Basically you don't need to run your own server / database / custom Stripe integration code / user management system / custom extension integration, which is annoying to write yourself and costs money to run a server. With ExtensionPay you just add a little code in your extension [open source here](https://github.com/Glench/ExtPay) and register your extension in the web UI. I made it for use in my own extensions :)
> BTW I think someone was trying to start a browser extension developer guild on HN, can't remember which thread... You should tap into that community.
Cool, I'll check it out, thanks. Any other hints to how I could find it?
