IconVault's Log Parser turns messy log output into something you can actually read. Paste or upload a log file and it auto-detects the format (Apache/Nginx combined, JSON lines or plain text), tags every line with its level (info, warn, error, debug), and shows per-level counts so you know exactly where the problems are.

Filter lines by severity, search across the full log, and copy or inspect only what matters. Everything runs fully in your browser with nothing uploaded, so even sensitive production logs stay private. It is free to try (repeated use may ask for Pro).
