# Open Source at Narev

> Discover Narev's open-source initiatives for AI billing and infrastructure cost mapping.

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`](https://github.com/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

## [`narevai/narev`](https://github.com/narevai/thin-ops)

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.
