Maybe you can try The Lounge? It is somewhat different than an IRC proxy since it has a web client (that is always connected)

I recently started using Fedora 39 KDE Spin as my main driver. It mostly just works out of the box. You'll need to add some repos to get media support etc. but that is just a quick Google-search away.
I have been using Debian for a long time for my home server and to be honest, and it never once failed me. In my experience, Debian on a server is just rock solid. When I made the switch from Win11 (I don't like a snooping AI in Notepad) to Debian (stable) I wasn't that happy. Apps were outdated, Wayland was f**king things up, etc. So I switched to Debian testing (trixie) and installed KDE the manual way. That way I hoped to get a really 'clean' system, leaving some of the standard apps (that I wouldn't be using anyway) behind. Although Debian testing seemed really stable, the 'manual way' left me with some quirks that left me unhappy. For a reason I can't remember, I decided to try out Fedora 39. And I have to say, it has been great. Up to date apps, no unexpected errors or crashes, etc.
Looks nice, but Orb already exists. Which is FOSS. You might have problems competing if you decide to go closed source...
It's focus may be rdp, but it supports SSH connections just fine. I switched my main driver yesterday from Windows to Debian (Cinnamon). I came out looking for the same thing as OP, Remina fitted right in as an SSH connections manager
I have had issues since yesterday. Seems like I'm getting SERVFAIL responses and some of their nameservers seems to lose connection
For dutch content on Usenet, I can strongly recommend Spotnet. If you are familiar with docker, you will find a turnkey solution here to get you going with spotnet.
Short explanation (from Wikipedia): "Spotnet is a protocol on top of Usenet, providing a decentralized alternative to usenet indexing websites, and the NZB format in general. Spotnet allows users to create and browse private 'newsservers', or decentralized repositories of files and information. Members share spots (file sharing) with one another, similar to the seeding process in torrent sharing".
