Ever since I gave up on FossPay, I have been working on a Node + Vue based version of the same thing called Eleutheria Pay. Think of it as a layer overtop of Stripe to handle donations that can be self hosted. It is not at feature parity yet, but I hope to get there eventually. Right now it has stripe based one-time payments working. Is anyone interested in this being developed further and it being tailored more to Cloudron?
I am open to feature requests as well.

Demo (Use this card info: https://stripe.com/docs/testing#cards) : https://testsupport.atrilahiji.dev/
This has finally reached a 1.0.0 release that better reflects what I wanted this project to me. Its certainly not complex but thats precisely what I wanted. No user management. Nothing complex. Just a customizable page that looks professional(ish) and can serve its own donate button you can embed anywhere. I have updated the package accordingly and am waiting to hear back about whether or not it can be added to the store. That being said, to get a better idea of how many people actually want this I urge you to upvote this first post.
