ScaffoldHub / Compare / Bullet Train
ScaffoldHub vs Bullet Train
Bullet Train is a Rails-based SaaS boilerplate. Notably it ships super_scaffolding — a CLI that generates Rails models, controllers, views, and tests for new entities. In that sense, both Bullet Train and ScaffoldHub are generators, not pure fork-and-fix kits.
The split is language and surface area. Bullet Train generates Rails code; ScaffoldHub generates TypeScript across React, Hono, Prisma, and a mobile scaffold. Bullet Train invokes generation per entity from the CLI; ScaffoldHub maintains the full data model on a visual canvas and regenerates the whole project from it.
If your team is Rails, Bullet Train is the right choice. If your team is TypeScript and you want one model that drives web, API, and mobile, ScaffoldHub fits.

When to pick Bullet Train
- You're a Rails team.
- You're comfortable in the Ruby ecosystem.
- You want a free open-source baseline.
When to pick ScaffoldHub
- You're a TypeScript team.
- You want a visual data-model canvas instead of a CLI.
- You want the generated code optimized for AI coding assistants.
- You want a mobile scaffold included.
What you get with ScaffoldHub
ScaffoldHub generates a production-ready full-stack TypeScript project from a visual data model — Prisma schema, Hono API, React + TanStack forms and lists, validation, RBAC, audit logs, i18n, Stripe billing, and an Expo mobile scaffold. Every project ships AGENTS.md, a docs/ folder, and a built-in MCP server so AI coding assistants can extend the code without re-prompting.
Frequently asked questions
Both ScaffoldHub and Bullet Train use scaffolding — what is the real difference?
Bullet Train scaffolds entities one at a time via a Rails CLI. ScaffoldHub maintains the entire schema as a visual model and regenerates the whole project from it. The first is incremental and CLI-driven; the second is whole-project and model-driven.
Is Bullet Train free?
There is a free open-source baseline. Paid tiers add features and support.
Can I use Bullet Train with TypeScript?
No, Bullet Train is Rails. ScaffoldHub is the TypeScript-side equivalent if you want a generator approach but in a JavaScript ecosystem.
