Sounds right. People will let you do subscriptions but doing a pay per use plan sounds annoying, especially with something like this where the result may not always be what they hoped for (no offense). Puts you in a tricky situation of having to guess how much people will use it.
Couldn't it just be client side code on a website though? I've barely looked at web tech but like, there are whole games that run client side. The PWA stuff google was pushing should let clients cache it all too I thought. If you're already open source seems like that'd work.
Payments probably still annoying though. Ideally billing provider should keep subscription list and UI for customers to manage it centrally, like Msft\Apple\Google app stores do. Paypal does this, but feels kind of limiting to only support Paypal.
