I built this because Stripe tells you that someone cancelled but not why. Leavely adds a feedback modal to your cancel flow — one script, one function call. The user picks a reason, optionally leaves a comment, and the cancellation proceeds normally.
You can try it: https://leavely.space — free 14-day trial, no credit card.
Stack: Next.js, TypeScript, Stripe. Looking for feedback on the SDK and the dashboard.
