Configuration Overview

Arcade uses configuration files to manage engine settings and default values. When you install the Arcade Engine, two files are created:

• The engine.yaml file for engine configuration.
• The engine.env file for environment variables.

Let’s explore each file to understand their purpose and how to locate them.

Engine configuration file

The engine.yaml file controls Arcade Engine settings and manages supported models. It supports variable expansion so you can integrate secrets and environment values seamlessly. You can customize this file to suit your setup. For more details, check the Engine Configuration page.

Choose your installation method to view the default location of engine.yaml:

$HOMEBREW_REPOSITORY/etc/arcade-engine/engine.yaml

/etc/arcade-ai/engine.yaml

$HOME/.arcade/engine.yaml

Engine environment file

The engine.env file contains default environment variables that power Arcade Engine. You can override these defaults by exporting your own variables or by editing the file directly.

Select your installation method below to see the default path for engine.env:

$HOMEBREW_REPOSITORY/etc/arcade-engine/engine.env

/etc/arcade-ai/engine.env

$HOME/.arcade/engine.env
