Proprietary Vendor: Datadog•Monitoring & Status

Best Open Source Alternatives to Datadog & New Relic

Open-source infrastructure monitoring, metric visualization, and distributed tracing without unpredictable usage-based billing.

Why Migrate from Datadog & New Relic?

Datadog and New Relic pricing is notoriously punitive, penalizing growing infrastructure with runaway bills for custom metrics, log ingestion, and host counts. Modern open-source monitoring stacks deliver enterprise-grade dashboards, Prometheus scraping, and instant alerting while keeping operational telemetry inside your private VPC.

⚠Unpredictable monthly invoice spikes driven by runaway log ingestion and custom metrics
⚠Proprietary agent bloat consuming host memory and CPU cycles
