Review provided by G2
What do you like best about the product?
It is very easy to setup you can setup it in very few lines of code and you can autolog in a minute it work across many python ml libraries like skitlearn and the code environment and parameter are saved automatically saved after one run of ml model.
What do you dislike about the product?
It is mainly python centric it supports less other languages like ruby kotlin and java and the cost of team and enterprise edition camn get very expensive as compared to any open source option like github.
What problems is the product solving and how is that benefiting you?
Building an ml in this day to day life is not same as writing normal software, the same code give same output but in ml the result depends upon the code , data which you upload what setting you setup some randomness and depends upon which environment you are working and you can change all of these constantly while experimenting the ai but when we use this comet ml platform, it make a proper environment for a team so it has same data setting in an environment which improves the quality of ml model as compared to a normal software

Great for Team Model Collaboration, but Pricing and Credit Usage Are Hard to Predict
Reviewed on Oct 08, 2026
Review provided by G2
What do you like best about the product?
The best part is when we build a model in a team, it helps us check which team member is working on which part of the model, reducing time and duplication.
What do you dislike about the product?
The most disliked part of this software/platform is that we can't predict the price and the amount of credits that will be used on a project, leading to high usage and platform fees that are not easily affordable by a normal organization.
What problems is the product solving and how is that benefiting you?
When working on traditional software to create a model like GitHub, we can't identify which part of the work is being done by which member, leading to long hours and reducing our team's potential. Comet ML solves the problem of duplication among team members.

Great for Tracking and Optimizing ML/LLM Experiments, But Costs Scale with Usage
Reviewed on Oct 07, 2026
Review provided by G2
What do you like best about the product?
It helps us in data science projects to track, compare, visualize, and optimize machine learning experiments and LLM workflows in one place, and you can integrate Comet into your training script by adding just a few lines of code.
What do you dislike about the product?
It has paid tiers and usage fees in billing, such as extra usage of Opik or per user seat licenses, which increase the cost to use it and rise with an increase in team members and growing data.
What problems is the product solving and how is that benefiting you?
In engineering teams, team members often work individually on their local machines without a centralized hub, causing duplication of work when two members do the same task, leading to time loss. However, when we use Comet.ml, it helps team members track who is working on which project and then work accordingly.

Comet Keeps Every Serious Run—Metrics, Parameters, and Context—in One Place
Reviewed on Oct 02, 2026
Review provided by G2
What do you like best about the product?
Before Comet, the “best” model lived in someone’s memory or an old notebook name. What I like is that every serious run leaves a record—metrics, parameters, and context—in one place, so we can find what actually worked instead of re-running guesses. Comparing a few candidates takes minutes, and handing a result to someone else does not depend on them recreating my local setup.
What do you dislike about the product?
If the team logs inconsistently, the workspace gets noisy. You still need light discipline on what to track and how to name projects. It will not fix a messy process by itself.
What problems is the product solving and how is that benefiting you?
It solves the lost-experiment problem: results scattered across machines and chat threads. The benefit is faster decisions and less repeated work, because we can see prior runs and build on them instead of starting from scratch each time.

Comet.ml Makes Experiment Tracking Effortless with Clear Dashboards
Reviewed on Sep 01, 2026
Review provided by G2
What do you like best about the product?
The best thing about Comet.ml is that it takes a lot of the manual effort out of experiment tracking. It's easy to see how different model runs performed, and the dashboards make it simple to spot trends without digging through logs. It has definitely helped make my workflow more organized. The automatic logging of metrics, parameters, and training runs has also made it much easier to compare experiments
What do you dislike about the product?
Although Comet integrates with major frameworks like PyTorch and TensorFlow, highly customized ML pipelines actually require additional logging and instrumentation work which is not good
What problems is the product solving and how is that benefiting you?
Since my work involves People Consulting, competency frameworks, working with large datasets of JDs/ competencies, using comet helps me in bringing more structure to this process as I can track experiments and their results in 1 place instead of relying on scattered files or notes or manually maintained records.
The biggest benefit is visibility and reduction of time spent manually.

What do you like best about the product?
I really like that Comet.ml allows me to track experiment metrics, parameters, model versions, and training outputs all in one place. When I make changes to features or model parameters, comparing runs becomes easy-eliminating the need to take separate notes or maintain spreadsheets. The dashboard also lets me see at a glance which experiment is performing better.
What do you dislike about the product?
The platform is packed with features. Because of this, I initially found the user interface a bit cluttered. It can take some time to learn how to organize logging effectively, and setting things up for large projects might also require some time.
What problems is the product solving and how is that benefiting you?
Avoid losing track of your machine learning experiments with Comet.ml. We often test multiple models, datasets, and hyperparameters simultaneously. Comet.ml enables us to keep a record of what was changed and the resulting output, allowing for quick and efficient model comparisons. It is also excellent for collaboration, as others can see previous experiments without any extra effort.
