Tor-friendly free shells for a small onion-service backup?

Hi! I’m into sovereign computing and Tor. I run a tiny static onion site (personal learning project, very low bandwidth) on a free shell box, and I’m looking for a second free (or very cheap) shell/pubnix provider that tolerates a small Tor hidden-service daemon (not a relay or exit) as a backup.

Which hosts are known to be Tor-friendly? Any to avoid? Thanks!

Are you running StartOS on this free shellbox? I’m curious as to where you found a free VPS, and what the specs, and conditions are?
