Right now most sdk, have a vendor lock-in and they make it impossible to export your data..

So I built Wildberry, an open-source alternative to RevenueCat—a modern in-app purchase and subscription management system built with React and TypeScript. I coded/designed from 12PM -> 11PM on Saturday and 8AM -> 11PM on Sunday. There are still tons of features missing (I'm working on support for PlayStore billing next!) but I think it's reached that - buzzword alert! - MVP stage where I want to see if anyone's actually going to use the darn thing.

Here's an example Wildberry link: https://github.com/ProjWildBerry/wildberry . Here are some screenshots I took while making it: https://github.com/ProjWildBerry/wildberry/blob/main/front-e...

I think it has some potential. What do you guys think?
