Grafana vs Splunk

Splunk is the enterprise observability and security giant — powerful log analytics, SIEM capabilities, and machine learning on machine data. It's also legendarily expensive, with costs that can reach millions per year for large deployments. 'Splunk tax' is a real term in the industry.

Grafana (with Loki for logs, Mimir for metrics, Tempo for traces) provides comparable observability at a fraction of the cost. Self-hosted, it's free. Grafana Cloud is typically 80-90% cheaper than Splunk for equivalent data volumes.

Splunk's advantages: mature SIEM with pre-built security detections, SPL (Search Processing Language) is incredibly powerful for complex queries, and enterprise support/compliance certifications. For security operations centers (SOCs), Splunk remains the standard.
