Innovative billing solutions, tailored for engineers

Unleash open-source billing's potential with API-First technology for high-volume event ingestion. Empower engineering teams with our agnostic billing solution, designed for flexible and efficient billing engines.

Open Source

There’s no black box effect with Lago, inspect our code base, submit an issue or a pull request if you’d like a change. Because it’s easier to understand how we built Lago, it’s also easier for you to build on Lago. We have a community of 700 billing engineers and product managers you can share use cases or questions with.

API-First, high-volume event ingestion

Lago was built by billing engineers with years of experience in scaling a home-grown billing system. We built Lago for flexibility, with an event-based architecture that can ingest hundreds of thousands events per second. Lago has been starred nearly around 4,000 times in a year, more than any other Github repository in this space.


Lago is agnostic and compatible with your current and future internal tool stack. You shouldn’t be married with a payment processor, accounting software, or any other tool for that.
