Show HN: Rekko – Stripe app to recover failed subscription payments
AlexRST Monday, January 26, 2026Hey HN, I built a small tool to automate failed payment recovery for Stripe subscriptions.
Context: I run a SaaS on the side and got tired of losing customers to expired cards. Stripe's built-in retries help but the recovery rate is meh. I wanted something that would ping customers via email and SMS right when a payment fails, with a fresh billing portal link.
It's a native Stripe app so setup is just OAuth, no webhooks to configure manually.
Stack is Next.js, uses Stripe's billing portal API to generate session links on the fly (so no expired links).
Still early, looking for feedback from anyone running subscriptions on Stripe. Free access for early testers.
Curious what others are using for this. I looked at Churn Buster and Dunning but they're overkill (and expensive) for small SaaS.
