Datadog is the most comprehensive observability platform on the market — and one of the most notorious for surprise bills. Because it’s priced per host and per module, costs add up fast. This guide breaks down Datadog pricing in 2026 so you can budget accurately.
The core thing to know: Datadog isn’t one price. You pay separately for Infrastructure, APM, Logs, and dozens of other modules, each with its own meter.
Datadog Pricing Overview (2026)
| Product | Price (annual) | Billing Unit |
|---|---|---|
| Infrastructure (Pro) | $15/host/month | Per host |
| Infrastructure (Enterprise) | $23/host/month | Per host |
| APM | $31/host/month | Per host |
| Log Management | $0.10/GB ingested | Per GB |
On-demand (monthly) billing costs more: Infrastructure Pro is $18/host and Enterprise $27/host without an annual commitment.
Infrastructure Monitoring
This is the foundation most teams start with:
- Pro ($15/host/mo annual): 100 custom metrics per host, 15-month metric retention, alerting, and dashboards.
- Enterprise ($23/host/mo annual): 200 custom metrics per host, advanced features, and tighter controls.
Hosts are counted hourly, so autoscaling environments can spike your effective host count — and your bill.
APM (Application Performance Monitoring)
APM is billed separately at $31/host/month (annual), with Pro and Enterprise tiers at $35 and $40. If you want both infrastructure and APM on the same hosts, you’re stacking two meters — a common source of bill shock.
Log Management
Logs are billed by ingestion and retention at roughly $0.10/GB ingested, plus indexing costs. High-volume logging is frequently the single largest line item on a Datadog invoice.
Why Datadog Bills Surprise Teams
- Per-host counting spikes with autoscaling and ephemeral containers
- Module stacking — Infrastructure + APM + Logs + Synthetics adds up quickly
- Custom metrics overages beyond the included allotment
- On-demand vs committed — month-to-month usage costs 20%+ more
To control spend: commit to an annual host count (discounts start around 25%), cap custom metrics, and use log filtering/sampling before ingestion.
How to Reduce Datadog Costs
- Right-size your committed host count instead of paying on-demand
- Drop or sample noisy logs before they’re ingested
- Audit unused modules and dashboards quarterly
- Consider focused alternatives for smaller stacks — see our best Sentry alternatives guide for error-monitoring options

Datadog vs Sentry on Price
| Datadog | Sentry | |
|---|---|---|
| Model | Per host + module | Per plan + events |
| Free tier | 14-day trial | Yes (5k errors) |
| Best for | Full-stack observability | Error & performance monitoring |
Sentry is cheaper and simpler for error tracking; Datadog is the broader platform when you need infrastructure, APM, and logs together. See the full Sentry vs Datadog comparison.
Verdict
Datadog’s pricing is powerful but complex. At $15/host/month for infrastructure it looks affordable, but the real cost comes from stacking APM, logs, and custom metrics across a growing host count. Commit annually, watch your modules, and filter logs aggressively — that’s the difference between a predictable bill and a shocking one.
Frequently Asked Questions
How much does Datadog cost per host?
Infrastructure monitoring starts at $15/host/month (Pro, annual) and $23/host/month (Enterprise). APM adds $31/host/month separately.
Why is Datadog so expensive?
Datadog bills per host and per module. Stacking Infrastructure, APM, and Logs across many hosts — plus custom metrics overages — drives bills up quickly.
Does Datadog have a free plan?
Datadog offers a 14-day free trial rather than a permanent free tier. For free error monitoring, consider Sentry’s Developer plan.
