Sentry vs Datadog
This is a scope question, not a feature-by-feature fight. Sentry is a focused error & performance tracker. Datadog is a full APM and observability platform where error tracking is one module among many. The right answer depends on how much of your stack you want in one pane of glass.
The short version
If you want error tracking done well, close to your code and releases, Sentry (or a lighter tool like GlitchTip) is more focused and far cheaper. If you're already running infrastructure metrics, logs and distributed traces and want errors folded into that same platform, Datadog makes sense — accepting that it's a bigger, pricier commitment.
How they compare
| Sentry | Datadog | |
|---|---|---|
| Category | Error & perf tracking | Full APM / observability suite |
| Error tracking depth | Best-in-class, code-level | Good, part of a broader suite |
| Infra metrics / logs | Logs (newer, metered) | Extensive |
| Distributed tracing | Yes | Extensive |
| Free tier | 5k errors/mo | Limited free / trial |
| Pricing | ~$26/mo entry | Per-host + per-product, adds up fast |
| Self-host | Yes (40+ containers) | No |
| Best for | Dev teams focused on app errors | Ops/SRE wanting one platform |
When Sentry wins
- Error tracking is the job. You want deep, code-level errors, releases and performance without buying a whole observability suite.
- Cost control. Datadog's per-host, per-product pricing gets expensive quickly; a focused tracker is much cheaper.
- You're a development team, not an ops/SRE org running large infrastructure.
When Datadog wins
- You already run Datadog for infra metrics, logs and traces and want errors in the same pane.
- You need full-stack observability and correlation across services, hosts and pipelines.
- Budget is less of a constraint than consolidation onto one vendor.
A middle path
If you want full observability but not Datadog's bill, SigNoz (OpenTelemetry-native, self-hostable) gives you errors, traces and metrics in one open-source platform. And if you only need errors on a budget, the drop-in options — GlitchTip or Bugsink — are the cheapest route off Sentry. Whichever you pick, tag releases on every deploy automatically, for example via Buddy's Sentry action.
