Lago

What is Lago?

Lago is an open-source metering and usage-based billing platform designed for technology and AI companies that need flexible pricing models. The platform provides event-driven usage metering capabilities, allowing businesses to track and bill customers based on actual consumption rather than fixed plans alone. The system supports hybrid pricing structures, combining subscription-based and usage-based billing components to accommodate complex pricing scenarios. Lago operates as both an open-source project and a managed cloud service, giving organizations the option to self-host or use the hosted version depending on their infrastructure preferences. The platform serves as an alternative to established billing solutions like Chargebee, Recurly, and Stripe Billing, particularly for companies requiring sophisticated usage tracking and dynamic pricing capabilities. Lago handles the technical complexity of metering customer interactions and calculating accurate charges based on defined metrics and pricing rules. Key features include accurate event-driven metering, support for multiple pricing models, and the flexibility of open-source architecture. The codebase is available on GitHub, allowing developers to inspect, modify, and contribute to the project. Lago is suitable for SaaS companies, API-driven businesses, and any organization with variable or consumption-based revenue models that need reliable billing infrastructure.
