LogSonic is a Desktop-First Log Analytics application which runs on Windows, Mac and Linux. It runs fully offline with no external dependencies. It installs as a single self-contained binary that serves a feature-rich User interface in your local browser. The log ingestion wizard supports importing local log files (single or many at once) and automatically recognises well-known log patterns to tokenise the contents. The log search experience is blazing fast, delightful and intuitive.
