AI visibility (4)
llms.txt generator
Describe your site once; get a valid llms.txt to put at your root so AI assistants know what you are and where to look.
AI crawler check
Enter a domain; see which of 200+ AI crawlers (GPTBot, ClaudeBot, PerplexityBot, Google-Extended…) your robots.txt allows or blocks, and if you have an llms.txt.
AI bot blocker generator
Pick the AI bots to block; get the robots.txt block, a Cloudflare WAF expression, nginx, Caddy and .htaccess rules ready to paste.
How AI sees your page
Enter a URL; see the page as an AI assistant reads it: clean Markdown, heading tree, word count, links and images without alt text.
SEO (6)
Meta tag & social preview
Enter a URL; check title, description, canonical, robots, hreflang and Open Graph, and preview the Google, X, LinkedIn and WhatsApp cards.
Structured data check
Enter a URL; every JSON-LD block is parsed, flattened and checked for the required and recommended fields of its @type.
Redirect chain check
Enter a URL; follow every hop, catch loops, 302s that should be 301s, missing http→https and www inconsistencies.
robots.txt & sitemap check
Enter a domain; robots.txt syntax is checked and every sitemap is fetched: URL counts, lastmod coverage, size limits and broken XML.
IndexNow key check
Enter a domain and key; we fetch the key file the way Bing does and tell you exactly what is wrong if it fails. Or generate a new key.
SERP snippet preview
Type a title, description and URL; see the Google desktop and mobile snippet with pixel widths and truncation warnings.
Security (2)
Security headers check
Enter a domain; HTTPS redirect, HSTS, CSP, clickjacking, nosniff, referrer policy, exposed .env/.git files, security.txt, SPF and DMARC, each with a fix.
DNS & email security check
Enter a domain; A/AAAA/CNAME/NS/MX/TXT/CAA records plus SPF, DMARC, MTA-STS, DKIM and DNSSEC evaluated with fixes.
Infrastructure (3)
HTTP response check
Enter a URL; status, response time, server, Cloudflare and cache status, compression, HSTS and HTTP/3 in one table with plain-language notes.
Page weight analyzer
Enter a URL; count scripts, styles, images and preloads, find render-blocking resources and measure the first 30 by size.
Domain info (RDAP)
Enter a domain; registrar, creation and expiry dates, days left, status codes explained, name servers and DNSSEC from the registry's RDAP.
Bot list: ai.robots.txt (MIT). Server-side fetches run in a Cloudflare Worker, are cached for 60 seconds and never stored.
