# Introduction

> The fast lane to production AI. Gateway, SDK, and observability for LLM-powered applications.

Muxx is an AI gateway and observability platform that sits between your application and LLM providers. It logs every request, tracks costs, measures latency, and provides a dashboard to understand your AI usage.

## Why Muxx?

Building AI-powered applications is exciting, but running them in production is challenging:

* **Cost visibility** - LLM API costs can spiral quickly. Muxx tracks every token and dollar.
* **Debugging** - When something goes wrong, you need to see the full request/response. Muxx logs everything.
* **Performance** - Response caching reduces latency and costs for repeated queries.
* **Reliability** - Rate limiting and spend caps protect your budget and prevent abuse.

## Three Integration Modes

Muxx offers flexibility in how you integrate:
