PaidCheck
Catch Stripe billing leaks in your vibe-coded SaaS
PaidCheck compares Stripe with who has access in your app every night. It flags paying users with no access, cancelled users who kept it, double charges and failed webhooks. Free one-off leak report with a read-only restricted key; live secret keys refused.
Hey Product Hunt, I'm Frank, the solo maker of PaidCheck, writing from Lancaster, PA.
**Why I built it:** a lot of SaaS apps now get built with Lovable, Bolt, Cursor and Supabase, and the AI usually writes the Stripe checkout too. That code tends to work on the happy path. The trouble is at the edges: a webhook returns a 400, an email doesn't match, a cancellation never reaches the database. Nobody notices until a customer emails to say they paid and can't get in, or until you realize churned users never lost access.
**What it does:** PaidCheck compares Stripe with who actually has access in your app. It flags:
- 💸 people with an active or trialing subscription who are missing or inactive in your app
- 🚪 users who still have access although their subscription is canceled, unpaid, incomplete or past_due
- 🔁 likely double charges (same customer and amount, both succeeded, within 24h)
- 📭 Stripe events your webhook never acknowledged, plus disabled or missing endpoints
Every report shows revenue at risk and a fix for each issue.
**How it connects (read-only):** you give it a Stripe restricted key (rk_) with Read on five resources and None on everything else. sk_live_ keys are refused on purpose. On the app side, you paste a prompt into your AI builder. It adds a secret-protected Supabase function or HTTPS endpoint that returns only email, plan and active.
**Who it's for:** solo founders and small teams with a vibe-coded or small SaaS that takes Stripe subscriptions.
**Free:** a one-off leak report at paidcheck.app/report. Your keys are used for that one request and nothing is stored. There's also a sample report if you want to see the output before connecting anything.
**Pricing:** Solo is $19/mo for 1 app with daily checks, alert emails for new leaks and a Monday summary. Multi-app is $49/mo for the same daily checks on up to 5 apps.
**What I'd love feedback on:** is the setup clear? Is a restricted key plus a 3-field endpoint something you'd trust? Is there a leak I'm not checking for? I'll be here all day answering questions.
