Plain-Python workflow authoring
Write workflows in plain Python and develop them locally before running the same code in production.
Metaflow
RevendiquerMetaflow is an open-source framework for building and managing ML, AI, and data science workflows in plain Python, from local testing to production deployment.
What Metaflow is
Metaflow is an open-source framework for building and managing real-world ML, AI, and data science projects. It is designed for practitioners who want to develop workflows in plain Python, test them locally, and then move the same code into production without rewriting the project.
The platform combines workflow orchestration, experiment tracking, cloud execution, and data access into a single approach. It is built for ML/AI engineers and data scientists who need to work with notebooks, local debugging, scalable compute, and production deployment in the same system.
Features
Automatic versioning and tracking
Store and track variables automatically so experiment results and debugging context are preserved as the flow runs.
Production deployment and event integration
Deploy workflows with a single command and connect them to other systems through events.
Elastic cloud compute
Scale execution on cloud infrastructure with GPUs, multiple cores, and multiple instances in parallel.
Data-aware workflow handling
Access data from data warehouses while keeping data versioned as it moves across steps.
Multi-cloud and Kubernetes support
Run the stack on AWS, Azure, Google Cloud, or Kubernetes, including on-premises Kubernetes deployments.
Use Cases
End-to-end model development
Build Python-based ML workflows that need local iteration first and production deployment later, without maintaining separate code paths.
Experiment tracking and debugging
Run experiments, compare results, and debug flows using automatically tracked variables and stored outputs.
Large-scale compute workloads
Scale training or other compute-heavy steps using cloud resources such as GPUs, multiple cores, and parallel instances.
Production orchestration and automation
Deploy workflows that need to react to changing data or external events through event-driven integrations.
Infrastructure-aware team adoption
Adopt a workflow framework that can fit into existing cloud or Kubernetes infrastructure and data governance requirements.

FAQ
What is Metaflow for?
Metaflow is designed for building and managing ML, AI, and data science projects in plain Python. The source describes it as a framework for real-world ML, AI, and data science, aimed at ML/AI engineers and data scientists.
Can I develop locally before deploying?
Yes. The homepage says you can get started on a laptop, develop and debug locally, and then deploy the same flows to production without code changes.
How does Metaflow fit into existing infrastructure?
The homepage says Metaflow can integrate with other systems through events and can access data from data warehouses. It also supports deployment to cloud infrastructure or on-premises Kubernetes.
Is pricing published on the site?
The pricing page at `/pricing` returned a 404 in the collected sources, so there is no pricing information available from the provided evidence.
