## Quick Start

The fastest way to set up your agent with LangWatch and get started is by using LangWatch Skills via a coding assistant. If your agent is already set up, check out the skills to monitor performance and improve your agent.

## What is LangWatch?

LangWatch is the **open-source** LLMOps platform that helps teams collaboratively debug, analyze, and iterate on their LLM applications. All platform features are natively integrated to accelerate the development workflow.

Building AI applications is hard. Developers spend weeks debugging issues, optimizing prompts, and ensuring quality. Without proper observability, you're flying blind - you don't know why your AI behaves the way it does, where it fails, or how to improve it.

LangWatch provides the missing operations platform for AI applications. Every LLM call, tool usage, and user interaction is automatically tracked with detailed traces, spans, and metadata. See the full conversation flow, identify bottlenecks, and understand exactly how your AI applications behave in production.
