Apache-2.0 monetization infrastructure for AI, API and usage-based products. OpenMeter takes raw product or agent events, turns them into customer-level usage, applies entitlements and credit limits, models usage-based pricing, and carries charges into an invoice lifecycle. It can own that whole path or sit between your application and the payment, tax and accounting providers you already use.
Per-seat billing fits people. Agents create a different unit problem: one run may make three tool calls and another may burn hours of compute. OpenMeter gives a product team the missing middle between those events and the bill, including the limits that stop an agent or customer from consuming beyond an allowance. That makes it a practical build-vs-buy option for AI products whose pricing is part of the product design. The honest cost is operational: the evaluation stack is easy, but production means running event and analytics infrastructure, and you still need payment, tax and accounting providers around it.
