LogLens Playground

A command-line tool for structured log analysis that searches, queries, filters and summarizes large JSON and text log files, including compressed archives, to support troubleshooting and incident response. It is for software developers and operations engineers in business teams who work in the terminal. It runs as a local, dependency-free binary built in Rust that processes data on the machine without uploading logs.
