Where each one falls short

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

Rollbar

  • The free plan allows 5,000 occurrences a month with 30 day retention
  • Retention is a paid ladder rather than a setting, at up to 90 days on Essentials and up to 180 on Advanced
  • Advanced alerting, the RQL analytics query language and SCIM provisioning are excluded from the free plan
  • Enterprise requires a $4M annual plan minimum
  • No price is published for Essentials or Advanced, so only the free tier has a visible cost

Splunk Cloud

  • Significantly higher pricing than competitors like Datadog and Elastic
  • Per-GB ingest costs of $150+/day make budget forecasting difficult
  • Extended retention adds substantial additional costs
  • Enterprise Security add-on costs $25-45/GB/day on top of base pricing
