So, here’s something that I didn’t expect to be saying in 2026: There seems to be a nonzero chance that Markdown might become the new RSS.
“Whoa, crazy talk! It’s not even a protocol!” I hear you saying. But the evidence has seemed to pick up of late in a couple of different directions.
The first is the budding interest in publishing on the AT Protocol, which is working to solve the network-effect challenges that have forced many of us to send newsletters rather than post blogs on RSS feeds.
That’s exciting, if incredibly niche. But simultaneously, massive developer platforms are starting to offer something called “Markdown for Agents”—something Cloudflare announced late last week, and which Laravel Cloud quickly followed up on a few days later. And Vercel jumped on it a couple of weeks ago.
(The news wasn’t all good for Markdown, but most of it was.)
Some SEO old hands, like my friend Jon Henshaw, have reacted to this news with skepticism, having had bad old memories of Google AMP and its sibling technologies Signed Exchanges and Core Web Vitals:
It’s 2026, and now I’m reading everywhere that all our pages must have Markdown versions, and it feels like AMP (and SXG and CWV) all over again. Except this time, the promise is that AI agents will better understand and interact with your site if you have them. The rationale is that HTML is too complex and consumes too many tokens to parse and analyze content. Whereas Markdown pages, with their simplicity, are ideal.
(Side note: Core Web Vitals make me want to pull my hair out.)
Jon is a smart guy and follows this stuff closer than me (Coywolf News is a great site), but I will casually defend this push towards Markdown as a lingua franca of the Web. (Not the agentic Web. Just the Web. More on that later.) I actually think it’s really a great move for publishers that comes with way fewer inherent issues than Google AMP ever did.
For one thing, this is all standards-based, not something that was just invented that you need to manage. It’s literally using existing content negotiation headers that web servers already support, not forcing folks to learn something new. Plus it’s hard to argue with a point like this from Vercel:
A typical blog post weighs 500KB with all the HTML, CSS, and JavaScript. However, the same content as Markdown is only 2KB. That’s a 99.6% reduction in payload size.
That’s good for budget-minded AI agents, but it’s also good for people who run websites.
Additionally, Markdown has been in increasingly wide use for 20 years, and it keeps growing in popularity—and unlike the weird carousels and oddly specific rules of Google AMP, lots of people know how to use it. And the use of headers to deliver Markdown pages is already baked into Web standards, just waiting for folks to use it.
