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.
Featured Product
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.
Featured Product
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.
Open Source
Production-tested tools
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.
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 Integration
Rails MCP Server
A Model Context Protocol server that lets LLMs interact with Rails projects. Analyze models, routes, schemas, and execute read-only Ruby code in your Rails context.
Claude Skill
Rails Simplifier
A Claude Code skill for simplifying and refining Ruby on Rails code. Follows 37signals patterns and One Person Framework philosophy.
Philosophy
Practical tools, not perfect abstractions
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.
