Versions are checked against endoflife.date's support schedules and, for JavaScript packages, OSV's vulnerability database, which carries GitHub's security advisories.

How it's made
- RenderingPrerendered pages are built ahead of time and served as files. Pages rendered on each request are built by server code for every visitor. Pages drawn in the browser arrive nearly empty and depend on JavaScript, which most AI crawlers don't run. Islands are interactive parts in otherwise static HTML.
- PrerenderedNext.js getStaticPropsPages Router
- Edge cacheWhether a CDN or proxy answered heade.rs's request from its cache, and how long ago that copy was made (the Age header).
- Not cachedCloudflare
- Cache-Control
- max-age=0,no-cache
- HTML
- 168.6 KB
- Data for scriptsData the server writes into the HTML so JavaScript can pick up where the server left off (hydration). Browsers download and parse all of it before the page responds, so large payloads slow pages down, even when the page looks ready.
- Next.js page data 30.7 KB · 18% of the HTML
- Scripts
- 20 files · 4 inlineall from this site
Code from other sites Scripts a page loads from another domain run with the same power as its own code: they can read what visitors type and change the page. heade.rs checks what the HTML loads, not what tag managers add once they run.

AI & agents
Mixed signals about AI use
robots.txt says ai-train=no, but its Markdown responses send ai-train=yes, which Cloudflare's Markdown for Agents sends when the site doesn't set its own.
Crawlers
Allows allTrainingSearchOn request
They visit a page when someone asks an assistant about it. ChatGPT's, Perplexity's, Meta's and Amazon's treat robots.txt as advisory;
Anthropic's and Mistral's follow it.

- Can cite itThe AI products that can use the site in their answers: each answers from one crawler (OAI-SearchBot for ChatGPT search, Googlebot for AI Overviews, bingbot for Copilot), and robots directives on the front page, like noindex, nosnippet and noarchive, keep some out.

robots.txt says ai-train=no, but its Markdown responses send ai-train=yes, which Cloudflare's Markdown for Agents sends when the site doesn't set its own.
Content signals Lines in robots.txt (Cloudflare's Content Signals Policy) saying whether pages may be used for search, as input to AI answers (ai-input) and for AI training. No major AI company has said it follows them. search=yesai-input=yesai-train=noIt's on Cloudflare, which can also block AI crawlers at its edge whatever robots.txt says.
Reading
- Without JavaScriptText on the front page before any scripts run: what GPTBot, ClaudeBot, PerplexityBot and most agents read. Google, Bing and Apple's crawlers run scripts.
- 1,426 words
- MarkdownAgents like Claude Code, Cursor and OpenCode ask for Markdown in their Accept header. It's the page without its markup, so it costs them far fewer tokens.
- On request16.3 KB, 10× smaller · converted by Cloudflare
- llms.txtA Markdown file listing a site's key pages for AI tools. Coding agents read it; search crawlers mostly don't.
- 21 links in 12 sectionsno title line
- Structured dataschema.org JSON-LD in the page: facts about the site in a form machines read directly.
- Corporation
Tools Ways an AI agent can do things on the site, not just read it: an MCP server that apps like Claude, ChatGPT and Cursor connect to, an API catalog, packaged agent skills, a shopping profile (UCP), or tools the page offers AI in the browser (WebMCP). heade.rs looks in the official MCP Registry and the files the site publishes under /.well-known/.
- APIsAn API catalog (RFC 9727, at /.well-known/api-catalog) lists a site's APIs and links to their machine-readable descriptions, usually OpenAPI.
- 1 in its API catalogwww.workable.com · OpenAPI
- Agent skillsInstructions and scripts packaged for AI agents (SKILL.md), listed in an index at /.well-known/agent-skills/index.json or in the site's AI Catalog. Tools like Vercel's skills CLI install them.
