FOSS gamedev and creative worlds

is there a way to host a minetest server with at least one mod? I know about MinetestHosing.com but you have to pay 45 dollars to install mods which I think is a ripoff. if anybody has a suggestions, let me know! i need at lease 5 slots, 1 mod or subgame. does not have to be 24/7. and I don't need much in terms of performance, as long as there is not to bad of a delay.

The easiest and fastest solution for this would be to use Selfhosting (©®™). Even with a few dollars it's possible to buy a Rasberry PI to run a Minetest server on it.
If your connection is not fast enough to handle some players, then you can either ask someone to host it for you (VPS not used entirely, as example) or rent a server.
The last small Minetest server I ran was on an old dual core laptop with 2 GB RAM and a quite slow connection. Everything below 15 players ran fine back then.
