Open-Source & Self-Hosted Alternatives to Datadog & New Relic
Enterprise full-stack observability notorious for unexpected five-figure monthly invoice shocks.
Why Migrate Away from Datadog & New Relic?
Datadog charges per host, per metric, per log GB, and per trace. For microservices or Kubernetes clusters, bills quickly spiral out of control. Modern OpenTelemetry-native self-hosted stacks provide logs, metrics, and APM distributed tracing on your own NVMe storage for zero variable data costs.
