In their own words
Churnkey
Churnkey provides subscription retention tools for cancellation churn and failed payment recovery. Cancel Flows use customer segmentation to present offers such as cross-sells, pauses, discounts, and seat handoffs. Payment Recovery combines precision retries with email, SMS, or in-app campaigns. Feedback AI categorizes freeform feedback, connects it to MRR, and supports natural-language search. Listed integrations include Stripe, Chargebee, Braintree, Paddle, Maxio, Slack, APIs, and webhooks; the SDK can connect to other billing systems. The open-source React SDK and MCP server are free on every plan, and cancel flows can be self-hosted without a Churnkey account. Free Churn Metrics provides a read-only churn snapshot when a payment provider is connected. Churnkey lists a free plan and a paid Starter plan at $250/mo (annual), with a 14-day trial. It identifies SaaS, consumer memberships, nonprofits, news and media, and streaming as use cases.
