Open Source Rails Tools
Tools for developers
who ship alone
Generators, UI components, and AI tools extracted from production Rails applications. No build pipelines. No framework fatigue. Built for the one-person framework philosophy.
Production-tested Rails tools
UI Library
Maquina Components
Modern UI components for Ruby on Rails. ERB partials styled with Tailwind CSS 4.0 and Stimulus controllers. Inspired by shadcn/ui, built for the Rails way.
AI Tools
Rails Claude Code
A marketplace of Claude Code plugins for Rails — code simplification, Rails upgrades, UI standards, MVP planning, Stimulus best practices, spec-driven development, security audits, and a Hotwire dev-server driver.
App Scaffolding
Maquina Generators
Rails generators that produce standalone application code. Authentication, job queues, error tracking, and security — no runtime dependency. Generate once, own forever.
Engine
Maquina Newsletters
A mountable Rails 8 engine for drafting, approving, scheduling, and batch-sending HTML newsletters. Action Text editing, an approval workflow, and background batch delivery.
Practical tools, not perfect abstractions
Every tool here earned its place in a shipping Rails app before it earned a name. No theory, no lock-in — patterns simple enough to own outright.
- Production first
- Every tool starts in a real application. No theoretical exercises, no “what if” features. If it's here, it's been shipped.
- Standard Rails
- ERB partials, Tailwind CSS, Stimulus only where needed. No new paradigms to learn — the Rails way, refined.
- One-person scale
- Built for developers who ship alone. Simple enough to understand, powerful enough to build real applications.
What we're building
Turn a feature into a shipped pull request — on a new Rails app or one you already have. Durable context, disciplined workflow, full observability from brief to branch.
Your host. Your keys. Your repo. Tokens bill straight to your Anthropic account — never proxied, never marked up.
A dedicated knowledge base for managing the context your AI tools consume. Curate project knowledge once, serve it to every tool via REST API.
Works with Claude Code, Cursor, ChatGPT, and any tool that makes HTTP requests.
Know your daily vibe, spend without the spiral. Resto tells you exactly what you can spend today — no more "can I afford this?" anxiety. Kakeibo-inspired personal finance, simplified.
Track checking accounts, credit cards, and buffers. Reflect on your spending. Plan ahead. All in one place.
