How It Works

A high-performance local web server log analytics tool. Ingests Apache Common (CLF), Combined, and Nginx access logs entirely within browser memory. Computes status code breakdowns (2xx, 3xx, 4xx, 5xx), discovers high-frequency 404 URLs, monitors bandwidth consumption, and audits bot hits with zero network leakage.

Privacy & Processing

100% client-side execution · No log content, IP addresses, or URL paths are ever uploaded to any server. Unlike ad-supported directories, there are no third-party trackers, promotional popups, or artificial download delays.
