ChartMogul
ChartMogul is the pick if the shutdown is your excuse to consolidate more than Stripe: 25+ billing integrations and the deepest cohort work in the category.
QuantLedger listed Paddle, Chargebee and Recurly connectors alongside Stripe. If you actually used those, ChartMogul is the natural landing spot: it normalizes Stripe, Chargebee, Recurly, PayPal and a long tail of other sources into one revenue view, and its cohort analysis goes further than anything QuantLedger shipped.
The free Launch tier covers you up to $120K ARR, which suits the indie founders QuantLedger targeted.
Two honest caveats. First, freshness: ChartMogul's help docs describe Stripe data as realtime with a 10-minute processing window, so it trails a pure webhook feed. Second, cost trajectory: Capterra reviewers (4.7/5 across 44 reviews) praise the product but some long-time customers describe prices doubling and then doubling again, which is a different world from QuantLedger's flat $299 ceiling at $2M MRR.
