## FAQ

### What formats can I publish?

You can publish interactive HTML applications, GitHub-flavored Markdown, responsive Mermaid diagrams, and raw vector SVG graphics.

### How secure is the artifact rendering?

The server uses a zero-trust security sandbox where untrusted artifacts render inside isolated iframe containers with strict Content Security Policy.
