What it is
MLJAR AutoML automates supervised machine learning for tabular data, including binary classification, multiclass classification, and regression. Users can work through MLJAR Studio notebooks or use the open-source Python package in scripts and notebooks. Its four modes—Explain, Perform, Compete, and Optuna—have configurable choices for algorithms, validation, metrics, time budget, and explanations. Depending on the selected mode and settings, workflows can preprocess data, select and tune models, engineer and select features, and create ensembles. Experiments include model comparisons, validation results, training times, explanations, and reusable artifacts; summaries are available in Markdown and JSON. Fairness-aware training evaluates models against a chosen metric and threshold and can try sample reweighting, but does not guarantee fairness. The Python package integrates with Mercury for prediction apps supporting individual and batch CSV predictions; apps can be previewed locally, published through MLJAR Platform, or self-hosted with Docker. The package is open source under the MIT license and costs nothing. AutoML is designed for supervised tabular tasks, and reports depend on task and settings.

Plans and prices
Strong points and limits
Strong points
- MIT-licensed Python package costs nothing
- Offers four configurable training modes
- Reports can include comparisons, validation, and explanations
- Mercury apps support single and batch CSV predictions
Limits
- Designed for supervised tabular tasks
- Does not support forecasting workflows or time-series modeling
- Fairness-aware training does not guarantee a fair model
Who it suits
MLJAR AutoML suits users building supervised models for tabular classification or regression who want configurable training modes and experiment reports. It also suits Python users who want to create prediction apps with Mercury and deploy them locally, through MLJAR Platform, or with Docker.
Verdict
MLJAR AutoML provides a free, open-source route to supervised tabular model training and configurable experiment workflows. Reports and explanations vary with the task and settings, and fairness mitigation is not a guarantee.
