Tooling that data, AI and ML developers love

If you know how to write Python in Jupyter notebooks, you know how to write flows using open-source Metaflow.

No need to learn complex abstractions, new paradigms, spend time with infrastructure, or navigate between six separate tools.

Take projects from prototype to production with one API

All the tools you need to develop, debug, and test locally, compute at scale, and deploy production-grade workflows and experiments behind one cohesive API.

Metaflow takes care of the foundational needs of every data-intensive project, while allowing you to use your favorite libraries and tools for your models and business logic.

Join leading ML organizations

Metaflow was created at Netflix to handle their large-scale ML and AI needs. Since its open-sourcing in 2019, it has been adopted by thousands of leading organizations.

Today, Metaflow powers tens of thousands of classic ML use cases, data pipelines, computer vision applications, and modern generative AI.

Outerbounds was like Metaflow, but with a ‘plus plus’—it made everything easier.

I've been extremely impressed by the Metaflow team. They have built something that's loved by everyone, so much so that they have Metaflow sad hours to encourage people say what can be improved. In my conversations with our users, I've often heard that Metaflow is one of the best software Netflix has ever built.

What happened to Kubeflow? So many companies are migrating away from it because it's a pain to configure and maintain. I find it hard to recommend Kubeflow anymore. Right now, Metaflow seems to be a much nicer option.

In six weeks, a team that hadn’t used Metaflow before was able to build an ML-based model, A/B test its performance, which handily beat the old simple approach, and roll it out to production.

Metaflow records the result of every step to S3. IMO the ability of metaflow to expose individual components of a complicated process is a big deal. Like, a really big deal.

A space I'm excited about: 'open source on top of public cloud tech.' Instead of using open source libraries (which you have to run & scale, e.g. RabbitMQ), it uses infinitely-scalable off-the-shelf cloud services (e.g. SQS). Metaflow is a good example. https://docs.metaflow.org/metaflow-on-aws/metaflow-on-aws

One of the things I liked about Metaflow from Netflix is their clear documentation on "Dealing with Failures": it's important to raise awareness about "retry" logic, transient/permanent failures, idempotent operations, etc.

Maybe we'll be talking about this as the "Airflow for Data Science" in a few years. Not replacing Airflow, but in the sense that it's the default standard for orchestrating data science projects like Airflow does for data engineering pipelines.

"As an informal estimate, our #datascience team believes they were able to test twice as many models in Q1 2021 as they did in all of 2020, with simple experiments that would have taken a week now taking half a day."

The MLOps piece of tech I'm most excited about is @MetaflowOSS. Just from reading the docs I'm amazed at how a large, enterprise company like Netflix seems to have really, really grasped the developer experience in the way I'd only expect 'smaller' projects to do.
