SmartDev Tools SEO Log File Analyzer
What it is
SmartDev Tools SEO Log File Analyzer is a free browser tool for examining server access logs. It shows bot traffic, leading crawlers, AI bot share, and possible wasted crawl budget. Reports include what Googlebot fetches and bot requests that produce 404s, redirects, or server errors. Users can paste or upload Apache or Nginx logs in combined format. The analyzer recognizes search crawlers, AI bots such as GPTBot and ClaudeBot, and SEO crawlers including AhrefsBot and SemrushBot. JavaScript reads and parses files in the browser; the page says log lines, IP addresses, and URLs are not uploaded. Lines in other formats are counted as skipped. Files up to about 20 MB are handled comfortably, with a recent slice suggested for larger logs. SmartDev Tools says there is no API and the tool is intended for manual, in-browser use.
