How It Works: Client-Side Processing
Your privacy is our priority. Here's why our approach is different:
Pattern Recognition
Intelligent parsers recognize Apache and Nginx log formats automatically without configuration.
Filtering
Filter logs by status code, IP address, path, or time range to focus on relevant entries.
Local Processing
All log parsing and analysis happens in your browser. Your server logs never leave your device.
Frequently Asked Questions
Are my log files uploaded to any server?
No. All log parsing and analysis happens entirely in your browser using JavaScript. Your server logs, IP addresses, and request data never leave your device.
What log formats are supported?
We support Apache and Nginx access logs in Combined Log Format and Common Log Format. These are the default formats used by most web servers.
How large a log file can I analyze?
The tool can handle log files of several hundred megabytes, limited only by your browser's memory. For very large files, consider splitting them into smaller chunks.
