Built with Each entry says what gave it away: a response header, a cookie's name, an asset's path or file name, or markup the tool leaves in the page. 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.
- Prerenderedx-nextjs-prerender headerApp 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).
- Served from cacheVercel · made 72 s ago
- Cache-Control
- public, max-age=0, must-revalidate
- Server codeWhere the site's server code ran for this request, from the host's request ID. The edge location near heade.rs isn't shown: it's wherever the request came from.
- Washington, D.C. iad1Vercel Functions
- HTML
- Over 1 MB · sent Brotli-compressed
- 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.
- React Server Components 22.8 KB
- Scripts
- 10 files · 9 inline1 from other sites
- Render-blockingPlain scripts in the page's head, without async, defer or type=module. The browser shows nothing until each one has downloaded and run.
- 1 script
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.
- Tag manager
- Google Tag Manager
- Integrity checksSubresource Integrity: the script tag carries a hash of the file, so the browser refuses it if the other site changes it. Analytics and tag manager scripts change by design and can't carry one; pinned library files can.
- 0 of 1 script
AI & agents

robots.txt lets every AI crawler in. Agents that ask for Markdown get 1015 B instead of more than 1.0 MB of HTML.
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.

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.
- 2,386 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 request1015 B, over 1033× smaller
- llms.txtA Markdown file listing a site's key pages for AI tools. Coding agents read it; search crawlers mostly don't.
- 26 links in 6 sections
- Structured dataschema.org JSON-LD in the page: facts about the site in a form machines read directly.

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/.
No MCP server, API catalog, agent skills, shopping profile or in-page tools found.
