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.
ClientSuccess

Its health score combines revenue, usage, adoption, feedback, engagement, and sentiment into a 360-degree customer view. Journey tools cover onboarding, collaborative tasks, playbooks, goals, and lifecycle automation. SmartCS can generate customer emails, summarize health feedback and NPS results, and turn meeting notes into summaries with next steps and sentiment. Shared portals, repeatable project templates, and document or asset collection support onboarding. Integrations include Salesforce, HubSpot, Zoho, Pipedrive, Slack, Microsoft Teams, Gmail, Outlook, Zendesk, Jira, Pendo, Mixpanel, Zapier, and Stripe. A read-only MCP server connects data to Claude and other AI assistants within user permissions. There is no free plan or self-serve trial. Pricing is on request and depends on customer success managers, modules, team size, contract length, and integrations. Implementation is usually 4–6 weeks, or 8–12 weeks for larger enterprises.
