Verdict

Our wildcard, Lago, ranks eleventh because it is an open-source, metering-first billing engine built for usage-based and hybrid pricing, letting engineering teams self-host and own the billing logic that AI and infrastructure products increasingly need.

What customers praise

Its event-based metering handles high-volume usage pricing cleanly, and the open-source core means no percentage-of-revenue lock-in.

What customers criticise

As a young open-source project its dunning, revenue recognition, and prebuilt integrations trail the commercial incumbents, and self-hosting needs engineering ownership.

Best for

Engineering-led teams that want open-source, usage-based metering and billing they can self-host and control.
