Comet vs MLflow

Finding MLflow Insufficient? Level Up Your MLOps Tooling with Comet!

MLflow is a great tool for teams who are just starting their ML journey. As teams start to deploy models in production, they require a scalable and secure tool like Comet that allows them to reproduce, debug,  govern, and monitor their models.

Trusted by the most innovative ML teams

Erica Green

ML Team Lead - Etsy

"It's one of the things that zero to anything is like night and day...We looked at all the options on the market and went with Comet."

Greig Cowan

Head Of Data Science - NatWest

"MLFlow was not well maintained, and compared to Comet, it didn’t have all the features needed to track experiments, especially as we started scaling."

Ashwin Bhide

ML Platform Engineer -Affirm

"With MLFlow we needed to take care of updates, backups and implement our own user management layer. Comet handles all of that and much more."

Model Monitoring

Monitor and manage models, from small teams to massive scale

Add two lines of code to your notebook or script and automatically start tracking code, hyperparameters, metrics, and more, so you can compare and reproduce training runs.

Experiment Management
PythonJavaR
1 from comet_ml import Experiment
2 
3 # Initialize the Comet logger
4 experiment = Experiment()

Comet’s ML platform gives you visibility into training runs and models so you can iterate faster.

Experiment Management

In addition to the 30+ built-in visualizations Comet provides, you can code your own visualizations using Plotly and Matplotlib.

Knowing what data was used to train a model is a key part of the MLOps lifecycle. Comet Artifacts allows you to track data by uploading directly to Comet’s machine learning platform or by storing a reference to it.

Comet Artifacts

Comet Model Registry allows you to keep track of your models ready for deployment. Thanks to the tight integration with Comet Experiment Management, you will have full lineage from training to production.

Comet Model Registry

The performance of models deployed to production degrade over time, either due to drift or data quality. Use Comet’s machine learning platform to identify drift and track accuracy metrics using baselines automatically pulled from training runs.

Comet Model Production Monitoring

Track your LLM prompts and responses in Comet to keep a single system of record for all your Prompt Engineering work. Add token metadata, benchmark the performance of different LLMs, and score prompt responses to find the best prompt templates for your specific use-cases!

Frequently Asked Questions

How difficult is it to switch from tracking experiments with MLflow to Comet?

Comet integrates with MLflow! MLflow users will have to change little to none in their training scripts to start logging data to Comet.

Is there a way to retroactively move all the data I have logged in MLflow to Comet?

Yes! We have built migration scripts to make this incredibly easy!

MLflow is open-source and free, why should I pay for a tool?

MLflow has well-known security vulnerabilities, lacks scalability, and has no dedicated support team to help you resolve issues. Fixing all these shortcoming would require a significant resource investment. It’s much easier and cheaper to choose a tool like Comet.
