Enterprise users find Data Hub affordable and effective, connecting multiple data sources with a $100,000 budget, with favorable feedback.
I found it easy to understand the pricing and subscription models for faster integration.
Senior Data Scientist at Evolvision Technologies
My experience with pricing, setup cost, and licensing is that I am using Perplexity, the pro version, which is connected to Comet, and together they provide me with very good results at a cost of only twenty dollars, which is acceptable to me.
Automation Engineer at a tech services company with 501-1,000 employees
Regarding experience with pricing, setup cost, and licensing, I think if we have a budget of one hundred thousand US dollars, we will be able to deploy a reasonable version and connect to a number of data sources.
Director at a university with 1-10 employees
It costs about zero since, if we win the setup, it probably results in no cost.

Organizing research experiments has improved and supports faster model comparison and learning
My experience with Comet has been very positive, but there are a few areas where it could be improved. One area is the learning curve for new users. Some of the more advanced features can feel overwhelming at first, especially for students who are new to machine learning experiment tracking. More beginner-friendly tutorials and guided onboarding would help. I would also like to see more customization options for dashboards and visualizations, making it easier to create views tailored to specific projects. Another improvement would be deeper integration with commonly used collaboration tools, which would streamline project documentation and team workflows. There are a few additional areas where Comet could improve. From a performance perspective, I occasionally notice that dashboards with a large number of experiments can take longer to load or navigate. Regarding documentation, while the available resources are helpful, I would appreciate more beginner-focused examples, step-by-step tutorials, and real-world use cases. For support, my experience has generally been good, but having more community resources, discussion forums, webinars, or educational content specifically aimed at students and researchers would be valuable.

Metadata management has streamlined lineage tracking and data discovery for our teams
The best features Data Hub offers include its integration capability with many popular tools like Apache Airflow, Snowflake, dbt, Looker, Apache Kafka, and BigQuery. These tools provide us with data in various places, and we commonly use Apache Airflow for the DAG, while utilizing BigQuery as our database and Apache Kafka for consuming messaging queues. Data Hub easily connects with all these tools and features excellent data discovery and visualization capabilities. We can see data visibility, where it comes from, its upstream and downstream relationships. If we remove a column, we can assess the impact of that change. Furthermore, if there are duplicate datasets being used by different teams that do not communicate regularly, onboarding all data to Data Hub allows us to identify these duplicates easily. Out of all those features, I believe data discovery and impact analysis are the most valuable for my team because when we want to add or drop a column, we can assess the impact analysis to understand the downstream effects. This helps us know who owns a dataset, and we can easily contact the owner. Tracking the data lineage back to the source table is also a key benefit. Data Hub has positively impacted my organization by significantly reducing manual work that was previously needed to identify upstream and downstream data relationships, as well as recognizing duplicate datasets. If a data contract is broken, we now easily get notified of those issues, making the process much easier and more efficient. It is particularly useful for data engineers and platform teams to check for problems directly within Data Hub. Data Hub has saved our team a lot of time. For example, in a large company like Porch, if I want to know whether a specific dataset exists, I can check Data Hub, as it serves as a centralized point for managing the metadata of our data. While it does not contain all data, it does contain the metadata necessary for understanding the dataset's origin. If a dataset does not exist, I can simply see who the owner is and reach out to them, which reduces the dependency on others by providing direct access to information in Data Hub.
