Tilesetter is a cross platform (Windows, Linux and Mac) tool for generating tiles and tile based maps that can easily be exported to game engines including Unity, Godot, Defold and GameMaker 2. The biggest power of Tilesetter is it makes it incredibly easy to create auto-tile tilesets such as Wang tiles. Tilesetter is available on Steam and Itch.io for $13USD.
After a year in development, the Beta 2.0 version of Tilesetter is now available. Release note details are available here, key new features include support for layers when creating tile maps, support for “mixed-border” tilesets and additional game engine export options including Defold and JSON formats.
