Bullet Train is an open-source Ruby on Rails application template for building SaaS products. It provides a batteries-included starting point with authentication, teams, billing, and common SaaS scaffolding.

Use cases

• build a saas product with rails
• rails starter template with authentication and billing
• kickstart a multi-tenant ruby on rails app
• bootstrap a subscription web application
• create a new rails app with teams and user management

When to choose

• you are starting a new Ruby on Rails SaaS application from scratch
• you want prebuilt authentication, teams, and billing scaffolding
• you prefer convention-driven Rails development with a curated stack

When to avoid

• you are maintaining an existing Rails app that cannot adopt the template structure
• you need a framework outside Ruby or Rails
• you want a minimal, unopinionated starting point
