How to Build a Scalable UI Component Library Without a Framework (2025 Guide)

Most teams jump straight into React, Vue, or Tailwind when building components — but you don’t need a framework to create a scalable UI library. In 2025, native web features like Custom Properties, Web Components, and modern CSS architecture make it completely possible.

I just published a full guide on building a framework-agnostic, scalable component library that works anywhere.

🧩 What the guide covers

  • Why “no-framework” component libraries are trending
  • Structuring components using BEM and modern CSS
  • Using CSS Variables for theming
  • When Web Components make sense
  • Reusable patterns for buttons, modals, forms, tooltips
  • Accessibility rules for cross-framework components
  • How to scale, document, and maintain your UI kit
  • Practical examples & real-world tips

If you want to build a design system that works in any stack — React, Vue, Svelte, static HTML — this guide walks you through the entire process.
