A VPN exit node for about 30 cents a month
I like small, cheap, boring servers. Lately I have been trying hourly-billed VPS hosting, where server resources are billed by the hour.
My current one is a tiny Debian 13 box in Amsterdam that I use as a Tailscale exit node. It has 384 MB of RAM and costs me roughly 0.30 tokens a month on TierHive. I topped up 3 USD for 3 tokens, so one top-up goes a very long way.
It is a NAT-based host, so check the port situation before you plan anything that needs public UDP or DNS.
