4nt is free and stays free: no ads, no upsells, no account required. If it's earned a place on your machine, a tip helps me pour more hours into further improvements. Either way, thanks for being here.
Hosting, the domain, engine tooling, optimization, and the hours that go into building out this sim's full list of features. That's it. 4nt stays free for everyone, tip or not.
