# Fast Index Google > Free multi-bot crawlability toolkit: submit any URL and Fast Index Google fetches it as a normal browser, as 19 search-engine crawlers (Googlebot, Bingbot, YandexBot, Baiduspider, …) and as the three major AI agents (GPTBot, ClaudeBot, PerplexityBot) — reporting real HTTP status, redirects, robots.txt rules, sitemap presence and content differences for every user agent. No API keys, no quotas, no signup. Fast Index Google answers one question better than anything else: what do crawlers actually see when they fetch your page? Results are real fetches with real responses — no estimates, no scores. ## Tools - [Multi-bot crawl dashboard](https://fast-index-google.pages.dev/): Paste any URL (or a batch, one per line) and see exactly which crawlers can reach it — per-bot HTTP status, response time, blocked flags, content-match detection, a full robots.txt matcher and sitemap check, with CSV export and live polling. - [Rich text & page checker](https://fast-index-google.pages.dev/checker): Readability (Flesch score, grade level), keyword density, stop-word ratio, long-sentence detection and reading time for pasted text — plus a full on-page SEO audit and Google PageSpeed Insights scores for any live URL. All analysis runs locally; nothing is stored. ## Documentation - [How it works](https://fast-index-google.pages.dev/how-it-works): The five-step crawl pipeline — reference crawl, robots.txt matching, sitemap check, the 19-bot matrix and report/retry/export — plus the edge architecture (Cloudflare Pages Functions, D1 and a Durable Object scheduler). - [Docs & API](https://fast-index-google.pages.dev/about): API reference for every public endpoint (submit, jobs, stats, checker, settings), the admin settings shape, deployment notes and the full FAQ. - [Top 10 free SEO tools](https://fast-index-google.pages.dev/tools): The best genuinely-free tools for crawling, indexing, Core Web Vitals, backlinks and structured data, with honest free-tier limits and a combined weekly workflow. - [Contact & support](https://fast-index-google.pages.dev/contact): Bug reports, crawl-accuracy questions and feature requests, with a checklist that makes reports reproducible on the first attempt. ## Optional - [Privacy policy](https://fast-index-google.pages.dev/privacy): What is stored (submitted URLs and their crawl results), what is not (no accounts, no cookies, no advertising profiles), and how data is deleted. - [Terms of service](https://fast-index-google.pages.dev/terms): Usage terms for the free toolkit. - [llms.txt](https://fast-index-google.pages.dev/llms.txt): This file.
