Open Source at Narev

At Narev, we invest heavily in open source to build the right foundation for the AI ecosystem. Our open-source projects are designed to solve the hardest parts of AI FinOps, from usage-based billing to infrastructure cost visibility.

​

narevai/ai-billing

We created @ai-billing to make usage-based billing easy for AI applications. It’s a suite of middleware and integrations that handles the complex mechanics of usage-based billing:

• Capturing token usage across different providers
• Resolving live model prices
• Routing structured billing events to payment platforms

For teams that need raw visibility into their infrastructure costs without the full billing engine, we offer Narev Self-Hosted. This open-source container maps your infrastructure layer costs (COGS) and provides a clear view of your AI spend. While Narev Cloud remains our primary platform for end-to-end FinOps and billing, the self-hosted deployment provides a straightforward way to start tracking your costs in the FOCUS format.
