Driftcheck vs Churnkey & Stunning: detection vs recovery
Churnkey and Stunning are failed-payment recovery tools. When a card declines, they act — smart retries, dunning email/SMS sequences, card-update pages, and (for Churnkey) cancel-flow churn deflection — to win the revenue back. They're built to recover money you're already losing on failed charges.
Driftcheck does the opposite job: it only detects. It compares Stripe against your app database (or a CSV) and emails a ranked list of silent billing drift, with evidence for each finding. It never retries a payment, never sends a dunning email, never deflects a cancel. These tools are complementary, not competing — Driftcheck finds the leaks; recovery tools act on them.
What Churnkey & Stunning do
Churnkey and Stunning are revenue-recovery / dunning platforms that connect to Stripe and act when payments fail. Stunning runs smart retries, customizable dunning email/SMS sequences, pre-dunning for expiring cards, and optimized payment-update pages. Churnkey adds the same recovery engine plus cancel-flow churn deflection (pauses, discounts, win-back offers), A/B testing, and analytics, across Stripe and other billing platforms.
The key difference
Churnkey and Stunning act on failed payments — they retry charges and send dunning to recover revenue. Driftcheck is detection-only: it surfaces billing drift with evidence and never touches your billing. Recovery tools fix what they can see (a failed charge); Driftcheck also catches leaks dunning never sees — plan/price drift, ghost customers, webhook gaps, subscription-state mismatch — because those aren't payment failures at all.
Side by side
| Driftcheck | Churnkey / Stunning | |
|---|---|---|
| Primary job | Detect billing drift between Stripe and your app DB, with evidence | Recover revenue from failed payments via retries + dunning |
| Acts on findings? | No — detection only. Never retries, duns, or deflects churn | Yes — smart retries, dunning email/SMS; Churnkey also deflects cancels |
| Data access | Stripe (read-only key) + your app DB / a CSV you upload | Stripe (read + write, to retry charges) and other billing platforms |
| What it uniquely catches | Plan/price drift, ghost customers, webhook gaps, subscription-state mismatch — leaks dunning never sees | Failed/declined charges and at-risk cancellations — the recovery surface |
| Setup | Paste a read-only Stripe key; optionally upload a CSV of your DB | Connect Stripe, configure retry rules + dunning templates (+ cancel flow) |
| Pricing | $12.99 one-time (key) · $20 one-time (key + CSV) · $29/mo monitor | Monthly subscription that scales with MRR / churn volume (see each tool) |
| Who it's for | Solo founders who want to know exactly what's wrong before acting | Teams that want recovery automated — retries and dunning on autopilot |
When Churnkey or Stunning is the better fit
Choose Churnkey or Stunning when your main problem is failed payments and you want recovery automated. If cards are declining and you want retries, dunning email/SMS, and card-update pages running on autopilot without building it yourself, these tools are exactly right — involuntary churn from failed payments is a real, large share of churn (Stripe reports roughly a quarter of lapsed subscriptions trace to payment failures), and recovering it is their core competency. Pick Churnkey if you also want cancel-flow deflection and deeper analytics; pick Stunning for a lean, Stripe-focused dunning tool.
When Driftcheck fits
Use Driftcheck when you suspect revenue is leaking but dunning isn't catching it — because the problem isn't a failed charge. A customer on the wrong (cheaper) plan, a ghost customer active in your app but not billed in Stripe, a webhook that silently failed so your DB and Stripe disagree, an expired coupon still applied — none of these trigger a dunning sequence, because no payment failed. Driftcheck finds them with evidence tracing to the exact Stripe object and the CSV cell that disagrees. Many teams run both: Driftcheck as the detection layer, a recovery tool as the action layer.
Questions
Is Driftcheck a replacement for Churnkey or Stunning?
No. Churnkey and Stunning recover failed payments by retrying charges and sending dunning. Driftcheck only detects billing drift and never acts on it. If you want automated recovery, you want them. They're complementary: Driftcheck finds leaks (including ones dunning never sees), recovery tools act on failed charges.
Does Driftcheck retry payments or send dunning emails?
No — and it never will. That's the wedge. Driftcheck is detection-only: read-only Stripe access, no retries, no dunning, no churn prediction. It surfaces what's wrong with evidence and leaves the action to you (or to a recovery tool).
Can I use Driftcheck alongside a recovery tool?
Yes — that's the intended setup. Run a recovery tool to win back failed payments, and run Driftcheck to catch the leaks recovery tools can't see: plan/price drift, ghost customers, subscription-state mismatch, and silent webhook failures. Detection layer plus action layer.
