Netlify has owned the project since 2023. The docs read say nothing about llms.txt or MCP and describe no default JSON-LD; the most recent npm release is nine months old. ## At a glance Type [Framework](https://agentreadychecklist.com/vendors/by-type/framework/) Operator Netlify Homepage [gatsbyjs.com](https://www.gatsbyjs.com), answered HTTP 200 on 2026-11-05 Checklist rows 9 of 31 read: **1** supported, 2 partial, 6 no statement In the crawl 28 of 5,897 home pages counted on 2026-11-04.
