Thanks for asking guise! It's cheap, Lemmy is written to be very resource efficient! Domain is USD10/y, hosting is about USD20/month.
And hosting is actually overprovisioned and could probably be USD5-10/month. I got a slightly bigger VM just in case (2 CPUs, 2GB RAM). But I'm seeing CPU % at 2.5% with just one spike to 10% in the last day. RAM holding steady at 52%.
Zero issues covering costs for this experimental stage btw! We don't know how this will go yet. And things have been good career wise lately. But yeah if we start seeing real traffic and need to pay for big boy servers, we may need to figure out something with the community!
In the future can consider Liberapay to crowdfund from monyets here for big boi servers because the platform accepts MYR (no need to convert currency and deal with FTF) and you can contribute as low as RM 0.05 per week. It also does not take any service fees because its run by donations too.
