I run a language learning app* on a single VPS, for free. I'm not sure if you can still get it, but Oracle used to offer very generous VPS for free. I have a 4 CPUs, 24 GB memory VPS that I'm using for several things, including running the backend and the marketing site for that app.

I installed Plex but ended up not using it, so I removed it.

Mail / IMAP server for my family domain. Small web server with a few static content sites. Trillium notes server.

Pretty low maintenance overall - I can go months without even thinking about it.

I'm fairly certain that DHH fella is Nazi adjacent.

If you don't have a use maybe you do not have a use?
