# The open-source docs framework.

Bring your Mintlify docs as they are. Host them free on Manicule, or run them yourself.

[Deploy free on Manicule](https://app.manicule.com/onboard?product=margin) · [View on GitHub](https://github.com/maniculehq/margin)

- **docs.json, read as is:** Mintlify config and MDX
- **Read by agents:** llms.txt and an MCP server
- **Search and Ask AI:** Answers that cite sources
- **Free for good:** Apache 2.0, no limits

## Bring your docs.json.

Your Mintlify config and MDX deploy unchanged. Unknown fields only warn.

## Everything a docs site needs.

Built in, on every site. No plugins, no paid tiers.

- **Search with ⌘K** Every page, heading and endpoint, instantly.
- **Versions and languages** Every release, in every locale.
- **Over 40 components** Steps, tabs, cards, callouts and more.
- **API playground from OpenAPI** Every endpoint gets a page you can try.
- **Answers with sources** Ask AI cites the pages it used.
- **Light and dark** Both themes, from your own tokens.

## Written for people. Read by agents.

Every page ships as Markdown, with llms.txt and an MCP server. On by default.

And on every site: `/llms.txt`, `/llms-full.txt`, `/AGENTS.md`, `/skill.md`, `/api/mcp`, `/page.pdf`

## Know when AI picks you.

Hosted sites report to Manicule on their own. Nothing to install.

- **Agent traffic:** Which crawlers and coding agents read each page, and what they couldn’t find.
- **AI citations:** The ChatGPT, Claude and Perplexity answers that cite your docs.
- **Visibility:** How often assistants recommend you, and who they name instead.
