NSH was my go to for years for quick unimportant sites. Like a decade ago. They actually were very helpful the once or twice I contacted them (trying to get bigger instances). And $1 a month!
If your needs can live in ½GB RAM and a few GB of space, it is fairly easy to find $1/month VMs. Cheaper if you don't mind paying annually and/or can cope with ¼GB RAM or other lower specs.
Fine for simple static hosting, or a bit of low concurrency more-dynamic server-side stuff, or running simple services like DNS.
https://www.serverhunter.com/ lists a few, and many for not a lot more, if your resource needs are low enough. Cheapest currently listed is $9.5/yr if you need an IPv4 address. You'll also see them offered in places like lowendbox / lowendtalk / webhostingtalk / similar.
