It’s built with: ✅ Next.js – for server-side rendering and app-level routing ✅ TypeScript – for type safety and scalability ✅ Tailwind CSS – for rapid styling and full customization ✅ Framer Motion – for sleek, production-ready animations

For developers building SaaS platforms, dashboards, landing pages, or e-commerce apps, Spectrum UI is a time-saverthat combines great design with developer-friendly code.

At Start Matter, we’re already exploring ways to integrate it into our client projects.

💎 Why Developers Love Spectrum UI

📦 1. Massive Component Library

With over 250 components and full-page layouts, you get prebuilt UI blocks for:

• Login & signup pages

• Dashboards with charts & widgets

• AI chat interfaces

• Multi-step forms & payment flows

These are production-ready, responsive, and accessible by default (thanks to shadcn/ui and Radix UI).

⚡ 2. Fast Integration

Spectrum UI makes it easy to drop components into your app:

• Copy-paste code snippets directly from ui.spectrumhq.in

• Or use the Spectrum CLI for a faster workflow

This approach fits perfectly for teams using React + Tailwind CSS.

🎨 3. Built for Customization

Tailwind makes it easy to tweak styles, while TypeScript ensures robust, type-safe usage. You own the code - there’s no vendor lock-in.
