Markdown
Preview
BeautMD is a single HTML file served from a CDN. There is no application server, no database, and no analytics endpoint operated by us. Once the page loads, every feature runs locally in your browser.
The markdown you type is kept in your browser's localStorage so your
work survives a refresh. That storage lives on your device and is never transmitted
to us.
The Share button encodes your document into the fragment portion of the
URL — everything after the #. Browsers never transmit URL fragments
to any server, so the content travels only with the link you choose to send.
Whoever has the link has the content; whoever doesn't, doesn't.
The page loads a few open-source libraries from public CDNs (marked, DOMPurify, highlight.js, mermaid, MathJax, pako). Those CDNs see your IP address like any other web request, but they receive no part of your document.
No cookies, no analytics, no accounts, no sign-in.
