# Utilities

The Utilities section provides developers with detailed information and guidance on developing with NDI utilities to expand the potential of NDI workflows. Here, you'll find resources for **NDI Bridge Service**, **NDI Free Audio**, and **NDI Unreal Engine**. These utilities are designed to empower developers to build, customize, and enhance NDI-enabled solutions efficiently.

**NDI Utilities** are standalone applications designed for specific purposes within NDI-based workflows or for integrating our technology into products. Unlike the NDI Tools, which feature a closed user interface, these Utilities are meant for more flexible uses and exploration. Some of them may only be operated through a command-line terminal.
