Pricing Overview
Datadog uses a usage-based pricing model that charges separately for each observability product. Infrastructure monitoring starts at $15/host/month for the Pro plan and $23/host/month for the Enterprise plan on annual billing. APM pricing ranges from $31/host/month to $40/host/month depending on the plan selected. Log management charges $0.10/GB for ingestion and $1.70 per million events for indexing at 15-day retention. Custom metrics are billed based on unique metric-and-tag combinations per hour, with overages at $0.10 per 100 metrics beyond your allocation. Datadog also offers a free tier that includes up to 5 hosts with core infrastructure monitoring, making it accessible for small teams evaluating the platform before committing to paid plans.
Plan Comparison
Datadog structures its pricing around individual product modules, each with its own tiers. The table below shows the primary products and their per-unit costs on annual billing.
| Product | Pro Plan | Enterprise Plan | Billing Unit |
|---|---|---|---|
| Infrastructure Monitoring | $15/month | $23/month | Per host |
| APM | $31/month | $40/month | Per host |
| Log Management (Ingestion) | $0.10 | $0.10 | Per GB |
| Log Management (Indexing) | $1.70 | $1.70 | Per million events (15-day retention) |
| Custom Metrics | $0.10 per 100 | $0.10 per 100 | Per metric beyond allocation |
| Synthetic Monitoring | $5.00 | $12.00 | Per 10K test runs |
| Real User Monitoring | $1.50 | $1.80 | Per 1K sessions |
Each product is billed independently, and costs stack as you enable additional modules. The free tier covers up to 5 hosts for infrastructure monitoring with 1-day metric retention. Pro plans extend retention and add alerting features, while Enterprise includes advanced capabilities like live processes, anomaly detection, and compliance-grade audit trails.
Hidden Costs and Considerations
Datadog's multi-dimensional pricing creates several cost traps that are easy to overlook. Custom metrics are the most common source of bill shock: each unique combination of a metric name and its tag values counts as a separate billable metric, so adding a high-cardinality tag like user ID or region multiplies your metric volume by every unique value. In Kubernetes environments with ephemeral pods, host counts can spike unpredictably. Log indexing costs compound quickly at high volumes, and retention beyond 15 days incurs additional charges. Multi-year and volume discount contracts are available but require upfront commitment.
Cost Estimates by Team Size
Based on Datadog's published per-unit pricing, here are realistic monthly cost estimates for teams running infrastructure monitoring and APM together on the Pro plan.
| Team Size | Hosts | Estimated Monthly Cost | What's Included |
|---|---|---|---|
| Startup (5 engineers) | 10-20 hosts | $460-$920 | Infrastructure + APM (Pro) |
| Mid-size (20 engineers) | 50-100 hosts | $2,300-$4,600 | Infrastructure + APM (Pro) |
| Enterprise (50+ engineers) | 200-500 hosts | $9,200-$23,000 | Infrastructure + APM (Pro) |
These estimates cover infrastructure monitoring at $15/host/month and APM at $31/host/month only. Adding log management, synthetic monitoring, RUM, or custom metrics will increase costs. Enterprise plan pricing ($23 + $40 per host) pushes estimates 35-40% higher across all tiers.
How Datadog Pricing Compares
Datadog's per-host pricing places it at the premium end of the observability market. Competitors offer distinct pricing approaches that can result in significant savings depending on your infrastructure size and data volume.
| Platform | Pricing Model | Starting Price | Key Difference |
|---|---|---|---|
| Datadog | Per host + usage | $15/host/month (Pro) | Separate charges per product module |
| New Relic | Usage-based | $19/host/month | Free tier with 100 GB/month data ingest |
| Observe | Usage-based | $0.49/GB (logs) | Pure consumption-based, no per-host fees |
| Elastic Observability | Tiered subscription | $95/month (Standard) | Flat monthly tiers, self-hosted option available |
New Relic offers a comparable feature set at $19/host/month with a generous free tier that includes 100 GB of monthly data ingestion. Observe takes a pure consumption approach starting at $0.49/GB for logs, which benefits teams with fewer hosts but high data volumes. Elastic Observability uses flat monthly tiers starting at $95/month for the Standard plan, $125/month for Platinum, and $175/month for Enterprise, providing more predictable costs for teams that want to avoid per-host billing entirely. For organizations running 50+ hosts with multiple Datadog products enabled, the annual spend difference between Datadog and alternatives can reach tens of thousands of dollars.
