What each one is
The product in its own terms, so the numbers below have context.
OpenObserve
LeaderOpenObserve is a cloud-native observability platform that unifies logs, metrics, traces, real user monitoring, and AI/LLM observability in a single system. Using Parquet columnar storage on object storage backends, it achieves significantly lower infrastructure costs than traditional platforms while supporting flexible deployment across cloud, on-premises, and air-gapped environments.
Splunk
Splunk consolidates data from various sources and enables real-time analysis for security monitoring, system observability, and AI applications. It supports analyzing data in place across different storage backends, reducing costs and data movement while providing complete operational visibility.
