, tiles, and objects. Have the flexibility you need to create the best levels for your game.
Pro Engine Agnostic
Tiled provides an easy solution for tile maps for any engine even the custom engine you are now making. This makes Tiled a very versatile tool for 2D games.
Pro Scriptable using Lua
GrafX2 is scriptable using the Lua language, which can be used to automate tasks and add new functionality to it. The script library features advanced color reduction and enhancement tools, palette analysis, and much more.
Pro Supports many file formats
GrafX2 supports many file formats, including the popular gif and png, but also importing and exporting from deluxe paint, degas elite, and various other editors using custom formats.
Pro Very large number of tools and effects
Pro Free, open source, and cross-platform
GrafX2 is totally free to use, copy, and modify. It's available on Windows, Linux, Mac OS X, Haiku, AROS, MorphOS, SkyOS, Syllable, Mint, and a few more systems. Basically anything is supported by the SDL library.
Pro Palette color cycling
GraphX2 being based on older 256 bitmap software has inherited some tricks that modern pixel editors do not have . One of them being the ability to cycle color palette and produce animations and effects with it.
Pro Has a great palette tool
You can create gradients from one color to another, work in either RGB or HSL color space, save and load palettes, sort and organize palettes, and even work on "color cycling" images.
Pro Supports tileset addition and extraction
Pro Supports animations
The program has a basic support for animation using frames in newer versions. Graphics can be cloned and copied between frames and changed slightly.

Pro Has a customizable UI with themes support
Theme UI style can easily be changed from settings including buttons and colors.
Pro Drawing constraint mode for vintage 8bits machine
The program is able to enforce the pixel constraints of old machines (C64, ZX Spectrum, Apple II, Game Boy Color, etc.)
For example, in ZX Spectrum mode, only 2 different colors can be used in a 8x8 pixel block.
Con Must implement .tmx if your engine doesn’t support Tiled.
It’s not a huge deal but you do need to implement Tiled into your engine if you don’t have it. Dont be lazy just follow this guideline (https://github.com/bjorn/tiled/wiki/TMX-Map-Format) to get your game running.Must implement .tmx if your engine doesn’t support Tiled.
Con Dated look and feel
It looks like it was never supposed to be used in the modern world.
Con Lack of modern features
Some modern features that are necessary to do pixel art creation for game dev work are lacking.
