Is there a way to view the frontpage of another server, or get an RSS feed of another server's single community?

My lemmy account is on the programming.dev instance but I use newsboat for RSS reading of some lemmy.ml communities, along with browsing the local homepage of lemmy.ml and some other instances in a regular browser. Is there a way to do either of these things from the programming.dev instance so that I can easily comment on posts without having to manually locate the same post by browsing to /c/foo@lemmy.ml on my own instance?
