Description
When a customer clicks "cancel" on your SaaS product, that's usually the last chance you get to save the relationship — offer a discount, pause the plan, or at least find out why they're leaving. RetainFast is a small widget you drop into your cancellation flow that catches that moment automatically, offers the customer alternatives to canceling outright, and tells you why people are actually leaving.
RetainFast is a Stripe-native cancellation-flow widget, delivered as under 5KB of dependency-free vanilla JavaScript, isolated via Shadow DOM to avoid CSS conflicts, and set up in about five minutes without requiring Stripe API keys. It offers a configurable editor for building cancel-flow offers (coupons, plan pauses, downgrades, custom actions) and a dashboard tracking funnel and save-rate analytics.
💬 Our review
The short version: RetainFast targets a narrow but high-leverage moment — the cancel click — and does it cheaply enough that the math works even for a small SaaS business.
Against Baremetrics or ProfitWell, which are broader subscription-analytics platforms, RetainFast's differentiator is that it's purpose-built for one job (the cancellation flow itself) and ships as a near-zero-dependency script that doesn't require handing over Stripe API keys, which lowers both the integration effort and the security surface. The real constraints are that it's Stripe-only, capped at one license per site and 2,000 cancel sessions a month on the standard plan, and doesn't do upsells beyond pause/downgrade — so it won't replace a full retention or lifecycle-marketing platform. For a Stripe-billed SaaS that just wants to stop losing customers at the cancel button without a big integration project, RetainFast's $25-then-$12/month pricing is easy to justify; larger platforms doing high cancellation volume or needing multi-payment-provider support will outgrow it.
