      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.
