What they built

Questions people ask

What is Lago?

Lago is an open-source billing platform for usage-based, subscription, prepaid, and hybrid pricing. It connects product usage and commercial terms to customer invoices.

How do applications integrate with Lago?

Applications connect to Lago through a REST API, official SDKs (JavaScript, Python, Ruby, Go), and signed webhooks. The public OpenAPI spec and developer docs walk through each integration path.

Can teams run Lago on their own infrastructure?

Yes. Lago is AGPLv3-licensed and open source, so you can self-host it on your own infrastructure, or run it as a managed cloud service instead.

How much does Lago cost?

The open-source version is free to self-host under an AGPLv3 license. Lago Premium, available on Cloud or self-hosted, isn't publicly priced, since deployment size and needs vary; the team shares pricing directly when you book a demo.

How is Lago different from Stripe Billing, Chargebee, or Zuora?

Lago is open source, so teams can inspect the code, self-host it, and extend it rather than depend on a closed platform. It's built to handle usage-based, subscription, prepaid, and hybrid pricing on the same billing engine, without locking that flexibility behind a single vendor's roadmap.
