The missing design process between your idea and your codebase
Design OS is a product planning and design tool that helps you define your product vision, sketch out your data shape, design your UI, and export production-ready components for implementation. Rather than jumping straight into code, you work through a guided process that captures what you’re building and why—then hands off everything your coding agent needs to build it right.The Problem
AI coding tools are incredible at building fast. But the results often miss the mark. You describe what you want, the agent builds something, but it’s not what you envisioned. The UI looks generic. Features get half-implemented. You spend as much time fixing and redirecting as you would have spent building. The core issue: we’re asking coding agents to figure out what to build and build it simultaneously. Design decisions get made on the fly, buried in code, impossible to adjust without starting over. There’s no spec. No shared understanding. No source of truth for what “done” looks like.The Design OS Process
Design OS powers a guided design and architecture process. You + AI, working together through structured steps:Section Design
For each feature area: specify requirements, generate sample data, and design the screens
Quick Start
Getting Started
Learn the basics and start designing your first project
Installation
Set up Design OS on your local machine
Product Planning
Define your vision, roadmap, and data shape
Design Sections
Create screen designs for each feature area
How It Works
Design OS is its own separate codebase—a design environment you use before building. When you’re done, you export components and assets to import into your actual product’s codebase. You interact with Design OS through slash commands. Each command walks you through a specific part of the process:/product-vision— Define your product, break it into sections, and sketch the data shape — all in one flow/design-tokens— Choose your color palette and typography/design-shell— Design navigation and layout/shape-section— Define a section’s scope, requirements, and generate sample data + types/design-screen— Create production-ready React components/export-product— Generate the complete handoff package
Design OS is free, open source, and runs locally on your machine.
Who It’s For
Technical Builders
Full control over architecture and design decisions without doing all the legwork yourself
Non-Technical Builders
A strong vision for how your product should work, plus the ability to put your imprint on its systems—no technical background required
