Any self-hostable alternative to playit.gg for easily exposing local game servers to the public internet?

For those who don't know, playit.gg is a free/cheap service for exposing self-hosted local game servers to the wider internet.

But as someone who already has access to a cheapish VPS, I'm curious if anyone knows of any self-hostable alternatives that I could just run as a container on my VPS.

I've been toying with using Wireguard UDP tunneling, but it's proving to be a little bit more difficult and complicated than I was bargaining for. So if anyone knows of anything out there that does something like this, I'd be grateful!

Pangolin would work, it’s still wireguard underneath but with a webUI to set up things and simplify it. It’s fairly easy to install on your server with their docker compose examples.
