Lago

Lago is an open-source metering and usage-based billing API designed for complex pricing and monetization. It offers features such as usage metering, price plans, coupons, add-ons, and invoicing. Lago targets AI, cloud, API, fintech, CPaaS, and DevTool companies, providing them with tools to scale faster.

Lago is a metering and usage-based billing API, which aligns with the 'Billing & Subscription Management' and 'Developer API Integration' features. The website mentions features like price plans, invoicing, and a customer portal, suggesting capabilities similar to 'Dashboard & Reporting'. While Lago doesn't explicitly mention payment processing or fraud detection, its focus on billing and usage suggests it integrates with payment gateways, but it is not a core feature they provide themselves.
