ClickStack review
A broad open-source stack for correlating logs and telemetry with SQL, search, and dashboards.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
ClickStack is an open-source observability stack from ClickHouse for engineering and operations teams that need to ingest and analyze logs, metrics, traces, session replays, and errors in one environment. It combines ClickHouse storage, the HyperDX interface, and OpenTelemetry collection, making it a fit for teams that want log management alongside wider telemetry correlation. Web, API, and self-hosted options support different deployment models, while native JSON and semi-structured data handling suits applications producing varied event formats.
Its strongest distinction is breadth without abandoning familiar investigation tools. Lucene-style log search supports text-oriented exploration, while full SQL querying gives technical teams a more structured way to analyze data. Dashboards and alerting extend the product beyond search, and automatic correlation connects logs, traces, and metrics. Session replay support adds application-context investigation, while CSV export supports moving search results into other workflows. Integrations include OpenTelemetry, AWS, Cloudflare, Fluentd, Kubernetes, and common development languages and frameworks such as Node.js, Go, Java, JavaScript, Next.js, Python, and Ruby.
ClickStack offers an open-source self-hosted edition and a managed option on ClickHouse Cloud. The published plans include a free plan and a 30-day free trial, while managed usage is described as infrastructure-based and usage-dependent rather than a fixed paid-plan price. Self-hosting can suit teams that want deployment control, but it also places infrastructure responsibility with the organization. Choose ClickStack when open-source flexibility, SQL, pipelines, dashboards, alerting, and cross-signal correlation matter together. A narrower log-search tool may be a better fit for teams that do not need metrics, traces, replay, or broader observability workflows.
