Margin: open-source Mintlify-compatible docs framework ships free hosting built for AI agents
ycombinator · x · 2026-11-11
Y Combinator boosted Margin, an open-source docs framework hosted by Manicule, positioned as basic infrastructure for the agentic web. It's fully Mintlify-compatible: existing docs.json configs and MDX files deploy unchanged, under Apache 2.0, with free hosting and no limits.
Key features:
- Written for people, read by agents: every page ships as Markdown with llms.txt, llms-full.txt, AGENTS.md, skill.md, an MCP server, /api/mcp and page.pdf endpoints on by default
- Full docs-site toolkit built in: ⌘K search, versions and locales, 40+ components, OpenAPI-powered API playground, Ask AI with source citations, light/dark themes
- Manicule observability: hosted sites auto-report agent traffic (which crawlers and coding agents read each page and what they couldn't find), ChatGPT/Claude/Perplexity answers citing your docs, and assistant recommendation vs. competitor mention rates
Sample data: one site logged 2,900+ agent page views in 30 days, 184 of 620 AI answers citing its docs, and a 30% mention rate. The thesis: docs are shifting from human-facing pages to shared human-agent infrastructure, with quantified visibility into how AI consumes them.
