# 👋 Welcome to Baserun

**[Baserun](https://baserun.ai)** helps AI teams build, monitor and iterate their LLM applications.

At a high level, the LLM application development lifecycle can be broken down into three phases: **build**, **monitor**, and **improve**. Each phase has its unique challenges, as shown in the following image:

Baserun provides a suite of tools, accessible through both UI and SDK, for AI teams
to collaborate throughout the product development cycle.

Here is the guide on how to navigate different features within Baserun:
