OpenMeter is an open-source metering and billing platform for AI, API, and DevOps products that ingests high-volume usage events, aggregates them in real time, and turns them into usage-based billing, entitlements, and invoices. It exposes a REST API with SDKs, integrates with Stripe and tax providers, and can be self-hosted on Kubernetes or used as a cloud service.

Use cases

• bill customers based on API request usage
• meter AI token usage and charge per token
• enforce usage limits and quotas for free tiers
• track Kubernetes pod CPU and memory usage for customer billing
• sync usage data to Stripe invoices
• implement prepaid credits and entitlements
• build real-time customer usage dashboards
• support tiered and per-unit pricing models

When to choose

• you offer usage-based or hybrid pricing and need a single source of truth for consumption
• you need real-time metering at high event volume with entitlement enforcement
• you want billing infrastructure that integrates with your existing payment and tax providers
• you need self-hostable monetization infrastructure with an API-first design

When to avoid

• you only need fixed recurring subscriptions without usage metering
• you want a bundled operator UI, payment processor, or full accounting system
• you need a fully stable product with no breaking changes, since releases are beta
