Datadog vs Grafana
Datadog is the all-in-one monitoring platform where everything works together out of the box. Grafana is the open-source visualization layer that pairs with Prometheus, Loki, and other data sources. One costs real money. The other costs real effort.

Datadog
All-in-one monitoring platform with metrics, logs, traces, and more
Strengths
- +Everything in one place - metrics, logs, traces, APM, RUM
- +Setup is fast - install the agent and data starts flowing
- +Correlated views across infrastructure, apps, and logs
Weaknesses
- -Bills can spiral fast - $15/host is just the start
- -Log ingestion costs are notoriously high at scale
- -Custom metrics pricing catches people off guard
Best for
Teams that want unified monitoring without stitching tools together, and have the budget to pay for convenience at scale.
Grafana
Open-source visualization and monitoring you can self-host
Strengths
- +Free and open source - no per-host pricing
- +Works with any data source - Prometheus, InfluxDB, Elasticsearch, and more
- +Self-hostable with full control over your data
Weaknesses
- -Self-hosting means managing Prometheus, Loki, Tempo, etc. yourself
- -Stitching together the full stack (metrics + logs + traces) takes work
- -Alerting is less polished than Datadog's unified experience
Best for
Engineering teams comfortable with open-source tooling who want to avoid vendor lock-in and per-host pricing at scale.
Feature Comparison
| Feature | ||
|---|---|---|
| Price | $15/host/mo (Infrastructure) | Free (open source) |
| Metrics | Built-in, per-host pricing | Via Prometheus, Mimir, or other sources |
| Logs | Built-in, per-GB pricing | Via Loki (free, self-hosted) |
| Traces / APM | Built-in APM product | Via Tempo (free, self-hosted) |
| Dashboards | Yes, drag-and-drop | Yes, powerful and flexible |
| Alerting | Unified across all data | Yes, per data source |
| Integrations | 700+ out-of-box integrations | 80+ data source plugins |
| Self-hosting | No | Yes |
| Setup time | Minutes - install agent, done | Hours to days for full stack |
| Vendor lock-in | High | Low - swap data sources freely |
| Scaling cost | Linear - more hosts = more cost | Infrastructure cost only |
| Session replay / RUM | Yes, built-in | Limited (via plugins) |
The Verdict
At 10 hosts, Datadog is convenient and the bill is manageable. At 100 hosts with logs and APM, the invoice starts to sting. At 1,000 hosts, you'll wish you'd invested in Grafana earlier. The Grafana + Prometheus + Loki stack gives you the same observability capabilities for the cost of running the infrastructure. The tradeoff is setup time and operational complexity. If you have a small team and no dedicated platform engineers, Datadog's ease of use is worth paying for. If you have the engineering capacity and plan to scale, building on Grafana's open-source stack will save you serious money long-term.
