SigNoz
SigNoz is an open-source observability platform unifying traces, metrics, and logs, positioned as a self-hosted Datadog alternative. Its standout trait is using ClickHouse as a single high-performance backend for all telemetry types.

⚙ Full Stack
A Go query-service and TypeScript frontend, an OpenTelemetry Collector for ingestion, and ClickHouse as the columnar store for traces/metrics/logs, with Zookeeper for ClickHouse cluster coordination.
📈 Scaling Analysis
ClickHouse's distributed engine and the stateless OTel Collector both scale horizontally for high telemetry ingest volume, making SigNoz genuinely capable of internet-scale observability — the tradeoff is that ClickHouse cluster operations (sharding, replication, Zookeeper) add real operational complexity compared to a simple Postgres-backed app.
🚀 Running on Nexlayer
Deploy OTel-collector, query-service, frontend, and ClickHouse as separate pods linked via <podName>.pod:<port>; ClickHouse needs a sizable PVC and benefits from being pinned to a dedicated node for I/O. Mirror.gcr.io covers the OTel-collector and query-service base images.
