Free sitemap validator that fetches every URL as 5 crawlers: Chrome, Googlebot, GPTBot, ClaudeBot & PerplexityBot. Checks XML syntax, live URL health, robots.txt per crawler, hreflang, fuzzy duplicates — and gives you an AI Discoverability score no other tool has. Detects 17 CMS platforms (Yoast, Shopify, Next.js…) and gives platform-specific fixes. No signup, no paid tier. 50 rules, 3 scores, 30 seconds.
