Complex Pricing Tier And Overage Calculation

via “usage-based-metered-billing”

Open-source monetization API for developer tools.

Unique: Provides native metered billing without requiring custom aggregation logic, automatically tracking usage events and calculating tiered charges across billing periods with support for hybrid subscription + usage models

vs others: Simpler to configure than building custom usage tracking on top of Stripe, with built-in support for combining base subscriptions with metered overages in a single billing system
