What is MLflow?

MLflow is the most widely adopted open-source platform for managing the ML lifecycle, including experiment tracking, model registry, deployment, and now LLM tracing. It's vendor-neutral, runs anywhere, and integrates with every major ML framework.

Our Review

MLflow is the safe, vendor-neutral choice for ML lifecycle management. Its broad framework support and Apache 2.0 license make it a mainstay in enterprise data science teams. The new LLM tracing features close the gap with LangSmith for teams that want a single platform for both traditional ML and LLM workflows.
