About OpenMeter
OpenMeter is a metering and billing tool for products that charge by usage. It collects events from your application and turns them into usage data that can drive invoices, limits and entitlements.
What it does
OpenMeter records usage events from APIs and AI services and aggregates them in real time. Developers can use the data to enforce limits, show customers their usage and produce billing figures. A product catalog covers plans, credits and commitments, so pricing changes can be made without rewriting code.
Key features
- Real-time usage metering from events
- Usage limits, quotas and alerts
- Entitlements for free and paid tiers
- Flexible product catalog for plans and credits
- SDKs for Node.js, Python and Go
Who it's for
OpenMeter is aimed at developers building usage-based products, especially API platforms and AI services. Product and finance teams can use the catalog to change pricing and packaging. Teams with simple flat-rate pricing will probably not need an extra metering layer.
Pricing and good to know
The open source code is published under the MIT license, so you can self-host it. OpenMeter also offers a managed service, which the site describes as available through Kong Konnect. The site links to pricing and a demo request. Self-hosting means your team runs the infrastructure and updates itself.
Highlights
- Meter events in real time from logs and metrics
- Set usage limits, quotas and notifications
- Build plans, credits and usage-based pricing
- Use entitlements to restrict free tiers
