What engineers like:
Point at a directory and it auto-detects file formats, parses, colorizes, merges, and displays them in your terminal. Can pretty print structured data e.g. JSON. Search as you type also streams in new log lines. Sessions can be restored. Query and filter the logs with SQL, which includes “virtual tables” to allow for comments, tags, and bookmarking.
Trade-offs & limitations:
Official downloads don’t include Arm binaries (although the macOS version via Homebrew is compiled for Apple Silicon). Does not inherit the terminal theme - need to configure custom colors separately.
Best suited for:
Developers who work with log files should consider this tool
