What GoAccess is

GoAccess is a free, open-source, MIT-licensed web log analyzer and interactive viewer for system administrators. It produces terminal reports and can generate HTML, JSON, or CSV output. Users can provide custom log-format strings or choose formats for Apache, Nginx, Amazon S3, Elastic Load Balancing, and CloudFront. Terminal panels refresh every 200 milliseconds, while HTML output updates every second. The scrollable dashboard lets users reorder or expand panels. GoAccess can help identify suspicious traffic, brute-force attempts, scanners, bots, and anomalous requests. It can persist processed data on disk and append new logs without parsing the full dataset again. Real-time dashboards support local or external JWT verification and token refresh when built with OpenSSL. ASN mapping uses GeoIP2 data for the exclude-ASN option. Docker images are supported; ncurses is required, with GeoIP, OpenSSL, and zlib optional.

Verdict

GoAccess focuses on real-time web-log analysis rather than product analytics features. Its terminal dashboard, multiple output formats, security-oriented views, and incremental processing make it suitable for administrators managing their own logs.
