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; Drizzle ORM it is entirely community/sponsor-funded with no official paid support tier for enterprises needing SLAs.
- They diverge on capability: Comet ML covers Experiment tracking, Drizzle ORM covers Type-safe query builder.

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
Drizzle ORM
- It is entirely community/sponsor-funded with no official paid support tier for enterprises needing SLAs.
- The relational query API is newer than the SQL-like API and has historically had fewer advanced features.
- Documentation and ecosystem tooling are less mature than Prisma's, which has a larger community and GUI ecosystem.
- MSSQL and CockroachCB support are newer additions still stabilizing toward a 1.0 release.
