Show HN: DeclineKit – Open-source failed payment recovery for Stripe (github.com)

I built DeclineKit a few weeks ago, and have been trying to get new customers for it.

Since people need to add a Stripe key to use it, there was definitely some skepticism making one for a random website on the internet.

To combat that, I made it a Stripe App available in their marketplace. You can connect it directly in Stripe.

And then I went a step further and just open-sourced everything. You can set it up and run it. yourself. Or just use the hosted version.
