Log Analysis GitHub Repositories (2026) · Open Source Tools

tirreno is an open-source framework for in-house security. Event tracking, risk scoring and threat detection for your system.

Log file navigator

Free editor for huge text and log files: opens 50 GB at once, searches at 2.5 GB/s, never freezes. A free alternative to EmEditor and UltraEdit for Windows, Linux and macOS. Written in Rust.

TUI for viewing logs from journald, auditd, file system, Docker and Podman containers, Compose stacks and Kubernetes pods with support for log highlighting and several filtering modes.

Local-first threat hunting for the logs you already have: Zeek, Pi-hole, syslog or the systemd journal, CloudTrail. Every run names the technique behind each detector. No agent, no daemon, no black box - between grep and a SIEM.

Find out why your Linux PC froze, crashed or shut down: whyd reads the journal of the previous boot and tells you in one screen.

Local-first, explainable log incident diagnosis for developers and CI/CD.
