The short version

  • Each has a real cost: Airtable hitting a plan limit blocks adding records or attachments entirely until you upgrade, rather than degrading gracefully; Neptune.ai free tier limited to 100 hours per month, exhausted quickly with serious ML work
  • They diverge on capability: Airtable covers Spreadsheet-database hybrid, Neptune.ai covers Experiment tracking.
  • Prices and features above were last checked on 30 August 2026.
