The short version

  • Only Sentry has a free tier, so it costs nothing to try first.
  • Each has a real cost: etcd licensed under Apache License 2.0 per the project's GitHub repository (etcd-io/etcd LICENSE); as open source software it has no paid tier or vendor price to compare; Sentry spending caps stop event ingestion when reached, eliminating visibility during critical moments

Where each one falls short

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

etcd

  • Licensed under Apache License 2.0 per the project's GitHub repository (etcd-io/etcd LICENSE); as open source software it has no paid tier or vendor price to compare
  • Benchmarked at only thousands of writes per second per instance per etcd.io, a throughput ceiling that requires clustering or an alternative store for higher write volumes

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
