# What is a Node

Nodes are the building blocks of your workflows in Scade.pro. Think of them as tiny but mighty units that represent various functions, from AI and blocks of code to logical functions. By connecting these nodes, you can create customized workflows tailored to your specific needs. Let's break down the essentials of working with nodes.

Each node comes with real-time operational feedback through color-coded indicators:

* Blue: The node you're currently working on.
* Green: Nodes that have completed their tasks.
* Gray with a Dash Pattern: Nodes currently in operation.
* Red: Nodes encountering an error.

Nodes also display execution time and the cost of launching, allowing you to assess the efficiency and expenses associated with each node.
