Elevate Your ML Workflows with ZenML

Compare ZenML and Prefect, two powerful workflow orchestration tools, and discover how ZenML's ML-centric features and seamless integration with the MLOps ecosystem can revolutionize your machine learning pipelines. While Prefect offers a flexible and user-friendly platform for building and managing data workflows, ZenML takes it a step further by providing a specialized solution tailored for ML pipelines. Explore ZenML's intuitive pipeline definition, built-in experiment tracking, and extensive integrations with ML frameworks and tools, empowering you to streamline your end-to-end ML workflows and accelerate your journey to production-ready models.

ZenML
vs
Prefect

Start locally without complicated setup hassle

  • ZenML is available as a simple pip package that lets you run and track pipelines locally.
  • ZenML integrates with your orchestration layer of choice, avoiding having to learn different paradigms for dev, staging, and prod.
  • ZenML integrates with your orchestration layer of choice or can be extended with your own orchestration service.

Abstract away infrastructure complexity

  • Most orchestrators assume some form of infrastructure knowledge to use them maximally — ZenML abstracts that complexity away.
  • ZenML separates infrastructure setup like Docker building from the application logic, and automates the tedious parts.
  • ZenML focuses on the handovers between MLOps Engineers, ML Engineers, and Data Scientists.

Switch between orchestrators depending on your context

  • You can switch between different orchestration services with a single click — from dev to staging to production.
  • The more engineering-minded in the team still retain control over their productionalization because the framework is extensible.
  • ZenML handles the pain of packaging your code into Docker to be deployed to your orchestration service of choice.
