Comet ML plans, side by side
Every published tier in ascending order of price, with the number of features each one lists. An absence here means the record does not itemise it, not that the tier lacks it.
| Plan | Price | Features listed | Step up from the tier below |
|---|---|---|---|
| Free Cloud | Free | 4 | Entry tier |
| MLOps Free | Free | 5 | +$0/month, 5 more features |
| Pro Cloud | $19/month | 5 | +$19/month, 5 more features |
| MLOps Pro | $19/user/month | 5 | +$0/user/month, 5 more features |
What each tier adds
The set difference between each tier's feature list and the one beneath it. Where a tier lists nothing new, the vendor has either stopped repeating the inherited list or the tier raises limits rather than adding capability, the record does not distinguish the two, so this page does not either.

Before you pay for Comet ML
Three things this page cannot tell you, and all three change the bill. The record carries a price and a billing period but not the unit - per-seat and flat-rate pricing are indistinguishable in this data, so a five-person team may be looking at five times the figure above. It carries no annual rate, so any discount for paying yearly is not something this page can quote. And it carries no trial length.
What it can tell you is the shape of the ladder: 4 tiers between Free and $19/user/month, with the jump itemised above. Because there is a free tier, the cheapest way to answer the rest is to use it before paying anything.
Comet ML runs on web, linux, mac, windows, and is published by Comet ML of New York, New York. The full record is on the Comet ML review, and the rest of the category is under best machine learning tools.
Comet ML pricing questions

- Comet ML publishes 4 tiers, from Free for Free Cloud up to $19/user/month for MLOps Pro. The entry tier costs nothing.
- Does Comet ML have a free plan?

- What is the difference between Free Cloud and MLOps Free on Comet ML?
- MLOps Free costs Free against Free, and adds 1 user with fair usage policy, experiment tracking, dataset management, model registry.
- Is the MLOps Pro plan on Comet ML worth it?
- That depends entirely on whether you need what it adds, which on the published record is up to 10 users, 1,500 training hours included, 500gb storage included, $1 per additional training hour. It costs $19/user/month against $19/month for Pro Cloud. Softwr has not used either tier, so this page can tell you what changes, not whether it is worth the difference to you.
- Is Comet ML expensive for a machine learning tool?
- It starts below the middle of its category. Across the 3 machine learning tools in this directory that publish a starting price, the median entry point is $29/month; Comet ML starts at $19/month.
- Which machine learning tools can I use without paying?
- 7 of the 8 machine learning tools listed alongside Comet ML have a free tier: ClearML, Langwatch, Haystack, Semantic Kernel, H2O.ai.
- What am I actually paying for with Comet ML?
- The record lists 14 features across 3 areas: other, integrations, platform. In practice it is brought in for llm observability and monitoring, ai agent testing and debugging, experiment tracking for machine learning.
- Does Comet ML charge per user?
- The record carries a price and a billing period for each of its 4 tiers, but not the unit that price is charged in. Per-seat and flat-rate billing look identical in this data, so check the vendor's page before budgeting for a team.
