Metronome: Usage-based billing platform with focus on monetization and pricing strategy
Overview
What Lago does
Lago is an open-source billing platform designed for AI, SaaS, fintech, IoT, and infrastructure companies requiring flexible, high-volume billing solutions without vendor lock-in. Built on an API-first architecture, Lago combines real-time usage metering across API calls, tokens, compute, storage, seats, and custom dimensions with support for multiple pricing models including subscription, usage-based, prepaid, and hybrid approaches. The platform handles automated invoicing, taxes, credit notes, and multi-currency support, with entitlements tied directly to plans. Lago offers deployment flexibility with options for cloud hosting, VPC, on-premise, or self-hosted configurations. The open-source codebase is available under the AGPLv3 license, and the company has raised $22 million in funding from tier-1 investors including Firstmark Capital, SignalFire, and Y Combinator.

Softwr does not host reviews and shows no star rating for Lago, because a rating we did not collect is not ours to publish. What is here is the pricing and platform detail from the vendor’s own pages, limitations we could state concretely, and alternatives a reviewer confirmed people weigh against it.
