If the project has a lightning address (and it likely does if theyre on nostr) then you can set up nwc to pay regularly using zapplanner. I do this for opensats@vlt.ge using alby hub
I like using lightning self custodially and alby hub is probably ideal for me. I wish the wallet interface in Alby Hub was more like Alby Web (https://getalby.com/dashboard) so thered be less need for a connected Alby account
Send appears to accept bolt11 invoice only. If it accepts lightning address or lnurl then the text could be more clear. Send in Alby Web has a camera option, Hub does not.
In web, receive displays a QR and create invoice option. Would be nice if hub did the same. And if the user doesnt have an alby account then a bolt12 qr could be displayed instead.
zapplepay worked for that, but then it stopped working mysteriously. i hope nostr wallet connect starts supporting recurring payments more easily directly from the nwc service or from albyhub.
