TL;DR
QuantLedger has been decommissioned and is no longer available. It was a Stripe-native subscription-analytics tool with machine-learning churn prediction, positioned as a Baremetrics and ChartMogul alternative. RetentionLens is the closest like-for-like replacement: Stripe-native setup, MRR / NRR / cohort analytics, predictive churn via survival analysis (Cox model), customer health scoring, and a free Starter tier — so former QuantLedger users can keep the same workflow.
If you are here looking for QuantLedger, note that the product has been shut down — its site now serves a decommission notice. That leaves teams who relied on it for Stripe analytics and ML churn prediction needing a replacement.
RetentionLens is built for exactly that profile. It connects to Stripe in minutes, rebuilds your MRR, NRR, churn and cohort retention, and adds predictive churn scoring using survival analysis plus customer health scores — the same forward-looking layer QuantLedger offered. It has a free Starter tier, so you can move over and see your numbers before committing budget.

Frequently asked questions
Is QuantLedger still available?
No. QuantLedger has been decommissioned and its service is shut down; only some blog content remains online for reference. Teams that used it for Stripe analytics and churn prediction need an alternative.
What is the best QuantLedger alternative?
RetentionLens is the closest like-for-like replacement. Like QuantLedger, it is Stripe-native and offers MRR, ARR, NRR, cohort retention and predictive churn — RetentionLens uses survival analysis (a Cox proportional-hazards model) plus customer health scoring — and it has a free Starter tier to start on.
Can RetentionLens import my QuantLedger data?
RetentionLens rebuilds your metrics directly from Stripe, so you do not need to migrate QuantLedger exports to get accurate history — connecting Stripe backfills your MRR, churn and cohorts automatically. Keep any QuantLedger exports for your own records.
How quickly can I switch?
Setup is connect-and-backfill. Most teams see their first charts within minutes of connecting Stripe. Predictive models activate once there is enough history (roughly 100+ customers and a number of churn events).
