Bullet Train is an open source Ruby on Rails framework that provides a starter template for building Software as a Service (SaaS) applications.

It includes features such as user authentication, roles and permissions, teams and invitations, a REST API, and more.

The goal of the framework is to save developers time by providing common functionality so they can focus on what makes their application unique.

Bullet Train is developed and maintained by Bullet Train, Inc. and is available on GitHub under an MIT licence.
