OpenMeter

What is OpenMeter?

OpenMeter is an open-source metering and billing platform designed for AI, agentic, and DevTool companies. It provides flexible usage metering infrastructure that enables organizations to track consumption and implement billing based on actual usage patterns. The platform addresses the needs of SaaS and platform companies that require granular billing capabilities tied to specific metrics or resources consumed by their customers. OpenMeter allows developers to define custom meters, aggregate usage data, and generate billing records without being locked into proprietary solutions. Available in two deployment models—self-hosted open-source and a managed cloud service—OpenMeter gives teams flexibility in how they operate their billing infrastructure. The self-hosted option allows complete control and customization, while the managed offering reduces operational overhead. Key differentiators include its open-source nature, which eliminates vendor lock-in, and its particular focus on the metering challenges specific to AI and DevTool companies where usage patterns and billing requirements differ from traditional SaaS models. The platform is actively maintained with documentation, API references, and community contribution pathways available through its GitHub repository. OpenMeter serves development teams, finance operations, and product managers who need transparent, flexible, and customizable billing infrastructure for their applications.
