ClickHouse-powered APM with 100% trace sampling and affordable retention

Uptrace is an OpenTelemetry-native APM platform that stores traces, metrics, and logs in ClickHouse for high-performance querying with 100% trace sampling. Unlike platforms that sample traces to control costs, Uptrace retains every trace for complete visibility into system behavior. Self-hosted under BSL license or available as a managed cloud service with affordable per-event pricing.

Open-source observability platform unifying logs, traces, and session replays

HyperDX is an open-source observability platform that correlates session replays, logs, metrics, traces, and errors in a single interface powered by ClickHouse and OpenTelemetry. Acquired by ClickHouse in 2025, it now forms the visualization layer of ClickStack. It offers schema-agnostic querying on any ClickHouse cluster, intuitive full-text and property search syntax, and blazing-fast analytics. Available as a self-hosted Docker deployment or a managed cloud service with a free tier.
