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

Vector

  • Free and open source under the MPL-2.0 license, backed by an open source community with a public GitHub repo
