# Redocly against Scalar on what an agent reads

In short

Redocly creates an llms.txt for each site that lists pages and links a clean markdown version of each, in the llmstxt.org format. Redocly: On 2026-11-04 redocly.com answered Accept: text/markdown with text/markdown. Redocly leads on content in the initial HTML, 2 to 1; Scalar: Docs pages are served as HTML; the API reference component renders in the browser in some embeds.

## The sourced difference

Scalar Docs always serves llms.txt and llms-full.txt and users cannot author them; Redocly makes the llms.txt title, description and sections configurable under SEO config and lets it be turned off. [Source](https://scalar.com/products/docs/configuration/llms-txt), read 4 November 2026.

## The rubric side by side

| Key | Redocly | Scalar |
| --- | --- | --- |
| Content in the initial HTML | 2, on by default | 1, with setup |
| Real status codes | 2, on by default | 2, on by default |
| llms.txt generation | 2, on by default | 2, on by default |
| llms.txt linking | 1, with setup | 1, with setup |
| Markdown on request | 1, with setup | 1, with setup |
| JSON-LD output | 0, not offered | 0, not offered |
| OpenAPI exposure | 2, on by default | 2, on by default |
| Fenced, tagged code | 2, on by default | 2, on by default |
| Total | 12 of 16 | 11 of 16 |

The two differ on 1 of the numeric keys: content in the initial HTML. Evidence for each score is on the profiles of [Redocly](https://agentreadyhtml.com/platforms/redocly/) and [Scalar](https://agentreadyhtml.com/platforms/scalar/).

## Verdicts by reader

Technical SEO

Scalar output is deterministic per build; Redocly can be tuned.

Docs owner

Pick Redocly if you need to curate the index, Scalar if you want zero settings.

Front-end developer

Both link OpenAPI from the docs; Scalar links the spec file inside llms.txt.

## What each leaves undone

### Redocly

-   Does not document Accept-header negotiation on its AI-ready page.
-   Does not document JSON-LD output for agents.

### Scalar

-   Does not let users author the generated llms.txt on hosted Scalar Docs.
-   Does not include hidden pages.

Work left to the developer: Redocly, Low: configure llms.txt sections under SEO config. Scalar, Low on hosted Scalar Docs; medium for self-hosted API references, which need their own llms.txt route.
