Multi-format JSONL, access, and syslog viewer with pattern clustering

Structured Log Viewer is a fast desktop log analyzer and stream explorer for JSON-Lines (.jsonl), Nginx and Apache web access logs, and syslog or timestamped application logs on Linux. Built for backend engineers and operations teams who want instant filtering, spike visualization, and clean exports without heavy cluster setups.

Key Features:

  • Multi-Format Log Explorer: Parses JSON-Lines (.jsonl and structured streams), Nginx and Apache access logs, and syslog or timestamped application logs with instant level filtering (ERROR, WARN, INFO, DEBUG), regex search highlighting, and a raw surrounding context inspector.
  • Time-Bucket Histogram & Top Error Patterns: Renders a timeline histogram highlighting event and error spikes per minute or hour alongside normalized template clustering that groups variable numbers and IDs to rank top errors.
  • Filtered Log Slice Exporter: Exports filtered and optionally masked log slices to plain .log, structured .jsonl, tabular CSV, and self-contained HTML summary reports.

Disclaimer: Structured Log Viewer is an independent open-source project by TC Studio and is not affiliated with, endorsed by, or sponsored by lnav.
