OpenMeter

OpenMeter is a usage metering and billing platform, built by Kong, for companies that charge by consumption. It ingests events, logs and metrics at a rate of millions per second, aggregates them into accurate usage in real time, and turns that usage into invoices through integrations with payment providers such as Stripe and with CRM and tax systems. A product catalog handles plans, credits, usage based prices and commitments without code changes, and usage limits, quotas and notifications let a vendor gate access at the edge when a customer exceeds an entitlement. It is designed for developers and product teams at AI companies, API platforms and SaaS businesses. The canonical example on the site is metering large language model token consumption per customer, attributing every OpenAI call or serverless process so that each account stays profitable; collectors also cover Kubernetes, S3, OpenTelemetry, PostgreSQL and LangChain. SDKs are available for Node.js, Python and Go alongside a REST API, and the platform surfaces expansion signals from usage data into the sales team's CRM. Hosted deployments are SOC 2 compliant with RBAC and single sign on. OpenMeter comes in two forms. The open source engine is on GitHub under the Apache 2.0 license and is free to run. The hosted edition, formerly OpenMeter Cloud, is now sold as Konnect Metering and Billing on Kong's Konnect platform, described as the same team and the same product under a new name. It can be started for free, but Kong does not publish plan names or prices on the OpenMeter site and directs buyers to its sales team for pricing.
