Rationale

Lago offers a billing engine with features like usage metering, price plans, coupons, add-ons, and invoicing. It provides an API for integration and a customer portal. While it integrates with payment processors like Stripe, it is not a payment processing platform itself, but rather a billing and subscription management tool. It lacks direct payment processing, fraud detection, and many of the 'other' Stripe-specific features.
