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
Manus
- Specific pricing and plan tiers not published on accessible pages; users must visit pricing page or contact sales
- Organisational transition mid-2026; unclear how this affects feature stability or pricing continuity
- No clear free tier mentioned; access requires subscription from apparent launch
- Limited public documentation on capabilities and limitations
