The short answer

Both sides assessed

Churnkey compared with Stunning

Stunning is failed-payment recovery only, on Stripe, Foxy, and Subbly, priced on a sliding MRR scale from well under $150 a month at small sizes. Churnkey adds cancel flows and costs more. If your churn is mostly declined cards and you are on Stripe, Stunning does that job for less; if you also need to intercept people clicking cancel, Churnkey is the one product that does both.

Stunning compared with Churnkey

Churnkey covers both involuntary and voluntary churn and starts at $250 a month billed yearly; Stunning covers involuntary churn only and costs roughly half that at comparable sizes. If failed cards are your whole problem and you are on Stripe, Stunning gives you more recovery channels for less money. If you also need to intercept people clicking cancel, Churnkey is the single-vendor answer and worth the premium.

Choose Churnkey if

Subscription SaaS companies past roughly $30,000 MRR that are losing meaningful revenue to both cancellations and failed cards, run on Stripe, Chargebee, Paddle, Braintree, or Maxio, and want one vendor and one install covering both problems rather than stitching a dunning tool to a cancel-flow tool.

Choose Stunning if

Stripe-billed SaaS and subscription companies from roughly $10,000 MRR upward that want the involuntary-churn problem solved properly and cheaply, particularly small teams who would otherwise be relying on Stripe's default retries and a single generic failure email.

Setup time	The vendor claims 35 minutes and that is roughly honest for the cancel flow: connect the billing provider, configure a flow in the dashboard, and swap your cancel button for a Churnkey call using the React SDK or snippet. Payment recovery is faster because it needs no front-end work at all beyond optional in-app prompts.	Minutes for the core product. Connect Stripe, choose from pre-written templates, and dunning is live. Adding your own branding, a custom domain for the update pages, and the in-app notification bar takes a little longer and is worth doing before you judge results.
Learning curve	Low to operate, moderate to do well. Anyone can turn it on. Designing offers that save revenue without giving away margin is a genuine skill, and the default of offering a generous discount to everyone is the mistake most teams make in month one.	Very low. There are no tiers to reason about and no offers to design. The only real decisions are cadence and copy, and the templates ship with sensible defaults.

Strengths and limitations

Churnkey

Strengths

One vendor and one install covers both involuntary and voluntary churn, with the results reported separately so you can tell which half is actually working.
Flat pricing with no percentage of recovered revenue, which is meaningfully cheaper than revenue-share competitors once you are above roughly $50,000 MRR.
Cancel flows execute billing changes themselves, so adding a pause offer does not require your engineers to build pause logic in Stripe.
Published aggregate benchmarks from millions of cancellation sessions give you a realistic starting point for offer design instead of guessing.

Limitations

Entry pricing of $250 a month billed yearly excludes most companies under $20,000 MRR, which is a large share of the small businesses this tool would otherwise help.
Core and Intelligence prices are not published, so you cannot budget without talking to someone or starting a trial.
The interesting 2026 AI features all sit on quote-gated tiers, meaning the genuinely self-serve product is the more conventional one.
Billing provider support is SaaS-shaped: Stripe, Braintree, Chargebee, Paddle, and Maxio. Ecommerce subscription stacks like Recharge, Skio, and Loop are not covered.

Stunning

Strengths

The deepest recovery channel mix at this price: Smart Retries, backup payment methods, email, SMS, in-app bars, pre-dunning, abandonment emails, and unpaid reactivation.
Every feature is included on every plan, so there is no tier gaming and no feature discovered to be locked after purchase.
Priced well below Churnkey and Churn Buster at comparable revenue, which makes it the realistic dunning choice for a small company.
Thirteen years of operation and a claimed $13 billion recovered, with the specific edge-case features that only come from that much time in one problem.

Limitations

Only three payment stacks: Stripe, Foxy, and Subbly. Stripe is effectively the only real integration, and if you are not on it the product is unavailable to you.
No cancel flow, no deflection offers, no pause or discount interception. Voluntary churn is entirely outside the product's scope.
No subscription analytics, health scoring, or playbooks, so it will always be one tool among several rather than a platform.
Pricing is a slider rather than a published table, so you have to visit the site and enter your MRR to learn your number.

Pricing compared

Churnkey

Flat monthly subscription banded by how much revenue you lose to churn each month, not a percentage of recovered revenue and not per seat. Only the entry price is published.

Starter$250
CoreNot published
IntelligenceQuote
EnterpriseQuote

Churnkey is priced for companies that already have a churn problem worth paying to fix. If you are losing $5,000 a month, $250 buys a plausible 20 to 40 percent reduction and the math is easy. If you are losing $800 a month, no configuration of this product returns its cost and you should be using Stripe's free smart retries and a hand-rolled survey instead. The flat fee is the correct long-run structure and becomes a serious advantage over revenue-share competitors once you scale, but the unpublished Core pricing and the yearly-billed entry point mean the true cost of entry is a $3,000 annual commitment, and that is a real decision rather than a trial.

Stunning

Sliding scale based on MRR, with every feature included on every plan. No feature tiers, no per-recovery fees, and no percentage of recovered revenue.

Single plan, sliding scaleApproximately $120 at $40,000 MRR

This is the best price-to-capability ratio in the involuntary-churn half of this category. Around $120 a month at $40,000 MRR buys more recovery channels than Churnkey's $250 Starter plan does, and the every-feature-included structure means the price you see is the price of the whole product. What you are giving up is scope and modernity: no cancel flows, no analytics, no AI, no offers, and a processor list of exactly three. If you are on Stripe and your problem is failed payments, nothing here is worse than the more expensive options and several things are better. If your problem is people deliberately cancelling, Stunning does not address it at all and its low price is irrelevant to you.

Editorial verdict on each

Churnkey

Category Leader

Churnkey is the most complete answer in this category for a SaaS company on Stripe or Chargebee that has both problems: cards failing and customers cancelling. Doing both in one install, with the results reported separately, is genuinely more useful than assembling a dunning tool and a cancel-flow tool, and the flat fee ages well as you grow while revenue-share competitors get more expensive. The two real objections are price and transparency. A $250 minimum billed yearly puts it out of reach for the smallest companies, who should use free smart retries first, and the unpublished Core and Intelligence pricing is a bad look for a vendor that otherwise sells itself. Buy it once you are losing enough revenue that a few hundred dollars a month is obviously cheap, which for most companies means somewhere north of $30,000 MRR.

Stunning

Stunning is the correct first purchase for a Stripe-billed small business with a failed-payment problem. It costs roughly half what Churnkey's entry plan does, includes every feature at every price point, and works the recovery through more channels than anything else at this level: retries, backup cards, email, SMS, in-app banners, pre-dunning, abandonment follow-ups, and automatic reactivation of unpaid accounts. Fourteen years of doing one job shows in the details. The two boundaries are absolute rather than negotiable. It works on Stripe, Foxy, and Subbly and nothing else, and it does nothing whatsoever about customers who deliberately cancel. Accept both and it is the best value in this category; need either fixed and you are shopping elsewhere.
