What is ChurnKit?

ChurnKit is a behavioral churn prediction engine. It ingests events from your product, scores each user’s churn risk in real time, and fires webhook alerts when users cross configurable risk thresholds — so your team can act before they cancel.

​
Core capabilities

Event Tracking

Track any product event — logins, feature usage, support tickets, plan changes.

Risk Scoring

Get a 0–1 churn risk score with tier classification and actionable recommendations.

At-Risk Users

Paginate or stream all at-risk users above a threshold for bulk intervention.

Webhook Watches

Set per-user webhooks that fire when risk exceeds a threshold, with cooldowns.

​
How risk scoring works

ChurnKit’s scoring model considers:
  • Recency — how recently the user was active
  • Frequency — how often they use core features
  • Depth — breadth of feature adoption
  • Trajectory — whether engagement is trending up or down
  • Plan signals — trial expiry, downgrade history, support volume
The model outputs:

Typical integration flow

User signs up → identify()
User logs in → event('session_started')
User uses feature → event('feature_used', { feature: '...' })
Cron / webhook → score() or watch() alerts your team
Team reacts → email, in-app nudge, CS outreach
