IFStile is a cross-platform (Windows, Mac, Linux, Android, WebAssembly) freeware program that can:

build any affine directed graph iterated function system (IFS) in an Euclidean space of arbitrary dimension (as 2D or 3D section)
fully automatically find interesting fractal shapes, rep-tiles, multi-tiles, irreptiles, carpets, dragons, etc
extract the boundary of self-affine tiles as directed graph IFS
compute dimensions of the boundary of self-affine tiles (numerically and analytically)
export Apophysis .flame format
effectively zoom IFS fractals
render high resolution images (with batch rendering)
render keyframe animation
create and save 3D mesh

The program uses a special rendering algorithm that can unveil complex structures of the fractal.

When you save a rendered image to PNG format, the program automatically saves all parameters (IFS, palette) inside the PNG, and you can load such PNG to the program to restore your workspace.
