ClickStack
ClickStack is an open-source observability stack for OpenTelemetry that brings logs, metrics, traces, session replays, and errors together.
What ClickStack is
ClickStack is an open-source observability stack for OpenTelemetry that brings logs, metrics, traces, session replays, and errors together. Collection is supported natively through OpenTelemetry and a bundled collector; custom wide-event data can also be used when it has a timestamp field. In the HyperDX interface, users can search with Lucene-style queries, access SQL, build dashboards and alerts, and inspect event deltas and patterns. ClickHouse storage is designed for high-cardinality telemetry, with the product describing sub-second queries even on petabytes of data. ClickStack can be deployed self-hosted, in hybrid setups, or in the cloud. Its open-source plan is free, and a managed-service trial is also listed as free for up to 30 days or until its $300 in ClickHouse Cloud credits are used. The managed service handles operations such as scaling, upgrades, backups, authentication, and user management. Listed capabilities also include structured log parsing, live log tailing, and archive export; log pipelines are not included.
