Grafana and Splunk are often evaluated together by teams building out their reliability stack. Grafana (open-source observability and data visualization, founded 2014) is typically a fit for Engineers, SREs, and Data Teams, while Splunk (enterprise observability platform for logs, metrics, traces, and security data at scale, founded 2003) leans toward Enterprise SRE, Security Operations, and Platform Engineering. Both cover 14 of the same core capabilities, so the decision usually comes down to where they diverge.
