CancelKit: Turn cancellations into saved revenue — free, no card

Hey Product Hunt 👋 I built CancelKit because my own SaaS was leaking MRR at the cancel button — someone would click cancel, and I'd never find out why, and never got a chance to save them. CancelKit drops a one-line script on your Stripe cancel flow: a quick exit survey + an instant save offer (discount or pause) before the cancellation goes through. I originally built a full billing layer on top of it. I ended up ripping it out entirely — gating cancel-reason data behind a paywall made no sense for a tool whose whole point is that almost nobody measures this. It's free now: no card, no paid tier, one line of script. Would love feedback, especially from anyone who's fought with Stripe subscription churn.
