What it is

OpenMeter is an open-source platform for measuring product usage, controlling access, and supporting billing for AI, API, SaaS, and developer-tool products. It combines a REST API, client SDKs for Node.js, Python, and Go, and collectors for systems such as Kubernetes, S3, OpenTelemetry, PostgreSQL, ClickHouse, LangChain, Prometheus, Nvidia Run:ai, and Redpanda Connect. Usage events can be aggregated in real time, with quotas, limits, notifications, and edge usage gating. Its product catalog handles plans, entitlements, credits, usage-based pricing, add-ons, discounts, and commitments. Billing supports subscriptions, prepaid credits, customer portals, auditable outputs, proration, tax automation, and multi-currency billing. Stripe can synchronize invoices and assist with tax calculation and payment collection. Teams can self-host under the Apache 2.0 license or use Konnect Metering & Billing. OpenMeter Cloud states SOC 2 Type 2 compliance, AES-256 encryption at rest, HTTPS/TLS in transit, SAML single sign-on, and role-based access control. The free plan has no numeric rates published; pricing directs visitors to sales.
