Comet vs Grain FAQ

- They both start at the same price — $19/mo. The difference is in what you get at each tier.
- Can I use either one for free?
- Both offer free plans, so you can try each without paying. Start with whichever fits your workflow better and upgrade when you hit the limits.

- Depends on what you need. Comet: At $19/mo for Pro, Comet undercuts most enterprise-first MLOps and LLM observability tools that gate everything behind a sales call — this is a land-and-expand play aimed at developers and small teams who'd otherwise bounce off a 'contact us' wall.
