What is ZenML?
ZenML is an open-source framework for orchestrating ML and LLM pipelines (including agent tasks), offering versioned artifacts, caching, and infrastructure abstracted as stacks. You write pipelines and agents in Python and run them on the orchestrators and clouds you already use without rewriting. Kitaru is an evaluation tool that takes sessions an agent actually ran, replays them with your changes, and shows improvements, regressions, and cost. Both are Apache 2.0 open source, and a paid Pro (managed control plane) is offered as SaaS or on your own infrastructure.
- Run Python pipelines and agents on your existing orchestrators and clouds
- Automatic code containerization and run tracking (metrics, logs, metadata)
- Artifact management and a basic model registry
- Kitaru: evaluation and regression testing based on replaying production sessions
- Import traces exported from Langfuse, LangSmith, and others
- Integrates with tools such as MLflow, LangGraph, SageMaker, and Vertex
- Pro: Model and Artifact Control Plane, snapshots, remote IDE
Who uses ZenML and for what
- Enterprise ML and AI engineers run traditional ML, LLM workflows, and agents
- Test agent changes against real past sessions before deployment
