Building a Design System That Actually Scales

Most design systems die in the Figma file phase. We've shipped five this year. Here's the structural decisions that separate the ones teams love from the ones teams abandon.

Stop building everything from scratch

In 2026, building your own basic primitive components (Buttons, Modals, Dropdowns) is a waste of engineering time. We start every design system with headless UI libraries like Radix UI or React Aria, and style them with Tailwind CSS.

The 3-Tier Architecture

1. Design Tokens: Raw values (colors, spacing, typography) defined in a central config.
2. Primitives: The basic building blocks (Button, Input). They contain zero business logic.
3. Compositions: Complex, domain-specific modules (UserAvatarCard, SubscriptionTable).

When design systems fail, it's usually because developers mix Tier 2 and Tier 3, creating bloated primitives that are impossible to reuse in different contexts.
