Hi Product Hunt 👋 I'm Ferenc, the maker of Cellula. Conway's Game of Life is one of those things that hooks people the first time they see it: four simple rules, and suddenly gliders, oscillators and things you didn't expect. But most online versions are a demo on a single page: no way to save what you made, no way to send it to a friend, and you're stuck with the one rule set. Cellula is my attempt at the version I wanted: An unlimited map — click cells to life, pan and zoom, step forwards and back through generations Your own rules per world — pick which neighbour counts cause birth and survival, and explore automata beyond Life Save into projects and reopen your worlds on any device Share with a link — anyone can watch your world run, no account needed Make it yours — colours, zoom, speed, light/dark, five languages, and a cell pattern as your avatar It's free, runs in the browser, nothing to install. I'd love to hear: What pattern or rule set should I try? Share your world link here. What's missing for how you'd use it (teaching, art, just tinkering)? Bug reports and feature requests are very welcome on the public issue tracker — link is in the app footer. Thanks for taking a look!
