Pricing: https://agentreadychecklist.com/pricing.md (free). # Astro Astro prerenders pages to HTML by default, which meets AR-READ-01, and adds no robots.txt or bot blocking of its own, which meets AR-FIND-01. The sitemap, llms.txt, markdown twins, JSON-LD and a Content-Signal line each need an integration or code. The docs read describe no MCP server for sites built with Astro. ## At a glance Type [Framework](https://agentreadychecklist.com/vendors/by-type/framework/) Operator Cloudflare Homepage [astro.build](https://astro.build), answered HTTP 200 on 2026-11-05 Checklist rows 11 of 31 read: **2** supported, 8 partial, 1 no statement In the crawl 25 of 5,897 home pages counted on 2026-11-04.

Counted from the shared crawl of 2026-11-04 by generator meta tag in the home page HTML; the generator rule only sees tags whose name attribute comes first, so it undercounts | 2026-11-04 | agentreadychecklist.com/data/ | ## What it does not do - Astro does not generate llms.txt, markdown twins or a robots.txt without code or an integration. - Astro does not negotiate markdown on a static build; that needs on-demand rendering or a host rule. ## Reading notes Owner recorded as Cloudflare from the January 2026 announcement; the framework stays MIT-licensed. ## Related pages on this site Recipes [Astro](https://agentreadychecklist.com/platforms/astro/) ([checklist view](https://agentreadychecklist.com/platform/astro/checklist/)) Same recipe page [Starlight](https://agentreadychecklist.com/vendors/starlight/) Same type [Frameworks](https://agentreadychecklist.com/vendors/by-type/framework/), [all vendors](https://agentreadychecklist.com/vendors/) ## Sources - [astro.build](https://astro.build)read 2026-11-05 - [registry.npmjs.org/astro](https://registry.npmjs.org/astro)read 2026-11-05 - [astro.build/blog/joining-cloudflare/](https://astro.build/blog/joining-cloudflare/)read 2026-11-05 - [blog.cloudflare.com/astro-joins-cloudflare/](https://blog.cloudflare.com/astro-joins-cloudflare/)read 2026-11-05 - [astro.build/blog/astro-7/](https://astro.build/blog/astro-7/)read 2026-11-05 - [docs.astro.build/en/guides/on-demand-rendering/](https://docs.astro.build/en/guides/on-demand-rendering/)read 2026-11-05 - [docs.astro.build/en/guides/integrations-guide/sitemap/](https://docs.astro.build/en/guides/integrations-guide/sitemap/)read 2026-11-05 - [astro.build/blog/](https://astro.build/blog/)read 2026-11-05 - [docs.astro.build/en/basics/project-structure/](https://docs.astro.build/en/basics/project-structure/)read 2026-11-05 - [docs.astro.build/en/guides/endpoints/](https://docs.astro.build/en/guides/endpoints/)read 2026-11-05 - [docs.astro.build/en/basics/astro-pages/](https://docs.astro.build/en/basics/astro-pages/)read 2026-11-05 - [docs.astro.build/en/reference/directives-reference/](https://docs.astro.build/en/reference/directives-reference/)read 2026-11-05 - [isitagentready.com](https://isitagentready.com/)read 2026-11-05 - [agentreadychecklist.com/data/](https://agentreadychecklist.com/data/)read 2026-11-04 Edition Data 2026-11-04 Reviewed 2026-11-05 Spec AgentReady v2.0, 273d2d7 Crawl 13,071 rows, 2026-11-04 Ora 132 checks, contract 1.38.0, 2026-11-05 Verify with Ora The scanner this site recommends for the whole checklist. 132 checks, a score out of 100, no account. `npx ax@0.10 audit --min-score ` [Why Ora, and its limits](https://agentreadychecklist.com/verify-with-ora/) Method - [How rows, commands and rates are made](https://agentreadychecklist.com/method/) - [How an Ora check is matched to a row](https://agentreadychecklist.com/checklist/ora-checks/) - [Pass rates by rank band](https://agentreadychecklist.com/data/by-rank/) Sources and read dates sit at the foot of the page.
