7 SaaS kits compared with Bullet Train on price, license, framework and features.

About Bullet Train

Bullet Train (Ruby on Rails, free) - An MIT-licensed Rails SaaS framework with team management, billing, and API scaffolding built in. Best for: Rails developers who want a mature, MIT-licensed SaaS framework with multi-tenant teams, billing, and API generation instead of assembling gems themselves.

The usual reason to look elsewhere: you're not building on Ruby on Rails, or you want a lighter-weight starter without Bullet Train's opinionated Super Scaffolding conventions.
