Ligess is basically Alby Hub for LND. It's both a Lightning address server, as well as a zap handler. So one can send zaps and receive zaps directly from LND, as well as receive payments to your lightning address on your own domain.

I haven't used Alby Hub, so not sure how they are similar/different to each other. As for my implementation, exposing the balance would be a security issue, as any app that is connected through NWC has access to that. 

 Alby hub has integrated ldk node with nice channel management features. It can also work with other ln implementations like lnd which is like adding a nwc interface.

I like the integrated ldk node, its very simple. But i want to remove the dependency of alby's relay 

 You can use any nostr relay. Nothing special about nwc 

 Alby hub generates nwc strings with relay.getalby.com/v1. I cant just change the relay in the string, right? Alby hub is listening to the relay it generates in the nwc string? 

 You can change the relay for your hub via environment variable:

You can't just change the connection string manually, since the hub needs to know which relay to listen to for incoming requests. 

 Gracias!
