TL;DR
Churnkey is a specialized cancellation-deflection and involuntary-churn recovery tool — its cancellation flow builder, pause offers, discount offers and A/B testing on cancel flows are best-in-class for teams focused on saving customers at the moment they try to leave. RetentionLens includes a cancellation flow builder and dunning recovery, and adds predictive churn analytics (survival analysis / Cox model, customer health scoring) and causal uplift modeling on top — so you get both prevention and recovery in one Stripe-native platform, without needing a separate analytics tool.
Churnkey has earned a strong reputation for the quality of its cancellation-deflection product. Its flow builder, granular pause and discount offer controls, and A/B testing on cancel flows give product and growth teams the best-in-class tooling for saving subscribers at the exact moment they hit the cancel button. It also handles involuntary churn recovery through smart dunning. If the cancellation-flow UI and A/B testing experience is your single top priority and you already have analytics elsewhere, Churnkey is hard to beat.
RetentionLens covers the same recovery use cases — cancellation flows and dunning — and extends them with the predictive layer Churnkey does not have: survival analysis to score churn risk weeks ahead, causal uplift modeling to identify which customers respond to intervention, and a budget optimizer to allocate CS effort. The tradeoff is that Churnkey's cancellation-flow builder is more specialized and more deeply A/B-tested than RetentionLens's; RetentionLens wins on depth of analytics and the ability to act before the cancel moment.

Frequently asked questions
Is RetentionLens a Churnkey alternative?
Yes, for teams that want prediction and recovery in one platform. Churnkey is a specialized best-in-class tool for cancellation deflection and dunning with no analytics layer. RetentionLens includes cancellation flows and dunning, and adds predictive churn (survival analysis), customer health scoring and MRR/NRR analytics — so you get both the recovery and the prevention without a second tool. The trade-off: Churnkey's cancel-flow builder and A/B testing are more specialized.
Does RetentionLens do dunning like Churnkey?
Yes. RetentionLens includes automated failed-payment recovery (dunning) with smart retry scheduling and in-app recovery flows, similar to Churnkey's involuntary churn recovery. RetentionLens also predicts and prevents voluntary churn using survival analysis and customer health scoring — capabilities Churnkey does not offer.
Does RetentionLens have cancellation flows?
Yes. RetentionLens includes a cancellation-deflection flow builder with pause and discount offers. Churnkey's cancellation flow builder is more specialized, with deeper A/B testing controls. If hyper-specialized cancel-flow UX and A/B experimentation is your top priority and you already have analytics elsewhere, Churnkey has an edge there.
