Yes. Every rule, palette, surface, and simulation feature is free with no account required, and free exports include a signed 1920×1080 PNG. Cellscape Pro is an optional one-time unlock for print-resolution export, transparent PNGs, video, and watermark removal — the core tool never requires it.

Cellscape Pro is a one-time purchase via Gumroad that unlocks print-quality export (up to 7200×10800 at 300dpi), transparent PNGs for garments, video export, and the ability to remove the signature watermark. Click "Unlock Pro" in the Export card, buy the license, then paste the license key from your receipt to activate it in your browser.

No. There's no sign-up, login, or account of any kind for the free tier. Cellscape Pro only requires a license key from your Gumroad purchase, pasted once into the unlock dialog.

Free exports are 1920×1080. Cellscape Pro adds 4K (3840×2160), a 3600×3600 square print size, a 4500×5400 t-shirt DTG size, and poster sizes up to 7200×10800 at 300dpi — enough for large-format printing.

Cellscape doesn't restrict what you do with art you generate and export yourself — the tool is free to use for personal or commercial output. If you plan to sell physical prints at scale, make sure the resolution you export (available via Cellscape Pro) matches your printer's requirements.

Conway's Game of Life (rule B3/S23) is the best-known and most-studied cellular automaton, and the most approachable starting point for understanding how the birth/survival rule system works before exploring the 30+ other rule presets available.

The page itself needs to load once over the internet (it's hosted, not downloadable), but the simulation, rendering, and export all run entirely in your browser afterward — no server round-trip is needed to play, paint, or export.

Any modern browser with WebGL2 support — current versions of Chrome, Edge, Firefox, and Safari all work, on both desktop and mobile. Older browsers without WebGL2 fall back to a slower Canvas 2D renderer automatically.
