Real-time usage metering and billing for AI and DevOps
OpenMeter delivers real‑time usage collection, flexible usage‑based billing, and automatic limit enforcement for AI, API, and DevOps services, with self‑hosted Kubernetes deployment or a cloud SaaS option.
OpenMeter is built for AI SaaS providers, API platforms, and DevOps tools that need to track consumption at scale. Whether you are a startup launching a pay‑per‑use model or an enterprise looking to add granular cost controls, the platform offers the observability and billing flexibility required.
The system ingests millions of usage events in real time via Kafka, stores them in ClickHouse, and exposes a REST API with SDKs for JavaScript, Python, and Go. It supports custom pricing rules, usage‑based limits, and integrates directly with Stripe for automated invoicing. Real‑time dashboards give insight into consumption patterns, helping you enforce caps and optimize pricing.
You can run OpenMeter on your own Kubernetes cluster using the provided Helm chart, or start instantly with the managed cloud offering. A quick‑start Docker Compose setup lets you evaluate the product in minutes, while the open‑source Apache‑2.0 license encourages community contributions.
When teams consider OpenMeter, these hosted platforms usually appear on the same shortlist.
Looking for a hosted option? These are the services engineering teams benchmark against before choosing open source.
Kubernetes pod execution metering
Track pod runtime, enforce per‑pod usage caps, and generate detailed billing reports.
Stripe‑based usage billing for AI APIs
Collect API call data, calculate token‑based costs, and automatically invoice customers via Stripe.
Log‑driven metering for microservices
Parse service logs, aggregate events, and apply custom pricing tiers in real time.
Cloud‑hosted metering for rapid prototyping
Sign up, start sending usage events, and access real‑time dashboards without managing infrastructure.
Clone the repository, navigate to the quickstart folder, and run `docker compose up -d`. The demo UI and API will be available in minutes.
Yes, OpenMeter Cloud offers a free account with instant metering capabilities. See the comparison guide for differences with the self‑hosted version.
OpenMeter stores aggregated usage data in ClickHouse and processes incoming events through Kafka.
OpenMeter includes built‑in limit enforcement and can trigger alerts when consumption exceeds defined thresholds.
OpenMeter is released under the Apache‑2.0 open source license.
