The short answer

Sentry vs Datadog

Neither is better for everyone. Sentry suits teams that want error tracking with usage-based overage billing. Datadog suits teams running multiple hosts that want one platform across infrastructure, APM and logs; per-host pricing makes it harder to estimate for very small apps. They do different jobs, so this is less a head-to-head than a question of which job you need done.

Limits and things to check

Sentry

  • Pre-purchasing (reserved) volume is about 20 percent cheaper than pay-as-you-go, and unused reserved volume expires monthly.[5] One source only.
  • The free Developer plan is limited to one user and a 5k error quota.[1]

Datadog

  • Per a third-party summary, every billable APM host requires Pro or Enterprise Infrastructure Monitoring, so a traced host costs roughly $46 per month on the Pro path.[6] One source only.
