Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Buildah

  • Linux only, with no native macOS or Windows support
  • Scriptable builds are powerful but less portable and less familiar than a Dockerfile
  • Narrow by design: it builds images and does not run them, so it needs Podman or another runtime alongside

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
