Frequently Asked Technical Questions (Lago)

Can I self-host Lago in my infrastructure?

Yes, Lago provides an open-source edition that can be deployed independently in your own cloud or VPC, allowing teams with strict compliance needs to retain control over their billing data.

How does Lago handle AI token-based billing?

Lago uses a metering engine to capture usage events in real-time, allowing you to apply dynamic rates for tokens (input/output/cached) and generate automated invoices based on actual consumption during the cycle.

Am I locked into a specific payment gateway?

No, Lago acts as an orchestration layer for billing. You define your pricing logic within Lago, and the platform coordinates the transaction through your preferred payment processor.
