When our open source grant from NLNet runs out at the end of this year, we will have to switch to full community funding, probably via yearly funding drives. Currently we only have two full-time devs, @nutomic@lemmy.ml and I, but could potentially add more to our little worker coop as we grow.
If you'd like to help us out, here's our donation page: https://join-lemmy.org/donate
Liberapay is much preferred, but the other ones work too. I'm sincerely grateful to everyone who has or is contributed, it really does make us feel like we're working on something worthwhile.
Liberapay is simpler, automatically splits payment between devs, and has no fees (other than the payment processor). Theyโre even funded by their own model.
Opencollective isnโt as good because you have to submit invoices to get paid.
Patreon is absolutely the worst because itโs not made for teams, and they take a big cut for essentially just running a wordpress for you with payment buttons.
