Comet ML
Software
Platform for tracking, comparing, and optimizing ML experiments
- From
- Free
- Rated
- -
The short version
- Each has a real cost: Comet ML the free cloud tier caps data at 25,000 spans a month with 60 day retention; Metabase row and column level permissions and SSO available only in Pro tier and above
- They diverge on capability: Comet ML covers Experiment tracking, Metabase covers No-code Query Builder.
Where they differ
Only the attributes on which Comet ML and Metabase actually diverge.
Identical on both: starting price (Free), free tier (Yes), user rating (Not yet rated), category (Unknown).

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
