What is Bullet Train

Bullet Train is an open-source Ruby on Rails framework and SaaS application template. It gives developers a working foundation for multi-tenant SaaS products with authentication, teams, roles, permissions, billing, APIs, webhooks, integrations, admin tools, and deployment support.

Overview

Bullet Train is built for developers who want to build a SaaS product on Rails without implementing the same application infrastructure from scratch. It provides account and team management, authentication, roles and permissions, onboarding, REST APIs, incoming and outgoing webhooks, Stripe billing, background jobs, an admin panel, testing tools, and a component-based UI system. The project is open source and uses Ruby on Rails with PostgreSQL and Redis. Its scaffolding system can generate application code and database structures as your product grows, making it more useful for a full SaaS application than a basic Rails starter.

Who should and shouldn't use it

Should use it

  • You need multi-tenant accounts, teams, roles, and permissions

  • You want scaffolding tools that can generate common SaaS application code
Shouldn't use it
  • You are building with Next.js, Laravel, Django, or another non-Rails stack
  • You want a minimal Rails starter with very little pre-built functionality
