hyperdx

HyperDX is an open-source observability platform for developers and DevOps teams that unifies session replays, logs, metrics, traces, and errors in a single interface powered by ClickHouse and OpenTelemetry. It enables rapid debugging of production issues by correlating user behavior with backend telemetry, eliminating the need to switch between multiple tools. Its interesting because it combines the full observability stack with session replay, offering a cost-effective, self-hostable alternative to proprietary solutions like Datadog or Sentry.
