# Third-party components

> FlowX.AI uses a number of third-party software components

## Overview

FlowX.AI relies on various third-party components to deliver its functionality. These components fall into two categories:

* **Embedded components**: Third-party software packaged and managed by FlowX.AI
* **Client-managed components**: Third-party software that you deploy and maintain

<Info>
  For optimal performance and reliability, our internal QA process validates new releases using specific versions. While you can explore alternative versions that suit your requirements, we recommend referring to the compatibility matrix for guidance.
</Info>

<Note>
  Licensing of third-party components is governed by each vendor and may change over time. Consult each vendor's official licensing documentation for current terms.
</Note>

## Embedded components

<Note>
  Embedded components are shipped and configured as part of the FlowX.AI platform. FlowX.AI manages their versioning, patching, security updates, and provides L4 support coverage. They are deployed alongside the platform using the standard FlowX.AI deployment process.
