Someone built a command line tool to pay sats to all project deps on github assuming the deps had a payment file in their root or something.
It was posted on SN over a year ago but my memory or our search isn't good enough for me to find it.
I think it's already possible with Alby if you put a certain meta tag on your website. That is custodial indeed, but it's a first start to get going for some. Then you could have non-custodial and custodial Lightning options.
