# What is an Application

An Application in Frappe is just a standard Python application. You can structure a Frappe Application the same way you structure a standard Python Application. For deployment, Frappe uses the standard Python Setuptools, so you can easily port and install the application on any machine.

Frappe Framework provides a WSGI interface and for development you can use the built-in Werkzeug server. For implementing in production, we recommend using nginx and gunicorn.

Frappe also has a multi-tenant architecture, grounds up. This means that you can run multiple "sites" in your setup, each could be serving a different set of applications and users. The database for each site is separate.
