@robi I've been using Servarica since 2020 and have no complaints. I have two of those older Polar Bear servers, and in fact a newer "Black Friday 2024 - UniFied - UniFied FAT" on which I'm running a BTCPayServer due to having 8GB of ram.
We now have a working LibreChat cloudron container set up. See: https://forum.cloudron.io/topic/12850/first-try-app-packaging-librechat-issue-with-postgresql-extention-pgvector/14?_=1749416165430
