Spotsaas Analysis for Lago
Lago is an open-source usage-based billing platform for SaaS companies handling metering, aggregation, invoicing, and payment collection for complex pricing models.
What is Lago?
Lago is an open-source metered billing and usage-based pricing infrastructure platform. It allows SaaS companies to implement complex pricing models — per-seat, usage-based, hybrid, and consumption pricing — with a billing engine that handles metering, aggregation, invoicing, and payment collection. Available as self-hosted (open source, MIT license) or cloud-hosted, Lago is the developer-first alternative to Stripe Billing, Chargebee, and Maxio for companies building usage-based or hybrid pricing models. Backed by $22M in Series A funding.

Who should consider Lago
- Use cases
- SaaS companies with complex usage-based pricing (AI platforms, API businesses, infrastructure tools) that Stripe Billing cannot model cleanly, Engineering teams that want to self-host billing infrastructure for data residency or compliance reasons, Startups implementing usage-based pricing from the start and wanting a flexible, open-source billing foundation they can grow into
- Team types
- Small Business, Mid-Market
Why teams choose Lago
Open-source with MIT license provides true ownership — teams can self-host, modify, and extend the billing engine without vendor lock-in or licensing fees.
Purpose-built for complex usage-based pricing that Stripe Billing handles poorly — aggregation, tiered rates, minimum commitments, and hybrid models are native.
Real-time event ingestion API handles high-volume metering at scale, making it suitable for API-first and AI products with millions of daily billable events.

What buyers should know before shortlisting Lago
Lago fills a genuine gap in the billing infrastructure market: most billing tools were built for subscription pricing and struggle with the metering, aggregation, and tiered consumption models that usage-based SaaS companies need. By open-sourcing the billing engine and providing a developer-first API, Lago has attracted strong adoption among technical teams who need billing flexibility without the constraints of Stripe Billing or the enterprise overhead of Maxio.
The self-hosting option is particularly compelling for companies with data residency requirements or who want full control over billing data. The cloud pricing starts at a level that may not make sense for pre-revenue companies, but for companies with meaningful MRR building on usage-based models, Lago is one of the most technically capable billing platforms available.

- Lago cons
Self-hosting requires DevOps expertise and ongoing infrastructure management — the free tier is genuinely free but has a meaningful operational overhead cost.
Cloud pricing starts at $500/month, which may be expensive for early-stage companies with low MRR who want managed hosting rather than self-hosting.
