Agent Ready HTML

Webflow: vendor profile

In short

Webflow ties its agent features to plans. Markdown for agents needs an Enterprise workspace on its Cloudflare setup, and a free Starter site cannot upload llms.txt. Five markdown requests to webflow.com on 2026-11-05 returned markdown twice and HTML three times. Basic costs $15 a month on yearly billing.

What it does for this layer

  • Webflow's about page gives 2013 as its founding year and lists 300k organizations using Webflow and $335M in funding to date. [primary source] source, read 5 November 2026.
  • On 2026-11-05 the Webflow pricing page listed Starter as free with a webflow.io domain and 2 static pages, Basic at $15 a month billed yearly, and a new Premium plan at $25 a month billed yearly that adds Webflow CMS and well-known files. [primary source, 2026-11-05] source, read 5 November 2026.
  • Webflow's plan comparison marks both the Robots.txt & LLMs.txt row and the Schema markup support row with a note that a free Starter site needs a paid Workspace plan before either feature works. [primary source] source, read 5 November 2026.
  • Webflow switches on Markdown for agents per site under Site settings, Publishing, Advanced publishing options, and only for sites on a custom domain that have been migrated to Webflow's Cloudflare infrastructure under an Enterprise Workspace plan. [primary source] source, read 5 November 2026.
  • Five curl 8.7.1 requests to webflow.com with Accept: text/markdown on 2026-11-05 returned the 65,585-byte markdown version twice and the 553,434-byte HTML page three times, all as Cloudflare cache hits, and only the markdown answers carried Vary: accept. [observed, 2026-11-05] source, read 5 November 2026.
  • Since an update dated 2026-08-20, each URL in Webflow's auto-generated sitemap carries a <lastmod> timestamp, the sitemap can use the canonical URL as its domain, and publishing a single page refreshes it. [primary source, 2026-08-20] source, read 5 November 2026.
  • Webflow writes the sitemap.xml address into robots.txt on its own, and dropping that line with the Remove sitemap.xml from robots.txt toggle under Site settings, SEO, Indexing needs a paid Site plan. [primary source] source, read 5 November 2026.
  • Webflow keeps robots.txt rules in Site settings, SEO, Indexing, and adding any rule there takes a Site plan or a paid Workspace plan. [primary source] source, read 5 November 2026.
  • Webflow page settings carry a Schema markup field that Webflow AI can fill, markup saved there is published in the page <head>, and Reference, Multi-reference and Multi-image Collection fields cannot be bound into it. [primary source] source, read 5 November 2026.
  • The Webflow Data API v2 returns a site's robots.txt rules and sitemap URL from GET /v2/sites/{site_id}/robots_txt, an endpoint limited to Enterprise workspaces and the site_config:read scope. [primary source] source, read 5 November 2026.
  • Webflow's well-known file endpoint, PUT /v2/sites/{site_id}/well_known, is Enterprise-only and accepts fewer than 30 files, each under 100kb, with a .txt, .json or .noext extension. [primary source] source, read 5 November 2026.
  • Webflow says its hosting runs on AWS infrastructure behind Cloudflare's CDN with 99.99% uptime, and that Webflow Cloud adds server-side rendering for apps built with Next.js and Astro on the same domain. [vendor claim] source, read 5 November 2026.
  • Webflow places the editable 404 page under Utility Pages in the Pages panel and refuses Collection lists on it, so the page still renders when the CMS is down. [primary source] source, read 5 November 2026.
  • A curl 8.7.1 GET for /this-page-does-not-exist-ora-check on webflow.com on 2026-11-05 came back with HTTP 404 and a 5,571-byte text/html body. [observed, 2026-11-05] source, read 5 November 2026.

What it does not do

  • Webflow AI does not generate schema markup in a site's secondary locales during the localization beta, so markup there is written by hand.
