Phoenixd is a Lightning node (https://phoenix.acinq.co/server/) that works a lot like thir app, uses ACINQ as the LSP so you never have to worry about liquidity or finding people to open channels with, they handle all of that for you, for a fee. So, you just need to run phoenixd to have self-hosted lightning, and phoenixd-lnurl alongside it to have self-hosted LNURL and Zaps. Currently does kinda require that you've already got a server running somewhere, more work needed to get this to work on node-in-a-box solutions like Umbrel, Start9 etc.

Ok thanks for the explanation, not quite sure it's what I was expecting. I already run an Umbrel with Lnbits and lnurlp with Lightning address. And yes it's quite complicate to setup and in my case it's quite unrelable, not sure why exactly. Still hoping for an easier and more reliable solution that is still self-hosted and non-custodial.

Made it all run in portainer on umbrel... sats@zap.alex71btc.com/lnurl
