15 Best Tools for Tracking Machine Learning Experiments
While working on a machine learning project, getting good results from a single model-training run is one thing, but keeping all of your machine learning experiments organized and having a process that lets you draw valid conclusions from them is quite another. That’s what machine learning experiment management helps with.
In this article, I will explain why you, as data scientists and machine learning engineers, need a tool for tracking machine learning experiments and what is the best software you can use for that.
Tools for tracking machine learning experiments - who needs them and why?
- Data Scientists: In many organizations, machine learning engineers and data scientists tend to work alone. That makes some people think that keeping track of their experimentation process is not that important as long as they can deliver that one last model. This is true to an extent, but when you want to come back to an idea, re-run a model from a couple of months ago or simply compare and visualize the differences between runs, the need for a system or tool for tracking ML experiments becomes (painfully) apparent.
- Teams of Data Scientists: A specialized tool for tracking ML experiments is even more useful for the whole team of data scientists. It allows them to see what others are doing, share the ideas and insights, store experiment metadata, retrieve it at any time and analyze it whenever they need to. It makes the teamwork much more efficient, prevents situations where several people work on the same task, and makes onboarding of new members way easier.
- Managers/Business people: tracking software creates an opportunity to involve other team members like managers or business stakeholder in your machine learning projects. Thanks to the possibility to prepare visualizations, add comments and share the work, managers and co-workers can easily track the progress and cooperate with the machine learning team.

“Every experiment is sacred…” as they say in the Sacred tool description. Sacred is open-source software and allows machine learning engineers to configure, organize, log and reproduce experiments. Sacred doesn’t come with its proper UI but there are a few dashboarding tools that you can connect to it, such as Omniboard, Sacredboard or Neptune. Also, it doesn’t have the scalability of previous tools and has not been adapted to team collaboration, however, it has great potential when it comes to individual research.
- Open-source tool
- Extensive experiment parameters customization options
- Easy integration
See the comparison between Sacred + Omniboard and Neptune.
MLflow is an open-source platform that helps manage the whole machine learning lifecycle. This includes experimentation, but also reproducibility and deployment.

That means a data scientist who works with MLflow is able to track an experiment, organize it, describe it for other ML engineers and pack it into a machine learning model. It’s been designed to enable scalability from one person to big organization, however, it works best for an individual user.
- Focus on the whole lifecycle of the machine learning process
- Compatible with many additional tools and platforms
- Open interface integrated with any ML library or language
See the comparison between MLflow and Neptune.
- Large library of pre-built tracking tools
- Integration with many other tools and applications
- Well prepared problem-solving materials and community
See the comparison between TensorBoard and Neptune.
The team behind guild.ai states that “The faster and more effective you can apply experiments, the sooner you’ll complete your work.” In order to make this process well organized they created this open-source experiment tracking software, which is best suited for individual projects. It’s lightweight and equipped with many useful features that make it easier to run, analyze, optimize and recreate machine learning experiments. What’s more, guild.ai includes a variety of analytics tools making the experiments comparison process much easier.

It focuses on data and pipeline versioning and management but has some (limited) experiment tracking functionalities. It can be easily used with other tools on this list as a complementary tool.
- Adaptable to any language and framework
- Possibility to version large amount of data
- Open-source character
See the comparison between DVC and Neptune.
Tracking machine learning experiments has always been an important element of the ML development process, however, in the past, it required a lot of effort from data scientists. The tracking tools were limited and thus the process was manual and time-consuming.
For this reason, data scientists and engineers often neglected this part of the machine learning lifecycle or created home-grown solutions. It shouldn’t be the case anymore.
Over the last few years, tools for tracking machine learning experiments have matured a lot and are extremely accessible and easy to use. The apps and platforms we listed today are the best examples. Hopefully, every data scientist finds here the software that will make his or her life easier!
