Best for ML teams running many large or long-running training jobs who need fast, high-volume metadata logging. Teams wanting free, self-hostable experiment tracking without committing to a vendor's hosted SaaS. Teams wanting a polished, collaborative hosted experiment tracker with an enterprise self-hosting option. Teams wanting one vendor for both classic experiment tracking and LLM/agent observability. Teams wanting a single open-source platform that combines experiment tracking with pipeline orchestration and deployment.
