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
Udemy
- Course quality varies significantly as Udemy allows anyone to create and sell courses without vetting
- No formal credentials or degrees offered, unlike Coursera and edX which offer institution-branded certificates
- Courses are self-paced with no instructor interaction or support, making structured learning difficult for some students
