Datadog removes data-plane operations, but sends telemetry into a managed SaaS and prices observability across host, volume, retention, and product meters. MoleSignal keeps four signal families and their investigation context on infrastructure you control.
Compare · Datadog
The decisive difference is who owns storage and how cost grows. MoleSignal turns observability into infrastructure you control; Datadog attaches separate meters to hosts, intake, indexing, retention, and products.
| Decision point | MoleSignal | Datadog |
|---|---|---|
| Deployment | Self-hosted standalone or multi-role deployment; Kubernetes manifests are available. | Managed Datadog service with agents or OpenTelemetry components forwarding telemetry to a Datadog site. |
| Commercial model | Apache 2.0 core with no software license fee; you pay for your infrastructure and optional support. | Separate product meters include per-host and usage-based pricing; exact rates depend on product, retention, and commitment. |
| Signals | Logs, metrics, traces, and continuous profiles, plus dashboards and three alert rule kinds. | A broad platform spanning infrastructure, APM, logs, profiling, digital experience, security, service management, and more. |
| Investigation context | Logs, metrics, and traces share tenant, time, object-storage, and query context; profiles join the same investigation plane. | Datadog documents correlation across traces, metrics, logs, processes, network data, and other products. |
| Collection | OpenTelemetry-native OTLP plus Prometheus remote_write, Loki, Elasticsearch bulk, and other compatible inputs. | Datadog Agent and a large integration catalog, with documented OpenTelemetry support. |
| Data boundary | Telemetry stays inside infrastructure, Postgres, and object storage you control. | Telemetry is stored and processed in Datadog’s managed service rather than your infrastructure. |
Migration
Do not start with a full cutover. Keep instrumentation portable and compare one representative service end to end.
Route a copy of OTLP telemetry to MoleSignal while Datadog remains the production system of record.
Recreate one high-value dashboard and the alert that normally starts an incident.
Test the exact metric → trace → log → profile investigation with a real failure window.
Measure retained data, query latency, operator time, and infrastructure cost before expanding the scope.
Official sources
Product capabilities, editions, and prices change. Re-check the linked first-party sources before making a procurement or production decision.
MoleSignal is pre-1.0; validate it with your workload before production use. MoleSignal is not affiliated with Datadog, Grafana Labs, Elastic, SigNoz, or OpenObserve. Product names are the property of their respective owners.
Replace five signal components and several query languages with one data plane and one incident path.
Run an Apache 2.0 observability data plane without adopting Elasticsearch, Kibana, and their broader operational footprint.
Keep OpenTelemetry data on object storage and add first-class profiles without making ClickHouse a core dependency.
Keep Apache 2.0 and first-class profiles without an AGPL/commercial-license split or NATS in the HA path.
Start the self-hosted sandbox, send a representative OTLP workload, and test the investigation path your team uses during a real incident.
