This is an alternative to Stripe Billing, not the core Stripe payment rails themselves. In fact, one would use Stripe or similar with Lago: https://docs.getlago.com/guide/payments/overview .

Tracking the edge cases around recurring payments, invoicing, pro-rated tier changes, and metered billing is hard! And Stripe Billing APIs aren’t the most fluent for many cases. It’s good to see new layers in the space.
