Log Lens is a desktop log viewer built for searching and filtering huge log files (tested up to multi-gigabyte, tens-of-millions-of-lines files) without loading the whole file into memory. Features nested boolean search groups (build expressions like (A OR B) AND C through the UI), multi-file merge into a single timestamp-sorted timeline, log-level and method-name coloring, automatic detection and pretty-printing of embedded JSON payloads, and cursor-drag text selection for copying results.
