About

Buio — Web3 theme for Astro & Tailwind CSS

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
CMS optional — includes a .pages.yaml that reads your Astro content collections. No plugins, no edits to your code.
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 — lifetime value
