The short version
- Only Comet ML has a free tier, so it costs nothing to try first.
- Each has a real cost: Comet ML the free cloud tier caps data at 25,000 spans a month with 60 day retention; Labster customization is limited and labs cannot be easily adapted to specific course learning outcomes
- They diverge on capability: Comet ML covers Experiment tracking, Labster covers Virtual simulations.
Where they differ
Only the attributes on which Comet ML and Labster actually diverge.
Identical on both: user rating (Not yet rated).

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
Labster
- Customization is limited and labs cannot be easily adapted to specific course learning outcomes
- Simulations can lag or freeze depending on operating system and connection speed
- Cannot fully replace hands-on physical lab experience and data collection
- Students report preference for tactile physical lab experience over virtual simulations
