# Custom Apps

## Overview

### Context

You will learn how to set up your environment to create a custom app and the tools to interact with the desk using NextJS.

A complete breakdown of our guidelines for Conversation Panel Apps can be found in [our knowledge base](https://help.iadvize.com/hc/en-gb/articles/4404351307026-Conversation-Panel-Apps-Guidelines).

Please note that one iframe is created per conversation in order to keep a context for an app for each conversation. It is recommended to keep the app very lightweight and avoid heavy processing or streaming updates.
