  • No event cap, data point limit or user limit is published for either paid plan
  • The self hosted Enterprise edition is custom priced and billed annually
  • Adaptivity and intelligence features are separately priced add ons on the cheaper plan

Vitest

  • Assumes Vite: projects on webpack or other bundlers lose the main advantage
