ClickStack vs Splunk Enterprise

ClickStack is an open-source observability stack for OpenTelemetry that brings logs, metrics, traces, session replays, and errors into one system. Its HyperDX interface provides Lucene-style search, SQL access, dashboards, alerts, event deltas, and event patterns. A bundled OpenTelemetry Collector handles native collection, while non-OTel wide event data can be used when it has a timestamp field. ClickStack stores data in ClickHouse and is designed for high-cardinality telemetry, with the product site describing sub-second queries even on petabytes of data. It supports self-hosted, hybrid, and cloud deployment. Managed ClickStack runs on ClickHouse Cloud with operations, scaling, upgrades, backups, reliability, authentication, and user management included. The managed offer advertises indefinite retention and storage below one cent per GB. An MCP server connects observability workflows with coding tools, collaboration services, runbooks, and custom agents.
