Built for

SaaS builders adding subscriptions, one-time payments and customer portals. GoForLaunch focuses on practical launch blockers rather than enterprise-only vulnerability labels.

What gets checked

  • Webhook routes that do not verify the Stripe-Signature header
  • Handlers that parse JSON before calling stripe.webhooks.constructEvent
  • PaymentIntent, subscription or checkout writes without stable idempotency keys
  • Prices, quantities, coupons or trial lengths sourced from request body data

What you get back

Reduce double-charge and forged-webhook risk
Keep payment state derived from Stripe instead of client metadata
Spot billing bugs before users or launch traffic do
