Flexprice provides an open-source metering and billing layer for AI, API, and SaaS products. Teams can send product-usage events, define meters and pricing rules, and convert measured activity into customer-facing usage and billing data. The project is licensed under AGPL-3.0 and can be deployed in your own environment or used through Flexprice's managed offering.
For AI products, Flexprice can model token, request, credit, or feature consumption without forcing the application to implement billing logic in every service. Its product surface covers real-time metering, usage-based price models, prepaid credits and top-ups, entitlements, and customer usage visibility. That makes it relevant when engineering, product, and finance need a shared record of billable consumption rather than another LLM trace viewer.
Choose Flexprice when flexible pricing and billing operations are the main requirement and self-hosting matters. Evaluate the event model, invoice and payment integrations, tenancy controls, data-retention needs, and AGPL obligations against your architecture before rollout. Treat it as commercial metering infrastructure: observability platforms may explain model behavior, while Flexprice is intended to turn approved usage into limits, credits, and billing workflows.
