Experiment without chaos: Empower data scientists with human-friendly tools that work with infrastructure approved by engineers.
Diverse projects and people need an open source framework
Data, ML, and AI projects come in different shapes and sizes: transformations, forecasting, deep learning. All benefit from a flexible open-source framework.
Deploy more experiments to production, faster
Result: More data, ML and AI applications deployed to enterprise-grade infrastructure by happier people, producing sustainable business value.






An open-source, human-centric framework for developing data, ML, and AI apps
With Metaflow data scientists can design and develop projects independently. They can use their favorite libraries and deploy on infrastructure approved by their engineering team.
A reliable platform for executing data, ML, and AI apps
Outerbounds Platform provides production-grade infrastructure for diverse data, ML, and AI apps, deployed on your cloud account, integrated to your systems and policies. Fully managed by the creators of Metaflow.


Secure by Design
Security is in our DNA, not at the perimeter. The platform uses industry-standard tools and best practices to comply with your existing security policies and compliance requirements.
Efficient Compute
Data-intensive apps are compute-intensive apps. The platform provides a scalable, cost-efficient compute for diverse workloads from data transformations to GPU-based deep learning.
Robust Integrations
ML/AI and data apps can't produce value on an island. The platform integrates seamlessly with your surrounding infrastructure, from data warehouses to microservices.
Managed High Availability
It takes a village to operate modern ML/AI and data infrastructure. Based on hard-earned lessons from Netflix and other top organizations, we provide a headache-free platform for your teams.
Backed by a vibrant open-source community
Since 2019, Metaflow has been adopted by hundreds of leading organizations across industries and used by thousands of engineers and data scientists. Join our vibrant community to learn more!
