Will look into a docker container to install it on Umbrel
Today I am releasing "noflux", a lightweight RSS and Nostr longform reader for the desktop and personal servers: https://github.com/fiatjaf/noflux
It supports all sorts of RSS feed discovery from HTTP URLs and renders them beautifully in a simple straightforward interface, you can also paste nostr:... URIs, including nip05, npub and nprofile codes (they should also work without the nostr: prefix).

Something like this? https://hub.docker.com/repository/docker/fiatjaf/noflux
Thank you Legend, I'll try to send it to the guys @Umbrel
