I’m not suggesting appimages are better, just that I’ve had fewer problems with them relative to snaps. Ultimately I’d argue all attempts to remove dependencies are not ready to replace typical packages for low powered systems. For desktop Linux the performance difference is negligible anyway.
+1 for VPS, the ionos ones are $2/mo and have unlimited bandwidth at 400mbps. That’s basically the cost of electricity for a home server with orders of magnitude better reliability.
