What ClickStack is
ClickStack is an open-source observability stack that brings OpenTelemetry logs, metrics, traces, session replays, and errors into one system. Its HyperDX interface provides Lucene-style search and SQL access, along with dashboards, alerts, event deltas, and event patterns. ClickStack uses ClickHouse storage and is designed to query high-cardinality OpenTelemetry data; its site describes sub-second queries even at petabyte scale. It supports OpenTelemetry natively and includes a bundled OpenTelemetry Collector. Teams can also send wide event data outside the OpenTelemetry format if it includes a timestamp field.
ClickStack can be deployed self-hosted, in a hybrid setup, or in the cloud. Its open-source components use Apache 2.0 licensing for ClickHouse and the OpenTelemetry Collector, and MIT licensing for HyperDX. The managed service runs on ClickHouse Cloud and includes cluster operations, scaling, upgrades, backups, reliability, authentication, and user management. Managed ClickStack advertises indefinite retention for high-cardinality telemetry and storage pricing below one cent per GB. The listed plans are ClickStack Open Source at no cost and a managed trial at no cost, with ClickHouse Cloud credits and a 30-day maximum trial period. Its listed platforms are API, self-hosted, and web.
