# zenml — ZenML: MLOps for Reliable AI: from Classical AI to Agents.

License: permissive · Maintenance: active · Downloads: 198.6K/mo

## What it is and what it does

ZenML is an MLOps orchestration framework designed for teams running traditional ML, LLM workflows, or agentic systems in production. It abstracts infrastructure complexity by letting you write pipelines in Python, then automatically containerizes, tracks, and deploys them across any backend—local, Kubernetes, cloud providers, or custom stacks. At its core, you wrap your existing code in @step and @pipeline decorators; ZenML then handles containerization, artifact tracking, metrics logging, and integration with tools like MLflow, Weights & Biases, and cloud platforms.

The platform is built on a client-server architecture with an integrated web dashboard. You can start locally with `pip install "zenml[local]"` for development, then deploy the server separately and connect via `zenml login` for production. It supports Python 3.10 through 3.14 and depends on well-maintained libraries (pydantic, docker, opentelemetry, click, rich) for configuration, containerization, observability, and CLI interaction. The project is actively maintained, with recent releases and thousands of companies using it.

Use it for:

- Orchestrate end-to-end ML pipelines with feature engineering, model training, and batch inference across distributed infrastructure.
- Deploy and monitor LLM applications and RAG systems with built-in evaluation loops and production observability.
- Build and manage agentic workflows that integrate with existing Python tools and frameworks with automatic run tracking.
- Unify classical ML model deployment and AI agent management in a single framework without rewriting existing code.
- Iterate rapidly on experiments in development with automatic artifact versioning, then promote to production without changes.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

ZenML is an MLOps orchestration platform that lets you write pipelines and deploy them across any infrastructure backend, automatically handling containerization, run tracking, and integration with existing ML tools.

Yes. ZenML is actively maintained, has low install friction, uses a permissive Apache-2.0 license, and has no known security vulnerabilities. It solves a real problem—orchestrating ML and AI workflows across infrastructure—without requiring you to rewrite existing code. Suitable for teams moving from ad-hoc scripts to production MLOps, though the 17 runtime dependencies and learning curve around stacks warrant evaluation in your specific environment.

## Install

pip install zenml
uv add zenml
poetry add zenml

## Installing zenml

Before you install: Low friction install with a pure Python wheel. Active maintenance with a recent release (7 days ago) and 5557 GitHub stars. Depends on 17 runtime packages including docker, pydantic, and opentelemetry, which are well-established libraries.

License in practice: Apache-2.0 permissive license allows commercial use, modification, and distribution with minimal restrictions—suitable for most production and proprietary settings.

Quickstart:

pip install zenml
zenml init
zenml login

from zenml import pipeline, step

@step
def my_step():
    return "result"

@pipeline
def my_pipeline():
    my_step()

Requires Python 3.10 or later (up to 3.14). The [server] extra installs additional dependencies for running a local ZenML server; the base install provides a client-only mode.

Verify before relying:

- Whether the 17 runtime dependencies introduce significant transitive dependency bloat in production environments.
- Performance characteristics and scalability limits when orchestrating large numbers of concurrent pipeline runs.
- Specific cloud provider support coverage beyond the documented integrations (MLflow, Langfuse, Sagemaker, GCP Vertex).
