# Overview

> Explore xApp build tutorials: standalone xApps, multi-channel xApps, and custom xApp Node development.

To build xApps, use these tutorials:

* [Build your First xApp](/xApps/build/first-xApp)
* [Build an xApp with Multiple Channels](/xApps/build/xApp-with-multi-channels)
* [Build a Standalone xApp](/xApps/build/standalone-xApp)

Additionally, you can create your own [customized Node](/xApps/build/custom-xApp-node).

## Examples

You can find ready-made examples of xApps in the [Cognigy GitHub](https://github.com/Cognigy/xApps/tree/main) repository.

## Security

When building an xApp, it's important to mitigate the risk of an XSS attack. Check out our recommendations in the [xApps Security](/xApps/security/secure-xApp-from-xss) section.
