Splunk is a powerful and feature-rich log management and analytics platform with robust capabilities suited for large enterprises, but it comes with high costs and complexity. In contrast, Graylog is an open-source alternative that offers good functionality for smaller environments, with a user-friendly interface and cost-effectiveness, but lacks some of the advanced features found in Splunk.
