Markdown to HTML

Export Markdown to clean HTML — fragment, styled, or full document. Zero dependencies. Powered by CapabilityBase Runtime.

💡 Why this exists

AI agents generate Markdown. APIs consume HTML. Existing solutions are either heavy (hundreds of KB) or unsafe (XSS vulnerabilities). This Capability gives you a zero-dependency, XSS-safe Markdown-to-HTML exporter with three output modes — for embedding, styling, or saving as standalone documents.

Frequently Asked Questions

Can I export a full HTML document?

Is it useful for email templates?
