Overall Score
Based on our independent scoring across 6 dimensions, Sentry scores 89/100 overall versus Datadog APM's 86/100 — a 3-point margin. Sentry leads on Integrations in particular. That said, Datadog APM may still be the right choice if the dimensions where it scores higher match your specific priorities — the radar chart above shows the full profile side by side.
Both Sentry and Datadog APM offer a free tier, so entry-level cost is not a differentiating factor. Compare the feature and usage limits of each free plan to see which gives you more headroom before a paid upgrade is needed.
Sentry scores higher on Price / Value — 80/100 versus 55/100 for Datadog APM. If price / value is your primary decision criterion, Sentry is the stronger choice in this head-to-head.
Switching between error monitoring tools is generally possible but involves migration effort: exporting your data or configuration from Sentry, re-importing or reconfiguring in Datadog APM, and updating any API integrations or environment variables in your codebase. The effort scales with how deeply embedded the tool is in your stack. Test Datadog APM on a non-production project first before migrating.
Sentry (89/100) is the better fit for teams who prioritise integrations — its strongest dimension — and who want a free entry point. Datadog APM (86/100) is the better fit for teams who prioritise performance apm and want a free entry point. If both dimensions matter equally, the overall score winner (Sentry) is the safer default choice.
