ChurnWin pricing detailsChurnkey
Starter displayed at $250/mo for eligible teams
Churnkey combines cancel flows, payment recovery, experiments, analytics, and an MCP server whose permissions can include building and publishing retention changes.
Official pricing and product detailsPricing caveat: Churnkey displays Starter at $250 per month for teams with less than $5k in monthly churn volume, while larger-volume Core and Intelligence plans use different qualification and quote paths. Its pricing page says the SDK and MCP server are free on every plan. Verify current eligibility, billing term, and included products before purchase.

Best fit by team
Choose ChurnWin when…
Choose ChurnWin when a Stripe SaaS team wants read-only evidence and human-controlled actions, with cancellation themes and priorities exposed to agents without granting them production-write authority.
Choose Churnkey when…
Choose Churnkey when you want agent-authorized retention operations that can build and publish retention changes across cancel flows, dunning, and experiments under configured permissions.
Trade-offs to weigh
ChurnWin trade-offs
- ChurnWin does not execute dunning, retries, cancel flows, outreach, or billing changes; a human or separate system must act on its evidence.
- Its narrower Stripe-first workflow is not a replacement for Churnkey's broader retention automation stack.
Churnkey trade-offs
- Churnkey's MCP can receive write-capable, role-scoped permissions, so teams should review consent, confirmation, audit, and revocation controls before enabling production actions.
- Starter eligibility depends on monthly churn volume; larger teams should compare the applicable plan rather than the headline entry price.
Migration and switching notes
- Inventory every live cancel flow, dunning campaign, experiment, and billing behavior before replacing any retention automation.
- If testing ChurnWin alongside Churnkey, keep Churnkey's live recovery workflows active and use ChurnWin only for read-only evidence until results are reconciled.
- Review the exact MCP scopes and approval model for each product; sharing the MCP label does not mean the tools carry the same authority.
Balanced decision
Choose Churnkey when your team wants agent-authorized retention operations across cancel flows, dunning, experiments, and analytics. Choose ChurnWin when you want lower-cost, read-only Stripe evidence and agent-readable priorities while humans retain control of billing, outreach, and production changes. The products can coexist: verify each current plan and permission scope before connecting production data.
