Neptune is a commercial experiment tracking and model registry platform tailored for machine learning and deep learning teams. It enables centralized logging, visualization, and comparison of experiments and model metadata, helping users stay organized and maintain reproducibility across complex ML workflows.

Geared toward researchers, ML engineers, and MLOps practitioners, Neptune focuses on streamlining the collaboration and documentation process for model development at scale. Unlike pipeline orchestration tools, Neptune is purpose-built for experiment-level tracking, making it ideal for teams running multiple models, trying various hyperparameter configurations, and managing model versions across time.

Key benefits:

• Centralized hub for tracking ML experiments and managing metadata

• Enhances reproducibility, collaboration, and experiment governance

• Integrates seamlessly with popular ML tools and custom workflows

What are the main features of Neptune?

Comprehensive experiment tracking

Neptune allows teams to log and monitor all aspects of an ML experiment:

• Track hyperparameters, metrics, loss curves, evaluation scores, and artifacts

• Supports real-time logging and offline synchronization

• Organize experiments using tags, namespaces, and custom metadata

• Easily filter and search large volumes of experiment runs

Model registry and version control

Neptune includes a built-in model registry to manage model iterations:

• Register and version trained models and associated metadata

• Link models to specific experiments, datasets, and configurations

• Compare versions across projects, teams, and environments

• Support for tracking production-ready vs. experimental models

Collaboration tools and shared dashboards

Designed for collaborative ML workflows:

• Create shared projects and dashboards for team-wide visibility

• Annotate runs, flag key experiments, and assign responsibilities

• Maintain centralized documentation and experiment notes

• Promote alignment across data science, engineering, and research

Flexible integration with ML stacks

Neptune is framework-agnostic and fits into most ML pipelines:

• Compatible with TensorFlow, PyTorch, Scikit-learn, LightGBM, XGBoost, etc.

• Works with notebooks, scripts, and CI/CD tools

• Python and REST APIs for custom integrations

• Export logs and metadata to external platforms for reporting or visualization

Scalable for enterprise teams

Built for production-scale experimentation:

• Handles large-scale logging and multi-user access

• Offers role-based access control, project-level permissions, and audit trails

• Supports cloud and on-prem deployment

• Designed to meet compliance and governance requirements
