I don't think there's any tool or platform that allows subscription based services with Bitcoin. That's a critical feature of Patreon.

If anyone knows about a way to make subscriptions with Bitcoin (say, pay 10k sats a month), then it would be great to share it here. But as far as I know, it can only be done in custodial ways.

The closest that I've seen for a solution to this is Alby, which allows you to do something like that, setting a maximum spend per website, and not asking for permission whenever there's a new charge.
