Where each one falls short

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

Comet ML

  • The free cloud tier caps data at 25,000 spans a month with 60 day retention
  • Retention stays at 60 days even on the paid Pro plan, and extending it is a $29 per 100k spans add on
  • Overage on Pro is $5 per additional 100,000 spans
  • The free MLOps tier is a single user with 100 GB of storage and training hours governed by a fair usage policy
  • Pro MLOps is $19 per user per month and caps the team at 10 users

Metabase

  • Row and column level permissions and SSO available only in Pro tier and above
  • Advanced analytics features like multi-tenant embedded analytics require Pro tier or higher
  • AI-powered features incur additional usage-based costs: $3.75 per 1M tokens
  • Self-hosted deployment on Free/Open Source tier requires infrastructure management
