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; Khan Academy the Internet Archive's capture of Khan Academy's homepage on 1 January 2021 stated it is a 501(c)(3) nonprofit and that its full library of practice and lessons 'is all free for learners and teachers', funded by donations rather than subscriptions.
- They diverge on capability: Comet ML covers Experiment tracking, Khan Academy covers Video lessons.

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
Khan Academy
- The Internet Archive's capture of Khan Academy's homepage on 1 January 2021 stated it is a 501(c)(3) nonprofit and that its full library of practice and lessons 'is all free for learners and teachers', funded by donations rather than subscriptions.
