Parse Logs with the Power of AWK

High-density log analysis for DevOps specialists. Transform messy streams into structured insights with millisecond latency, directly in your browser.

Parsing happens locally / securely

Extreme Speed

Web Worker parsing keeps the UI responsive on large access logs. Zero server round-trips for processing.

Preset Library

One-click presets for Apache, Nginx, WordPress admin-ajax, status codes, top IPs, URLs, and user agents.

Live Preview

See parsed rows and summary stats update as soon as your file finishes processing in the browser.

Security first

Your data never leaves your browser.

Traditional log analyzers require uploading sensitive production logs to their servers. AWK_LOG_PARSER runs entirely client-side, ensuring compliance with strict privacy policies while providing high-performance tools.

  • Local File API only
  • Zero-retention policy
  • Open source friendly
