ClickStack

ClickStack is an OpenTelemetry-compatible, open-source observability platform that unifies logs, traces, metrics and sessions in a single high-performance data store built on ClickHouse. As infrastructure grows and observability costs increase, many teams struggle with fragmented telemetry toolchains and expensive vendor platforms. ClickStack addresses this challenge by leveraging ClickHouse’s columnar storage to enable sub-second, high-cardinality queries across large volumes of telemetry data, offering a simpler and more cost-effective foundation for observability.
