Where to Find Markdown on the Web

A guide to feeds, sites and directories that serve Markdown directly, plus search tricks for finding more.

Compiled November 5, 2026. Everything here was found through web search; the links were not fetched one by one, so test before you rely on them.

1. The four ways the web serves Markdown

2. RSS feeds with <source:markdown>

source:markdown is an element from Dave Winer's Source namespace for RSS. A reader that can render Markdown can use it in place of the item's <description>. The namespace is declared at the top of the feed:

<rss version="2.0" xmlns:source="https://source.scripting.com/">
  ...
  <item>
    <description>&lt;p&gt;Watching &lt;a href="..."&gt;Edge of Tomorrow&lt;/a&gt;&lt;/p&gt;</description>
    <source:markdown>Watching [Edge of Tomorrow](https://www.themoviedb.org/movie/137113)</source:markdown>
  </item>

Related namespaces

• now:markdown – from Colin Walker's Now namespace, for sharing /now-page updates in Markdown. Works the same way as source:markdown. Spec
• derived:code – from Rubenerd's derived namespace. Links to a post's original Markdown source file instead of embedding it: <derived:code type="text/markdown" url="..."/>. Spec

3. Feed readers and tools that understand Markdown in RSS

4. Sites with .md versions of their pages

Add .md to a page URL (or follow the "Markdown" link on the page).

5. Sites that answer Accept: text/markdown

Same URL as the web page; ask for Markdown in the request header:

curl -H "Accept: text/markdown" https://blog.cloudflare.com/markdown-for-agents/

6. Platforms that make every site Markdown-ready

If a site is built on one of these platforms, its pages are probably available as Markdown even if the site doesn't advertise it.

7. llms.txt directories

An llms.txt file is itself Markdown: an H1 with the site name, a blockquote summary, then H2 sections of links. Good llms.txt files link straight to .md pages. These directories list sites that have one:

Google

Google's own documentation says filetype: matches either the HTTP Content-Type header or the file extension, so in principle it can find files served as text/markdown. In practice filetype: has been unreliable since 2024 and works best combined with site: or inurl:. These queries are worth trying (not yet tested):

filetype:md site:github.com <topic>
filetype:md -site:github.com <topic>        # the "-site:" trick re-enables filetype:
inurl:llms.txt <topic>
inurl:"llms-full.txt"
inurl:sitemap.md
"source:markdown" inurl:rss
"source:markdown" inurl:feed
"xmlns:source" "source.scripting.com"

GitHub code search (needs a GitHub login)

"source:markdown" path:*.xml              # feeds committed to repos
"xmlns:source" path:*.xml
"rel=\"alternate\" type=\"text/markdown\""  # pages advertising a Markdown twin
filename:llms.txt

Discovery tags to look for in a page's HTML

<link rel="alternate" type="text/markdown" href="/page.md">
<atom:link href="/feed/markdown/" rel="alternate" type="text/markdown"/>

9. Checkers and test commands

Check whether a URL serves Markdown:

# Content negotiation
curl -sI -H "Accept: text/markdown" https://vercel.com/docs | grep -i content-type

# .md suffix
curl -sI https://docs.stripe.com/stripe-apps/pkce-oauth-flow.md | grep -i content-type

# Does a feed include source:markdown?
curl -s https://www.manton.org/feed.xml | grep -c "<source:markdown>"
