Ubuntu LTS, CLN lightning node, compiled libre relay from source. , my own lnurl implementation. A ton of other stuff obviously but that's the Bitcoin stuff. Oh I guess I run a docker for mempool instance and I also run a regtest node linked as "testnet 3" in my mempool instance. I have core also ready to go, so I can switch binaries for Bitcoin on the fly. I also have RTL for CLN. It's all just running as binaries for the most part. I think mempool is the only docker thing I have on my server. Same server runs my site and my nostr relay and blossom server. If I want to run something new, I get the software from source and run it. Make my own service files. I'm sure I'm missing something but this paints good picture.

Oh I run elements too. I haven't used it quite some time though.

I'm not knocking on albyhub users btw. Everyone has their own spectrum of diy. No shame in that. Alby has been a great custodian of the ecosystem. I did write an article on why not to run umbrel/start 9 and other os adjacent app stores in case you're interested in my thought process.
