Does anubis need a reverse proxy?

[UnknownSuperficialNight]

For example, is it possible to expose Anubis publically then it internally redirects to a localhost or acts as a middle man itself?

example:
Internet -> Anubis -> Forgejo instance

No need for a reverse proxy, just a direct link, and Anubis will only let connections that pass to forgejo?

anubis can't serve TLS, so you would need a proxy such as stunnel for that, but a nginx/caddy/etc isn't required.
