  • Pro-to-Business pricing jump ($49 to $399/month) is steep for mid-sized teams that outgrow the hobby limits
  • LLM-as-a-judge and automated evaluators still require careful calibration to produce reliable signals on domain-specific tasks
  • Deep integrations with niche agent frameworks or custom orchestration may require manual SDK instrumentation
