Klunk - Log Viewer (beta)

Local files, databases, Kubernetes pods, SFTP, HTTP get/post URLs. Opens logs directly inside .zip, .gz, .tar and .tar.gz archives, locally or over SFTP.

Combine files into one chronological stream with color-coded sources — or keep them separate and use Synch All to scroll every open log to the same time.

SQL-like syntax — LIKE, =, AND, OR, nested groups.

Pin important rows with multicolor bookmarks, comments, and time markers — then filter down to just what you've flagged, plus Bookmark time to mark the same moment across every open log.

Regex-based pattern engine supports Log4j, Logback, CSV, JSON, XML, key-value and custom formats. Formats are auto-detected, and a generator builds new patterns from a sample line.

Smaller logs stay fully in memory for speed; larger ones switch to SQLite-backed paging and handle millions of rows. The switch-over threshold is configurable in Settings.

Real-time monitoring with automatic file-rotation detection.

Saves and restores opened files, filters, window positions, and bookmarks.

Dual-thumb vertical slider with error/warning markers and live viewport tracking.

Dockable tabs, in-text search with highlighting, multicolor bookmarks, timestamp timezone conversion, light/dark theme, customizable table font/colors.

Error/warning reports and charts with best-effort redaction of sensitive data (includes custom find/replace overrides) before anything is copied or exported. (useful for AI prompting)

Side-by-side diff of pasted text or log rows with changed characters highlighted. Also compares lists ignoring order, and the gaps between timestamps.
