Infofractal is a server provider that seems established in 2019, which provides servers in Chile, for which I have no more information at present. But you can get test vps to run your own application their free ipv6 vps, if you want to get a shared ipv4 address (NAT VPS) you need to open a ticket.
Cloud VPS Free Tier 1c/512mib/8gib/500gib38 Available (Limited stock)
Previously, only some ports were opened, but now it may be changed to limit the network speed, as I remember.
It has to be said that the performance is... not good, but if you just want to try it or you can't pay for the server, you can try it.
