About the Company

Lago

Open-source API-first metering and billing platform

Lago provides an open-source, API-first platform for metering and usage-based billing designed for complex pricing models. It processes high-volume event data to handle real-time metering, subscription management, entitlements, credits, invoicing, and revenue analytics, and integrates with Stripe, CRMs, and ERPs; it is the central billing logic, not a payment processor. Lago differentiates itself with an open-core model (free AGPLv3 self-hosted) plus paid cloud and premium self-hosted deployments, offering transparency and control to reduce vendor lock-in. Its goal is to help AI, SaaS, and API-first businesses monetize complex pricing at scale with a flexible, scalable billing infrastructure.
