The short version

  • Only Retool has a free tier, so it costs nothing to try first.
  • Each has a real cost: Optimizely no pricing is published and no minimum is stated; Retool builders and internal users are billed as separate seat types, so the true cost depends on the mix rather than the headcount
  • They diverge on capability: Optimizely covers A/B testing, Retool covers Drag-and-drop builder.
  • Prices and features above were last checked on 30 August 2026.
