What OpenMeter is

OpenMeter measures product usage, applies access rules, and supports billing for AI, API, SaaS, and developer-tool products. It aggregates events in real time and supports quotas, usage limits, notifications, and edge usage gating. Its catalog covers plans, entitlements, credits, usage-based pricing, add-ons, discounts, and commitments. Billing features include subscriptions, prepaid credits, customer portals, and auditable outputs. Teams can use a REST API and Node.js, Python, or Go SDKs, alongside collectors for systems including Kubernetes, S3, OpenTelemetry, PostgreSQL, ClickHouse, LangChain, Prometheus, Nvidia Run:ai, and Redpanda Connect. The Stripe app can synchronize invoices and support tax calculation and payment collection; the marketplace also lists External Invoicing and Sandbox. OpenMeter is Apache 2.0 licensed and can be self-hosted, or teams can use managed Konnect Metering & Billing. OpenMeter Cloud states that it is SOC 2 Type 2 compliant and encrypts data at rest with AES-256 and in transit with HTTPS/TLS. It supports SAML single sign-on and role-based access control. Published pricing has no numeric rates; the pricing page directs visitors to sales and links to a free Konnect start option.
