              What buyers like

              • Unlimited free experiments for individual users — one of the most generous free tiers in MLOps, covering solo data scientists and researchers completely.
              • Automatic code and environment capture alongside metrics makes experiments truly reproducible without manual documentation effort.
              • Native LLM evaluation via Opik extends beyond traditional ML to cover the modern LLM workflow, making it a single platform for both classical ML and LLM teams.

              Common complaints

              • UI can feel dated compared to newer entrants like W&B — the experiment comparison and visualization experience is functional but not as polished.
              • Team pricing jumps significantly from free to $179/month, making it expensive for small teams who have outgrown the individual tier but do not need full enterprise.

              Pros and Cons

              • Integration of data tracking, pipeline processing, and result evaluation in one environment

              • Performance comparable to handwritten models

              • Flexibility similar to scikit-learn for prototyping and production

              • Limited information on pricing transparency

              • Relatively small user base and review count
