OpenMeter

Usage metering and billing for AI, API, SaaS and developer tools

Visit OpenMeter

OpenMeter is an open source metering and billing platform for AI, API, SaaS, and developer-tool products. It addresses the infrastructure work behind usage measurement, entitlements, pricing, invoicing, and customer usage visibility: engineering teams send CloudEvents-compatible usage data, product teams define packaging and pricing, and finance teams receive auditable billing outputs from one system.

The platform supports real-time aggregation, a product catalog with plans, entitlements, credits, and usage-based pricing, subscriptions, prepaid credits, usage limits, customer portals, notifications, and integrations such as Stripe. It includes SDKs for Node.js, Python, and Go, collectors for AI tools and cloud infrastructure, and usage insights surfaced into CRMs and customer data platforms. Security features include SOC 2 Type 2, SAML SSO, RBAC, audit logs, and encryption at rest and in transit.

OpenMeter can be self-hosted under the Apache 2.0 license or used as the managed Konnect Metering & Billing offering on the Kong Konnect platform. A free starting option is available, with an enterprise tier that includes an uptime SLA; contact sales for pricing details.
