Datadog → OpenObserve / SigNoz
hardDatadog bills can hit $50k/mo for mid-size teams. OpenObserve and SigNoz are open-source, OTel-native and run on object storage for cheap retention.
OpenObserve: Rust-based, very cheap S3 storage. SigNoz: more polished UI, ClickHouse-backed. Both speak OTLP.
Helm chart on K8s or docker-compose on a VPS. SigNoz Cloud and OpenObserve Cloud also available if you want managed.
Replace Datadog SDK calls with OpenTelemetry SDK. Most languages: dd-trace → @opentelemetry/sdk-node + auto-instrumentations.
