Support Manifold
Manifold is free to use and stays that way. A donation buys nothing and unlocks nothing — the program is the same either way. It pays for the parts of it that cannot be written: the developer account that signs the Mac build, the machines the releases are made on, and the hours.
Once, any amount
The card details are handled by Stripe on their own page. Nothing about you or anything you have written is sent — the amount is all this knows.
Or on Ko-fi
Ko-fi takes no platform fee and no account is needed, which also makes it the way through if a card or a country gives Stripe trouble. Open Ko-fi →
What stays free
All of it. Every feature described on this site works without an account, without a network and without paying anybody — that is the design and not an introductory offer. What a paid plan will one day add is somewhere to keep a second copy and things that cost money to run; it will never be the editor.
