Hey there,
I have two browser extensions that each have a few thousand users where I want to switch to a Freemium model. The basic features of the extensions are free but more advanced features of the extension should require a one-time payment of $5-10.
Do you have any recommendations or experience on payment platforms that support JavaScript/WebExtension clients? What do you use for your website or extension?
I don't know how much revenue I can achieve with this yet, so the platforms should ideally be free or not too expensive.
I found Paddle (https://paddle.com/) which look to be a very good platform but looking at their docs, they only have libraries for native apps - not JavaScript/WebExtensions.
https://keygen.sh/ seems to be provider build on top of Paddle that supports JavaScript, but their monthly pricing is too expensive for projects like mine that may have >50 licenses but not too large revenue.
I made ExtensionPay for this purpose! I like it better than Gumroad because it doesn't require copying and pasting license codes which always confuses users. It also has a nice login flow.
For anyone curious: I now found https://gumroad.com/ to be a great platform as they offer a simple licensing system and validation API that can be called directly form the popup.
