GoAccess is a fast, terminal-based log analyzer that provides real-time web server statistics without needing a browser. It supports nearly all log formats, including Apache, Nginx, Amazon S3, and CloudFront. Beyond analytics, it's a practical security tool for spotting suspicious activity, brute-force attempts, and bots. It can generate real-time HTML, JSON, and CSV reports, and is written in C with only ncurses as a dependency.
