Can AI assistants read prisma.build?

Measured on 2026-09-19 by asking the site 7 times — once as a browser, once as each of the 6 crawlers that feed ChatGPT, Claude, Perplexity, Gemini, Meta AI, Apple Intelligence and Doubao — and comparing what came back. The AI-training opt-out tokens that never crawl are read from robots.txt instead.

D60 / 100
3 of 6 crawlers can read this page.
More readable than 19% of the 47,315 sites measured so far. No JSON-LD.

What to change, in order

  1. Let in the 3 crawlers your own robots.txt already allows+3 crawlers
    ClaudeBot, GPTBot, OAI-SearchBot are turned away before reading the page (answered, but with far less text than a browser gets), while robots.txt permits them — so this block is not written in your site. No CDN signature was found in the response headers, so the refusal comes from the origin server itself or from a WAF this index does not recognise. Fixing it takes this domain from 3 to 6 of 6 crawlers.
  2. Declare the facts in JSON-LD
    There is no JSON-LD on the page, so every fact — who you are, what you sell, the price — has to be guessed out of the prose and the layout. A schema.org block is the difference between being quoted correctly and being paraphrased.
  3. Publish sitemap.xml and llms.txt
    sitemap.xml and llms.txt are missing, so an assistant has to discover the site by following links. llms.txt is the emerging convention for telling an assistant which pages actually matter.

Method. 7 live HTTP requests (one per crawler, one as a browser) plus robots.txt, llms.txt, sitemap.xml and security.txt, 12-second timeout each, from a single vantage point. Blocking AI crawlers is a legitimate choice, not a failure: this page records what is true, not what should be. Domain comes from a shop-platform seed (Shopify/WooCommerce/Magento/BigCommerce/Shopline fingerprint or JSON-LD price), not the Tranco traffic ranking. One page per domain — the homepage — is audited.
