// EDITOR'S TAKE
OpenMeter is the closest on Orb's core strength, high-volume event metering with real-time aggregation, but you will pair it with something else for invoicing. Lago is the more complete billing system if you also need subscriptions and dunning, and Flexprice is the interesting middle ground with usage metering plus credit balances aimed at AI products.
