The short version

  • Each has a real cost: KNIME the free Analytics Platform runs locally only, so anything shared or scheduled requires a paid Hub; Neptune.ai free tier limited to 100 hours per month, exhausted quickly with serious ML work
  • They diverge on capability: KNIME covers Visual workflows, Neptune.ai covers Experiment tracking.
  • Prices and features above were last checked on 30 August 2026.
