One of the biggest time sinks in early-stage product development is making the same design decisions over and over. What color should this button be? How much padding goes inside a card? Should this text be 14px or 16px?
A design system answers all these questions once, permanently.
What Is a Design System?
A design system is a collection of reusable components, guided by clear standards, that can be assembled to build any number of applications. At its simplest, it's a set of CSS classes and React components that cover every common UI pattern your app needs.
Why Build One Early?
Solo founders often resist this, thinking it's an enterprise concern. It isn't. Even a minimal design system — a consistent color palette, 3 button variants, a card component, and a form input style — can cut your UI development time in half.
The POM6 Approach
Here's the minimal design system we recommend for indie SaaS products:
Colors
Typography
Components
Spacing
Stick to Tailwind's spacing scale (4px base unit). Never use arbitrary values.
Implementation
Using Tailwind CSS, you can define these in your 'globals.css' with '@layer components'. Every new page you build will automatically look consistent, and you'll never agonize over button colors again.
The time investment to set up a basic design system: 2-4 hours. The time it saves over a 6-month build: 40-100 hours.
