OpenMeter
What it is
OpenMeter measures usage, applies access controls, and supports billing for AI, API, SaaS, and developer-tool products. It aggregates usage events in real time and supports quotas, limits, notifications, and edge usage gating. Its product catalog handles plans, entitlements, credits, usage-based pricing, add-ons, discounts, and commitments. Billing features include subscriptions, prepaid credits, customer portals, and auditable outputs. OpenMeter provides a REST API, Node.js, Python, and Go client SDKs, plus 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. The Apache 2.0 project can be self-hosted, or teams can use managed Konnect Metering & Billing. OpenMeter Cloud states it is SOC 2 Type 2 compliant and encrypts data at rest with AES-256 and in transit with HTTPS/TLS. SAML single sign-on and role-based access control are supported. The pricing page publishes no numeric rates and directs visitors to sales, while linking to a free Konnect start option.
