Lago

What is Lago?

Lago is an open-source billing and invoicing platform for usage-based and subscription pricing. It can run as managed Lago Cloud or be self-hosted on-prem or in your own VPC.

Key features of Lago

• Billable metrics and usage ingestion: Ingest events and meter them for billing, with real-time usage alerts.
• Pricing models: Entitlements, custom pricing units, plan overrides and prepaid credits.
• Invoicing: Invoice generation, grace periods, credit notes and progressive billing.
• Payments and dunning: Payments integration and automatic dunning.
• Analytics and AI: Analytics dashboard, AI Billing and Finance Assistants and an MCP server.
• Security: RBAC with custom roles, audit logs and SSO via Okta.

How Lago works

Your product sends usage events to Lago, which aggregates them into billable metrics, applies plans and generates invoices. Payments, tax and accounting connections extend it. Teams can contribute to the open-source project on GitHub.

Who uses Lago?

Lago is used by product and finance teams at software companies with usage-based or hybrid pricing who want control over billing logic, including the option to self-host.

Lago pricing

Lago does not publish prices; its pricing page directs visitors to book a demo. Deployment options are managed Lago Cloud or self-hosted, and the feature comparison covers Lago Premium on both. Some features are add-ons on request.

Lago integrations

Lago lists payments and tax integrations, CRM, CPQ and accounting integrations as add-ons, plus data pipeline, SMTP and custom branding options.

Lago alternatives
