Model packaging and deployment
These tools support packaging and deployment and provide reproducibility.
1. KitOps
Working on an ML project requires many hands; more often than not, everyone works in isolation. While this process might ultimately lead to a great product or project, it introduces the issue of managing and keeping track of every component—data, code, configurations, artifacts, metadata, and ML model—used throughout the project’s lifecycle.
KitOps solves this problem by using a Kitfile to locate the components and ModelKit an OCI-compliant packaging format, to package your components into a single, standardized unit. ModelKit uses immutable OCI-standard artifact technologies similar to container-native technologies, making it tamper-proof.
In addition to packaging your components as a single unit, KitOps can version and unpack individual components. This tool also integrates with various tools and platforms, from Docker Hub to Azure ML and Comet ML. To further support this, KitOps provides a detailed list of tools compatible with ModelKit packages. This feature simplifies dependency management, streamlines workflows, and improves collaboration across development teams.
The key advantage of KitOps is that everything can be done via Kit CLI. To learn more about KitOps, check out their beginner-friendly documentation and start by building a Retrieval-Augmented Generation (RAG) pipeline.
2. MLflow
MLflow is an open source platform for managing the machine learning project lifecycle, from model development to deployment and performance evaluation. It is beneficial for several reasons.
MLflow makes reproducing results, deploying, and managing your models easy by tracking your ML experiments. The platform is also environment-agnostic and can be accessed via a REST API and Command Line Interface (CLI).
It has seven components:
- MLflow model registry is used to store your ML models. It comes with versioning and annotating capabilities.
- MLflow Tracking is used to track experiments and measure model performance.
- MLflow Models for deploying your ML projects across cloud platforms.
- MLflow projects are used to pack your projects to ensure reusability, reproducibility, and portability.
- MLflow Prompt Engineering UI handles your prompt engineering task.
- MLflow Deployments for LLMs offers APIs to access SaaS and OSS LLM models.
- MLflow Recipes for structuring ML projects for real-world deployment scenarios.
MLflow also integrates with various tools and platforms, from PyTorch and LangChain to HuggingFace, OpenAI, Keras, and TensorFlow. You can start building models and generative AI applications on MLflow by following this tutorial.
3. Streamlit
Streamlit is an open source platform that turns your Python scripts into shareable web apps in minutes with just a few lines of code. These interactive web apps are often the demo apps for most ML projects. The most fascinating thing about this platform is that it requires no front-end or back-end experience. Moreover, Streamlit lets you create these sites without HTML, CSS, or JavaScript, without defining routes and focusing on handling HTTP requests.
Streamlit also allows developers to build and deploy powerful generative AI apps in under a minute. Their tutorial pages cover various topics, from how to build an LLM app using LangChain and how to deploy applications in Streamlit.
4. Gradio
Like Streamlit, Gradio is an open source tool for sharing your ML models as web apps with the public. This tool creates an interactive interface for your model. This customizable interface supports integration with popular frameworks like PyTorch and Scikit-learn.
Besides creating a shareable link, Gradio allows developers to present and embed their model interface in Python notebooks to showcase their model capabilities. This link can be generated via a Pythonic API and supports multiple input types, from text to image, audio, and video.
You can build an ML model and share your first application with this Gradio tutorial.
5. RapidMiner
RapidMiner Studio is a software and data science platform for data analysts and ML engineers. It simplifies your project's data processing, mining, machine learning, and model deployment stages. Though this platform is mainly geared toward developing and deploying predictive analytics applications, it still offers users a wide variety of supervised, unsupervised, and reinforcement learning models.
Some features that make Rapid Miner appealing are its pre-built operators, drag-and-drop functionality, interactive visualization, collaborative environment, and visual programming interface, allowing users to create ML workflows without writing code.
The best way to learn how to use RapidMiner Studio is via the community tutorials.
Data and model versioning
These tools manage datasets, models, and code versioning for reliable tracking and reproducibility.
6. DVC (Data version control)
DVC can be described as the Git for your data science project. Data Version Control is a version control application that manages and tracks changes to data, ML models, and experiments. This way, you can keep your Git repository lightweight while ensuring your project can be reproduced at any point with the right data version. This is pretty similar to how Git tracks your code changes.
In addition to using Git for data versioning, DVC has local experiment tracking for ML experiment management and data pipeline versioning that helps describe how your data are built with other data and codes. The great thing about experiment tracking with DVC is that you don't have to leave Git to evaluate and visualize the metrics and parameters of your ML projects.
Start your DVC experience with a hands-on image classifier project, featuring both data and model versioning.
Pipeline and workflow orchestration
These tools automate complex workflows by optimizing your ML and data processes for scalable production.
7. Flyte
Flyte is an open source workflow orchestration platform that allows developers to build, transform, and deploy data and ML workflow through their Python SDK. This way, you can build and execute scalable, maintainable, reproducible pipelines for data processing and machine learning.

Apache SystemDS (Formerly Apache SystemML) is an end-to-end data science and ML system that manages your data science projects, from integration and data cleaning to model training and deployment. This platform, built by the Apache software foundation, aims to solve a simple issue.
Typically, models are developed and run on personal computers. While this is great for small datasets, it is unsuitable for large ones because they need more than one node and a more extensive distributed system.
SystemDS address this by offering a large-scale, declarative ML platform with distributed jobs capabilities on Apache Hadoop and Apache Spark. This declarative language is pretty similar to R and Python syntax. It can be compiled into hybrid execution plans of local and in-memory (CPU and GPU) operations.
You can explore Apache SystemDS by trying out some matrix operations from their quickstart guide to learn more.
11. Kedro
Kedro is an ML development framework that brings data science projects from pilot development to production by creating reproducible, maintainable, and modular data science code. Kedro has a data catalog for data handling, support pipeline building, and a standardized template for code maintainability and consistency to effectively do this. Its data catalog uses lightweight data connectors to manage and track datasets. This allows you to use the same pipeline to build multiple production-level codes across your system.
Besides versioning your dataset and automating your pipelines, Kedro comes with Kedro-Viz to help you visualize your data, ML workflows, experiments, and their connections.
