## What Lago Does

Lago is an API-first, self-hostable usage-based billing and invoicing platform.
It handles the full billing lifecycle: metering events, plan management, invoicing,
cash collection, and revenue analytics — for any pricing model.

## Core Capabilities

- **Usage metering** — real-time aggregation of any billable event (API calls, tokens, seats, GB, minutes)
- **Hybrid billing** — combine subscriptions, usage-based, prepaid credits, and enterprise contracts in one plan
- **Invoicing & credit notes** — automated invoicing with tax support, credit notes, and adjustments
- **Cash collection** — dunning, payment retries, and flexible collection workflows
- **Entitlements** — manage feature access directly in the billing layer
- **Revenue analytics** — MRR, ARR, churn, and usage trends across all revenue streams
- **Lago Embedded** — white-label billing for platforms and marketplaces
- **Lago AI** — AI-powered billing intelligence for anomaly detection and insights

## Deployment

- **Cloud** — hosted by Lago, fully managed
- **Self-hosted** — deploy on your own infrastructure (Docker, Kubernetes, AWS, GCP, Azure)
- **Open source** — GNU Affero General Public License v3.0, full codebase on GitHub
