The short version

  • Each has a real cost: Arize AI the free plan caps trace spans at 25,000 per month with only 15 days of retention.; Fivetran billed on monthly active rows, so the bill tracks how much source data changes rather than how much is stored or queried
  • They diverge on capability: Arize AI covers End-to-end tracing, Fivetran covers Automated data pipeline.

Where each one falls short

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

Arize AI

  • The free plan caps trace spans at 25,000 per month with only 15 days of retention.
  • Self-hosted deployment and Data Fabric integration are restricted to the custom-priced Enterprise tier.
  • Pricing beyond the $50/month Pro plan requires a custom quote, making cost planning less transparent at scale.
  • Advanced compliance features like HIPAA are only available on Enterprise.

Fivetran

  • Billed on monthly active rows, so the bill tracks how much source data changes rather than how much is stored or queried
  • Each connection follows its own cost curve, so total spend is hard to predict before running a pipeline
  • The free plan allows 500,000 monthly active rows, 3,500 activation rows and 5,000 model runs
  • Transformations are metered separately, from $0.01 per model run above 5,000 down to $0.002 above 100,000
  • A schema change upstream that touches many rows raises the bill without any change on the customer's side
