Support Waifly
Waifly gives away free servers, and free servers still cost something: two machines in Paris, their electricity, their bandwidth and their backups. Donations pay for that.
There is nothing to gain from donating — no priority support, no extra resources, no badge. The free plan stays exactly as generous for people who give nothing. That is rather the point.
Payments are handled by Ko-fi; Waifly never sees your card details. One-off or monthly, both help. If you would rather not give money, telling someone about Waifly helps too.
