What is OpenMeter?
OpenMeter is an open-source usage metering and billing platform designed for AI, API, and DevTool companies to implement usage-based pricing. It collects and aggregates millions of usage events in real-time using stream processing with Go, Kafka, and ClickHouse, enabling scalable metering that handles any volume of ingest. The platform provides a monetization tech stack that developers can easily integrate with their services via SDKs for Node.js, Python, and Go, while product teams can use the no-code UI to quickly ship new products and iterate on pricing without code changes.
Key features include real-time metering and usage limits with low-latency enforcement, flexible product catalog supporting plans/credits/usage-based pricing/commitments, entitlements and usage limit enforcement, billing and invoicing with Stripe integration, consumer portal for customers to monitor usage, and revenue insights that surface upsell opportunities and churn risks to sales teams in their CRM. OpenMeter continuously correlates customer usage with product purchases in real-time to derive insights that help revenue teams maximize value extraction and increase net revenue retention.
OpenMeter is ideal for AI companies needing per-millisecond compute billing, API providers tracking usage per customer, SaaS companies implementing usage-based pricing models, DevTool companies metering cloud infrastructure usage, and IoT applications with event-driven analytics requirements. The platform is available as open-source software under Apache 2.0 license on GitHub, or as OpenMeter Cloud, a managed SaaS offering that is enterprise-ready and SOC2 Type 2 compliant.
The platform supports collectors for AI tools, cloud infrastructure, and frameworks, making it easy to meter usage from various sources. It includes deduplication, flexible usage attribution of events to billable customers, and external usage syncs. OpenMeter is designed to handle the complexity of consumption-based SaaS revenue at the intersection of real-time data computation, plug-and-play pricing policies, and orchestrating workflows across Finance, Sales, Revenue Ops, and Engineering teams.
