Fast, secure websites that search engines and AI actually understand.
Publii builds static websites locally on your computer, then sends them straight to your server. No database queries. No external requests. Just instant delivery. This matters more now than it used to — AI models like ChatGPT, Perplexity, and Google SGE analyze structure and meaning to answer questions directly. If your site is slow or messy, you're invisible.
Speed is just the start. Publii generates clean semantic HTML5, readable URLs, structured metadata, Open Graph tags, and XML sitemaps by default. Your site becomes easy to index and interpret — for both search engines and AI crawlers. Minimal JavaScript. No frameworks. No bloat.
What does that actually mean? Your content ranks better. AI systems can parse it without guessing. Crawlers don't get stuck. And users get pages that load before they finish blinking.
The web is changing. Search results now pull from AI summaries. If your site isn't structured for machine understanding, you're losing traffic. Publii builds that structure in from day one.
