If you can live on ipv6 only fly.IO is free for 1 CPT shared with low RAM and disk. Up to 3 are free. An ipv4 ip is $2 per month.
Oracle is supposed to be the better deal but refuses to accept my credit card and I’ve heard lots of issues like erasing servers.
At $2-3 IONOS is the next step up. Digital Ocean is popular too but at$5 blows up your budget.
May want to look for stable storage first.
