# Installation

## Components

Devin consists of two primary components.

### Devin App

This is a `fmp12` file that gets installed locally on your **workstation**. Developers access Devin's features through this app.

### Devin Server

Running on your servers, it comprises the **Devin Engine** and various **Devin APIs**. This backend executes the operations initiated from the **Devin App**. There are two key server roles:

* **Development Server**: Hosts all development files and includes the Devin Engine (`devin-engine.fmp12`) which is automatically installed for Development server types.
* **Non-Development Server**: These servers hosts your `fmp12` files in various non-dev environments, such as staging, Q/A, or production.

{% hint style="info" %}
The Devin App does not store any project data. Developers can easily collaborate on projects because each Devin App connects to the shared `devin-engine.fmp12` database, located on your development server.
