TL;DR

Lago is an open source billing platform for usage-based, subscription, and hybrid pricing. It replaces custom billing code and proprietary billing infrastructure when product-led companies need metering, invoicing, entitlements, and payment orchestration under their control. Best for SaaS teams with pricing models that Stripe Billing alone does not model cleanly.

who it's for

Who Lago is for#

SaaS teams with usage pricing

Lago fits products that bill by seats, events, credits, usage tiers, or hybrid models where simple recurring plans are not enough.

Skip if:

Skip if your pricing is a single flat monthly subscription handled cleanly by your payment processor.

Platforms needing billing ownership

Use it when billing data, entitlement decisions, and payment routing need to stay inspectable and portable.

Skip if:

Skip if finance operations require a fully managed enterprise billing suite first.

the problem

The problem it solves#

Billing becomes risky when product usage, plan entitlements, invoices, payment providers, and revenue reporting all live in separate systems. Teams either build billing logic into application code or accept proprietary workflows that are hard to inspect when money, taxes, and customer access are on the line.

how Lago solves it

How it solves it#

Usage and subscription billing

Supports usage-based, subscription-based, and hybrid pricing models with real-time event ingestion and aggregation.

Payment-agnostic architecture

Works with Stripe, Adyen, GoCardless, or another gateway instead of forcing one payment processor.

Entitlements and revenue workflows

Connects feature access, invoicing, cash collection, revenue analytics, embedded billing, and integrations around one billing platform.

strengths · trade-offs

Strengths and trade-offs#

Strengths

  • Billing logic you can inspectLago gives teams source access for billing workflows that are often trapped inside a proprietary billing vendor.
  • API-first billing operationsThe README states every feature is available through the REST API, which fits product-led billing automation.

Trade-offs

  • -Billing infrastructure demands careRunning billing yourself means you own uptime, data accuracy, invoice testing, and payment-provider integration behavior. A managed billing vendor may reduce operational load.
versus alternatives

Lago vs alternatives#

Lago vs Stripe Billing

Lago is the stronger choice when usage metering, entitlements, and billing rules need to live in an inspectable open source platform. Stripe Billing is still a better fit when a team wants the shortest path to managed subscription billing inside the Stripe ecosystem.
