Pick OpenTelemetry if…
- You want observability data that isn't locked to a single vendor
- Instrumenting microservices with distributed traces across multiple languages
- Feeding telemetry into Datadog, Jaeger, Grafana, or any OTel-compatible backend
Pick SigNoz if…
- Teams wanting Datadog-quality observability without vendor lock-in or cost
- Self-hosted OpenTelemetry backend for traces, metrics, and logs
- Privacy-sensitive apps where sending telemetry to third-party SaaS is not acceptable

OpenTelemetry
import { NodeSDK } from '@opentelemetry/sdk-node';
import { getNodeAutoInstrumentations } from '@opentelemetry/auto-instrumentations-node';
const sdk = new NodeSDK({
traceExporter: new OTLPTraceExporter({ url: 'http://localhost:4318/v1/traces' }),
instrumentations: [getNodeAutoInstrumentations()],
});
sdk.start();SigNoz
# Self-host with Docker
git clone https://github.com/SigNoz/signoz.git
cd signoz/deploy && docker compose up -d
# Send traces via OpenTelemetry (OTLP endpoint)
# OTEL_EXPORTER_OTLP_ENDPOINT=http://localhost:4318
# Then use any OTel SDK — see opentelemetry entryCommunity Verdict
