High-performance usage-based billing engine designed for AI token metering and credit management.
OpenBilling is a cloud-native, high-concurrency billing engine architected to solve the complexities of 2026's usage-dominant economy. Unlike legacy subscription platforms, OpenBilling focuses on real-time event ingestion, making it the preferred choice for AI companies needing to meter LLM token consumption, API calls, and GPU compute hours. Its technical architecture utilizes a distributed event bus to handle millions of metering events per second with guaranteed idempotency, ensuring that no billable event is lost or double-counted. In the 2026 market, OpenBilling sits as a critical piece of the 'AI Stack,' allowing developers to decouple their billing logic from their core application code. It supports complex pricing models including tiered usage, prepaid credit ledgers, and hybrid 'platform fee + usage' structures. By offering a self-hosted open-source core alongside a managed cloud offering, it provides the data sovereignty required by enterprise-grade AI applications while maintaining the agility of a developer-first platform. It integrates natively with tax automation engines and global payment gateways, bridging the gap between raw infrastructure usage and compliant financial reporting.
