Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Namespace

  • Developer plan is pay-as-you-go only; minimum usage unclear
  • Team plan $100/mo is competitive but usage limits may be tight
  • Devbox pricing separate at $0.004/minute could add up quickly
  • Enterprise plan requires custom sales conversation

ProtoPie

  • The free plan allows 2 prototypes, 8 scenes per prototype and 50MB of cloud storage
  • Free prototypes carry a watermark and shareable links require the Basic plan
  • Saving prototypes locally requires the Pro plan
  • Team libraries and handoff recordings require the Pro plan
  • Basic caps storage at 500MB and prototypes at 20
  • Single sign on, private servers, custom fonts and custom hardware integrations are Enterprise only
  • Enterprise requires a minimum of 3 seats and is priced by quote
  • Connect Core is a paid add on at $20 per user per month
