Our verdict: MLflow
Best for teams wanting a free experiment tracking tool without vendor lock-in, to install on your own infrastructure. Not for you if you are looking for a ready-to-use managed service with simple billing: outside of Databricks, there is no official MLflow cloud offering with published pricing.
Our verdict: Weights & Biases
Best for research and data science teams wanting to visually compare dozens of experiments and collaborate without reinventing a dashboard. Not for you if you are tracing high volumes of LLM calls in production without monitoring costs: Weave ingestion beyond the Pro plan is billed per megabyte and can quickly exceed budget.
