HTML Export

Try it now

Open the interactive demo → — Drop a PostgreSQL log file and explore the report. All processing happens locally in your browser; your data never leaves your machine.

Generate standalone HTML reports that can be viewed in any browser without a server.

# Generate HTML report (creates report named after input file)
quellog /var/log/postgresql/postgres.log --html
# → Creates postgres.html

# With filters
quellog /var/log/postgresql/*.log --dbname production --html
# → Creates quellog_report.html

Features

  • Self-contained: Single HTML file with embedded data and viewer
  • Interactive charts: Zoomable time-series visualizations
  • Client-side filtering: Filter by database, user, application, host, and time range
  • No dependencies: Works offline, no server required

How It Works

The HTML report embeds zstd-compressed JSON data, decoded client-side via fzstd. The same analysis data available with --json is rendered in an interactive interface.

Comprehensive Reports

Use --full to include all sections with detailed SQL analysis:

quellog /var/log/postgresql/*.log --html --full
