Visiblio / Log Analyser
See what crawlers really do on your website.
Upload a server access log and see which pages Googlebot, Bingbot and AI crawlers (GPTBot, ClaudeBot, PerplexityBot...) visit, how often, and whether they get errors or redirects. The file is read in your browser: nothing is uploaded.
Shows the full result for an invented website, so you know what to expect before you upload a file. Nothing is uploaded.

How this works and what it can and cannot do
- The log is read line by line in your browser. Lines in Apache or Nginx "combined" format, and JSON lines, are understood; other lines are skipped and counted.
- Crawlers are told apart by the name in the user agent text. Anyone can fake that name, so for important decisions verify an address with a reverse DNS lookup (Google and Bing publish how).
- Visitors (normal browsers) are counted but not listed page by page. Addresses are grouped without their query string; the share of visits that had one is shown as parameter waste.
- A log only shows requests that reached your server. If a CDN answers without asking your server, those visits are missing: use the CDN's own log when you can.
