What is LogLens?

LogLens is a high-performance terminal tool designed to replace jq, grep, and tail -f for structured log analysis.

Unlike traditional tools, LogLens automatically detects JSON, Nginx and Logfmt structures, allowing you to filter logs using SQL-like logic (e.g. level == 'error' && latency > 500) or natural syntax (e.g. level is error and latency > 500) instead of complex regex. It features a live TUI (Terminal User Interface) for interactive filtering and real-time monitoring.

Key Features:

  • Zero-Config Parsing: Automatically parses JSON/Nginx/Logfmt.
  • Structured Query Engine: Filter by field values, not just text.
  • Live Watch Mode: Tail logs with real-time highlighters.
  • Local & Private: Runs entirely on your machine; no data leaves your server.
  • Open Source Core: Powered by the MIT-licensed loglens-core engine.
