Sentry vs Datadog is a common decision for engineering teams setting up monitoring in 2026. They overlap, but they’re built for different jobs: Sentry is laser-focused on application errors and performance, while Datadog is a sprawling full-stack observability platform. This guide helps you pick the right one.
Quick Verdict
- Choose Sentry if your priority is application error tracking and performance, especially for small to mid-sized teams that want predictable, affordable pricing.
- Choose Datadog if you need full-stack observability — infrastructure, APM, logs, and synthetics — across a large, complex environment.
Pricing Compared
| Sentry | Datadog | |
|---|---|---|
| Model | Per plan + event volume | Per host + per module |
| Free tier | Yes (5k errors/mo) | 14-day trial only |
| Entry price | $26/mo (Team) | $15/host/mo (Infra Pro) |
| Cost predictability | Moderate | Low (modules stack) |
Sentry is far easier to budget for small teams. See the full Sentry pricing breakdown and Datadog pricing breakdown for the details.
What Each Does Best
Sentry excels at code-level visibility: error tracking, stack traces, source maps, release health, session replay, and performance monitoring. It’s developer-first and quick to set up. Read our Sentry review for the full feature list.
Datadog is a unified observability suite: infrastructure metrics, APM, log management, synthetics, RUM, and security monitoring all in one platform. It’s built for SREs and platform teams managing large fleets. See our Datadog review for more.
Feature Comparison
| Feature | Sentry | Datadog |
|---|---|---|
| Error tracking | ★ Best in class | Good |
| Performance monitoring | Strong | Strong |
| Infrastructure monitoring | No | ★ Excellent |
| Log management | Limited | ★ Excellent |
| Setup complexity | Low | High |
| Free tier | Yes | No |
Which Should You Choose?
- Small/mid teams, app-focused → Sentry. Cheaper, simpler, with a real free tier.
- Large orgs, full-stack ops → Datadog. The breadth justifies the cost and complexity.
- Tight budget → Sentry’s free Developer plan is hard to beat.
- Many of you use both — Sentry for errors, Datadog for infrastructure — which is a legitimate combo.
Verdict
These tools aren’t really rivals so much as different layers of the stack. If you mainly need to catch and fix application errors, Sentry is the better, cheaper, simpler choice. If you’re running complex infrastructure and need everything in one observability pane, Datadog earns its premium. Match the tool to your team’s size and scope.
