mdbin is a place to share Markdown. Paste a document, get a clean link, and send it to anyone — your notes, a README, a proposal, or a design doc render as a proper page instead of a wall of plain text. mdbin is built and run by forjed.io.

What makes it more than a plain pastebin is live rendering: fenced code is syntax-highlighted, and fenced diagrams are drawn for real — both Mermaid and hand-drawn FreeDraw flowcharts.

Create and share#

Hit New, write (or paste) Markdown, and submit. You get a short, stable URL you can share or bookmark. Every document also has a plain-text Raw view for copying the original source.

What renders#

mdbin understands standard Markdown — headings, lists, tables, blockquotes, links, and images — plus three things worth their own guides:

• Code blocks — fenced code with automatic syntax highlighting.
• Mermaid diagrams — flowcharts, sequence diagrams, and more, from text.
• FreeDraw diagrams — flowcharts with a hand-drawn look.

Comments, forking, and expiry#

Readers can leave line-level comments anchored to a specific block, so feedback lands exactly where it belongs. You can fork any document to start your own copy, and documents can be set to expire so they don't live forever.

Privacy and safety#

Markdown is rendered safely: raw HTML is disabled, links are restricted to safe protocols and hardened with rel="nofollow noopener noreferrer", and the output is sanitized before it ever reaches the page. You can write freely without worrying about scripts running in someone else's browser.
