Console’s review

· Reviewed by David Mytton

What we like

Parses log lines to highlight various data formats e.g. dates, IPs, UUIDs, numbers, HTTP methods, etc. Highlighting rules are configurable. Can watch files in a directory and follow files. Uses less as the pager, so supports keyboard navigation, search, and filtering.

Tradeoffs

Takes a long time to load large logs - more designed for piping/streaming. Doesn’t work on Windows.
