# Markdown negotiation by platform

In short

9.1 percent of crawled home pages answered a markdown request with markdown, but the rate depends on the platform: Framer sites did 93.7 percent of the time and Wix sites 0.0 percent. The page sets the crawl rates beside the rubric scores for 23 platforms and the vendor statements.

A client that sends `Accept: text/markdown` to a page asks for the same content without the page chrome. Whether it gets markdown depends on the platform more than on the site owner: some send it by default, some need a switch, a plan or a plugin, and some cannot. The crawl asked 8,802 home pages that answered 200 and 798 of them (9.1 percent) sent markdown.

## What the crawl found, by platform

Platform comes from the generator meta tag, so only sites that declare one are counted. Framer sites answered with markdown 93.7 percent of the time (179 of 191); Wix 0.0 percent (0 of 29). The generator tag says what built the page, not what serves it, so a rate above a platform's default score means the owner or the host added markdown on top: Astro sites answer 24.5 percent although a default Astro build does not.

Share of home pages that answered the markdown request with markdown, for platforms declared in a generator tag with at least 10 home pages, crawl of 2026-11-04. Solid is markdown, pale with an outline is not markdown.

## What each scored platform does

The platform rubric scores markdown on request: 2 is on by default, 1 needs setup, a plan, a plugin or an extra service, 0 is not offered. The first sentence of each cell's evidence is shown.

| Mintlify | 2 | Accept: text/markdown and Accept: text/plain both return markdown on the page URL. |
| GitBook | 1 | The .md suffix is documented; Accept-header negotiation is not documented on the page read, although gitbook.com answered it. |
| Next.js (App Router defaults) | 1 | Accept: text/markdown returned text/html. |
| Nuxt | 1 | Accept: text/markdown returned text/html. |

## The vendors behind them

The vendors section reads each vendor's own pages for the same behaviour. 7 of 74 state that they answer `Accept: text/markdown` on the same URL.

| Vendor type | Vendors | Supports | Partial or announced | No statement |
| --- | --- | --- | --- | --- |
| Site builders | 8 | 1 | 1 | 6 |
| Content management systems | 7 | 0 | 2 | 5 |
| Docs platforms | 18 | 6 | 2 | 10 |
| Frameworks | 22 | 0 | 4 | 18 |
| Hosts, CDNs and edge products | 12 | 0 | 4 | 8 |
| Markdown and llms.txt tooling | 7 | 0 | 0 | 7 |

## Does it matter

Ora's lab found (2026-10-19) that agents asked for markdown on about 65 percent of fetches, and that markdown mirrors and content negotiation never changed whether they succeeded. Ora's catalogue still scores it: the Markdown agent docs check is emerging tier, and Markdown content negotiation with Vary: Accept, which needs the scanned homepage itself to answer, is recommended tier at 1 point. Ora's passRate for the second reads 99.3 percent and its stricter rate 26.9 percent of 141,709 results (5 November 2026). The [guide to serving markdown on request](https://agentreadyhtml.com/guides/serve-markdown-on-request/) has the rule for each host, and the [viewer](https://agentreadyhtml.com/viewer/) tests one page.
