About this tool
Log files are the ground truth of crawling. Upload an Apache/nginx access log (up to 50 MB) and the analyzer — running fully in your browser, nothing uploaded to a server — breaks down hits by bot, status code, most/least crawled URLs, crawl frequency over time and wasted crawl budget on 404s and redirects.
How to use the Log File Analyzer
- Export an access log from your server or CDN.
- Drop the file into the analyzer (processed locally).
- Review bot activity, status distribution and top crawled paths.
Frequently asked questions
Is my log data private?
Yes — parsing happens entirely in your browser; the file never leaves your machine.
Which log formats are supported?
Common/Combined Log Format from Apache, nginx and most CDNs.
