HTMLy is a website publishing and hosting service for static HTML projects, including pages created with ChatGPT, Claude, and other AI tools. Users can upload files, paste code, or submit a ZIP archive and publish a site within seconds, without configuring a server or using Git. Each site includes a clean HTMLy subdomain, free HTTPS, and Cloudflare CDN. The platform also provides automatic SEO metadata, Open Graph tags, a sitemap, and server-side analytics designed to comply with Brazil’s LGPD requirements.

HTMLy supports connections to AI assistants through MCP, allowing them to publish and update sites directly. Its free plan includes one site, 10 MB of storage, three updates per day, and no expiry when used with an account; it requires no credit card and displays HTMLy branding. Paid plans offer more sites and storage, additional features, and options such as custom domains and site-wide passwords. Pro customers also receive migration assistance, priority support, automatic backups, and an inline editor.
