Share a local HTML or Markdown file as one link that updates every time you save

MunchFile watches a .html or .md file on your machine and gives you a URL for it. The URL stays the same while you edit — every time you save the file, the page updates to match. Share the link once; keep editing the file.

How it works

1. 01

   Point MunchFile at the file

   Watch a Markdown or HTML file that lives on your disk. MunchFile reads it locally — there is no upload step you manage and no copy to keep in sync.

   munchfile watch ./status.html

   copy
2. 02

   Get one stable link

   You get a live URL back. The link is tied to the file, not to a single snapshot, so it stays valid as the file changes.

   ✅ Live: https://view.munchfile.com/x7k2p9

   copy
3. 03

   Save to publish

   Edit the file in your normal editor and save. MunchFile detects the change and serves the new version at the same URL. Nobody needs a new link.

Three ways to share

Same file, same live link — pick whichever fits how you work.

• CLI. munchfile watch ./file.html from a terminal, a script, or a server. Full walkthrough in the getting-started guide.
• Mac desktop app. Select a file in Finder and press ⌘⇧M, or use the Services → Copy MunchFile link right-click menu. The link lands on your clipboard. Download for Mac →
• Claude Code. Add the MunchFile MCP server and ask the agent to share a file it just wrote. See the Claude Code workflow.

Why one link instead of a fresh file each time

An attached file is a snapshot — the moment you send it, it starts going stale, and the next revision means a new attachment and a new round of "which version is current?" A MunchFile link renders the file as it is right now, so there's one address to share and one source of truth. No re-attaching, no pile of preview tabs, no deploy step.

HTML specifics

Your HTML is served as a real page inside a sandboxed iframe — your <style> and <script> are preserved. See HTML support for exactly what's kept. If you'd rather write <div class="card"> than inline styles, HTML files can opt into hosted Tailwind + DaisyUI with one meta tag — that's Style Embeds.
