Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Cline
- no seat licenses or subscription fees for open source tier creates unclear Enterprise pricing model
- JetBrains IDE support only in Enterprise tier
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
