Golly

Golly is a versatile, open-source Chrome extension designed for enthusiasts and researchers to explore Conway's Game of Life alongside numerous cellular automata types. It supports both bounded and unbounded universes and allows cells with up to 256 states, providing a rich environment for simulation.

The extension features multiple advanced algorithms, including Bill Gosper's efficient hashlife algorithm, and supports diverse automata such as John von Neumann's 29-state CA, Wolfram's 1D rules, WireWorld, Generations, Langton's Loops, and Paterson's Worms. Users can load various file formats like RLE, macrocell, Life 1.05/1.06, dblife, and MCell, plus extract patterns and rules from zip files and download resources from online archives. Additional features include an extensive, integrated Life Lexicon, unlimited undo/redo capabilities, and a comprehensive state-of-the-art pattern collection, making Golly an indispensable tool for cellular automata exploration.
