About Buio. What it is and how it works.

Buio is a dark SaaS theme for Web3 products, built with Astro and Tailwind CSS. Sharp layouts, clean typography.

Buio: the dark Web3 template with an edge

Buio is a dark, minimal Web3 theme built for teams that work on blockchain, developer tools, and next-gen products.
Its design is focused, high-contrast, and reliable: giving complex products the clarity they need to be understood instantly.

Why Buio

  • Designed for Web3 startups, SaaS platforms, and developer tools
  • Astro-fast: built for performance, accessibility, and SEO
  • Tailwind-flexible: consistent, modular, and easy to extend
  • Includes multiple landing and pricing layouts, plus status and contact pages
  • Content collections for blogs, teams, customers, and changelogs
  • SEO-ready with Astro SEO, Sitemap, and RSS integrations
  • AOS animations for subtle motion where needed
  • Clean file structure with reusable components and ongoing updates

Layout & Structure

Buio uses darkness as structure, not decoration.
It blends glow accents and precise spacing to create a strong, technical aesthetic without losing calm or readability.
Typography is restrained. UI elements feel measured and deliberate.

One-time license: built for the long run

Buy once. Use forever. Launch your next product with precision and presence.
