Verdant Autotile Playground is a free browser tool for a 47-mask autotile set, with importers for RPG Maker MZ, Tiled and Godot in its free tile pack. Paint dirt onto grass and watch a complete 47-mask blob autotile set decide, tile by tile, which of its 47 pieces belongs in each cell. Turn on Show mask numbers and the neighbourhood byte every cell computed is printed right on it.
Free, runs in the browser, nothing to install. Why this exists A screenshot cannot show you whether a tile set is complete, because the pieces missing from an incomplete set are exactly the ones a screenshot does not contain: the inner corners, the diagonal joins, the single isolated tile. So paint a hole in the middle of a solid area and look at the ring of values around it. That is the part that is usually broken.
