Log Timeline Visualizer

Problem it solves

During an incident, hunting through thousands of interleaved log lines to work out what happened, in what order, is slow and error-prone.

Features

• Parses ISO 8601, syslog, US-date and Unix-epoch timestamps
• Detects log levels (TRACE to FATAL) with color-coded highlighting
• Groups related lines into flows by request/trace ID or worker-thread session
• Flags slow gaps between events
• Collapses stack traces for cleaner error visibility
• 100% client-side, so your logs never leave the browser

How it works

Paste plain-text or JSON logs (even mixed formats). The parser auto-detects timestamps, levels and correlation IDs, groups lines into request flows, and renders a chronological timeline with time deltas between events.
