Always searching for other interesting and useful things to selfhost 😅
For Matrix I'm currently using the Element client, what is your experience with Cinny? Would you recommend it?
Cinny supports custom emoji reactions and stickers, enough said :P
More seriously, yes. It looks very good, has the right amount of settings, and it's pretty intuitive. It doesn't do the silly thing Element does for stickers where you need to selfhost a webpage (for which I shall forever be salty about), you can just join a stickers room and enable stickers globally or just add stickers manually.
at home I just have a jellyfin running on a repurposed gaming pc, which I plan to put a caddy on eventually some day hopefully
otherwise online (which admittedly is a little less self-hosted) I've got a server with FoundryVTT on it, and one with me blog (full Django with automated gunicorn and all; I got the thing coded, deployed, and running as professionally as possible to see how much I could do by myself. took me two months but worth it)
cage (kiosk wayland compositor) with kitty and btop for a nice stat display on the device
All of it running from a phone with Linux :3
I used to have Nextcloud on this thing, but I found it to be insanely heavy for what it does and not very useful when I can just chuck files to the web server if I want to share them.
When I was hosting game servers (mostly modded Minecraft) I'd always self-host them. I've never been a fan of using hosting services for these as from my experience they tend to perform poorly by comparison.
