It's a bit unclear for me how they can provide all the development and maintain the servers running. Are the donations enough?

They're spending ~$34k/month according to the cost breakdown sheet from https://lichess.org/patron, which is about 6,800 $5/month patrons.

They must also have a lot of $10 or more/month patrons.
