10 Best Datadog Alternatives (2026)

Q: What is the best Datadog alternative?

Grafana + Prometheus is the best Datadog alternative for teams willing to self-host. It is completely free, open-source, and handles metrics, logs, and traces. For a managed solution, New Relic offers 100GB/month free ingestion with full-stack observability.

Q: Why do people switch from Datadog?

The number one reason is cost. Datadog bills can grow from hundreds to tens of thousands per month as infrastructure scales. Per-host pricing, custom metrics charges, and log ingestion costs create unpredictable bills that surprise many teams.

Q: Is Grafana better than Datadog?

Grafana is free and open-source with no per-host pricing, making it dramatically cheaper at scale. Datadog offers a more polished all-in-one experience with less operational overhead. Grafana wins on cost, Datadog on convenience.

The best Datadog alternative for most teams is Grafana + Prometheusbecause it's completely free and open-source, eliminates per-host and per-metric pricing surprises, and provides metrics, logs (via Loki), and traces (via Tempo) — the same pillars Datadog charges thousands for at scale.

Why People Switch from Datadog

1. Unpredictable costs. Datadog's per-host pricing ($15-23/host/mo for infra), custom metrics charges ($0.05/metric), and log ingestion costs ($0.10/GB) create bills that balloon as you scale. Teams report 10x cost increases year-over-year.

2. Vendor lock-in. Datadog uses proprietary agents, query languages, and dashboards. Migrating away requires rebuilding everything. Open-source alternatives use standard formats (PromQL, OpenTelemetry).

3. Feature bundling. Datadog charges separately for infrastructure monitoring, APM, logs, synthetics, and RUM. Competitors like New Relic include everything in one price.
