Overview

Helio is a production-ready help center and documentation template that transforms how you deliver customer support. Built specifically for startups, SaaS companies, and developers, this modern template eliminates months of development time while delivering a professional support experience that rivals enterprise solutions.

Powered by Astro's cutting-edge architecture, Helio generates lightning-fast static HTML that achieves near-perfect Lighthouse scores out of the box. Your help center will load instantly, cost virtually nothing to host on platforms like Cloudflare Pages or Vercel, and provide an exceptional user experience that keeps customers engaged and reduces support tickets.

Complete customization takes minutes, not weeks. Every visual element—from colors and typography to navigation and branding—is controlled through a single configuration file, allowing you to rebrand the entire site in under five minutes to perfectly match your product's identity.
