Built for App Engine

Created specifically for Google’s cloud, Ferris embraces the underlying platform and puts the power of App Engine at your fingertips. Ferris is built on top of Cloud Datastore and the native Webapp2 framework and is integrated with multiple App Engine services, including search and protorpc.

The framework also provides utilities for OAuth2, making it easy to authenticate and use Google's APIs. When you absolutely need to, it's easy to get Ferris out of your way and access App Engine services directly.

Rapid Development

Ferris is a familiar MVC framework inspired by Rails, CakePHP and Flask that allows you to get up and running in seconds and build using conventions instead of unnecessary configuration.

We've also thrown in a fantastic, customizable and dynamic scaffold to help you create CRUD applications in seconds. Scaffold doesn't do what you want? Easily configure, replace, or augment individual actions or templates without having to give up the entire scaffold.
