Where each one falls short

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

Helicone

  • The free Hobby plan is capped at 10,000 requests per month, which teams with production traffic can exceed quickly.
  • Advanced compliance features like SOC 2 and HIPAA are only available starting at the $799/month Team plan.
  • Usage beyond the free tier is billed on top of the base subscription, adding cost unpredictability at scale.
  • On-premises deployment is restricted to the custom Enterprise tier.

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
