Kind: Content-first web framework · License: Open source · Last verified: 2026-10-12

Renders content pages to static HTML by default, with optional interactive islands and adapter-based request-time rendering. Content collections load local or remote content and validate its schema.

Reach for it when:
- Blogs, docs, and marketing sites
- Sites that need near-zero JavaScript
- Mixing React, Vue, or Svelte components on one page

Worth knowing: Request-time rendering needs a compatible adapter; a static build cannot personalize each request. The framework's license is MIT with notices for included code; hosting terms are separate.
