Margin

Teams that already write documentation for Mintlify can move it to Margin without rewriting it. Margin reads the Mintlify configuration file and MDX pages as they are, and warns rather than fails on fields it does not recognise.

## What a docs site includes

The site lists more than 40 components such as steps, tabs, cards and callouts, an API playground generated from an OpenAPI spec with a testable page per endpoint, search with Ask AI that cites the pages it used, multiple versions and languages, preview deploys on each pull request, and custom domains. Every page is also published as Markdown with llms.txt, AGENTS.md, skill.md and an MCP server, so coding agents can read the docs. The launch post adds that agents can write documentation autonomously.

## Hosting and agent reporting

Margin is free to host on Manicule with no limits, or can be run on Vercel or any Node server under the Apache 2.0 licence. Hosted sites report which crawlers and coding agents read each page, which AI answers cite the docs and how often the product appears. Manicule, Inc. also sells documentation, content and agent-visibility services, and the compatibility claims are the makers' own.

Not yet independently verified: Dated from the Y Combinator launch post of 10 November 2026, as the site gives no launch date. The compatibility claims are the makers' own, and the pages name no city or country. We will update this when it can be confirmed, and remove this note.
