Free Online Markdown Editor with Live Preview

I needed a clean, fast markdown editor that just works in the browser. No signup, no electron app, no extensions.

So I built one.

Try It

markdownedit-silk.vercel.app

Features

• Split-pane editor: write on the left, preview on the right
• Real-time preview as you type
• Full markdown support: headers, bold, italic, links, images, code blocks, tables, blockquotes
• Copy as Markdown or HTML
• Download as .md or .html file
• Word/character/line count
• Dark theme (easy on the eyes)
• XSS-safe (DOMPurify sanitization)

Why Another Markdown Editor?

Most online editors are either:

• Bloated with features you don't need
• Require signup
• Have bad rendering

This one is zero-friction. Open the URL. Start typing. Done.

Tech

• Next.js 15
• marked.js for parsing
• DOMPurify for XSS protection
• Tailwind CSS
• 100% client-side (no server needed)
