- Each has a real cost: Datadog consumption-based pricing model makes costs hard to predict and can scale quickly; Sentry spending caps stop event ingestion when reached, eliminating visibility during critical moments
- They diverge on capability: Datadog covers Infrastructure monitoring, Sentry covers Error tracking.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Datadog
- Consumption-based pricing model makes costs hard to predict and can scale quickly
- Add-on modules significantly increase costs: custom metrics, indexed spans, extended retention
- No free tier for production monitoring
- High costs for organizations with large amounts of log data or high-cardinality metrics
Sentry
- Spending caps stop event ingestion when reached, eliminating visibility during critical moments
- Complex configuration required for filters, sampling rules, issue grouping, and alert policies
- Difficult to configure custom alerts and alert content without creating email inbox bloat
- Error grouping is imperfect with noise and filtering issues causing incorrect error prioritization
- Weak for distributed tracing across microservices compared to dedicated APM tools
- UI dashboard is less customizable than alternatives like Datadog APM for complex monitoring needs
