or yunohost plus any other free vps, just look it up, idr where else has one, some places have credits if you signup with codes or off certain links like hetzner has free credits, vultr, and some others too, lowendtalk also has hella cheap vps under 10$ amonth that can support lemmy + more apps easily, the issue is space fills up fastish after a few months, and I think by default in the yunohost version theres a pictrs error that makes photo uploads crop weird you have to fix. (if you upload photos through it)
