Where each one falls short

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

Arize AI

The free plan caps trace spans at 25,000 per month with only 15 days of retention.

Pricing beyond the $50/month Pro plan requires a custom quote, making cost planning less transparent at scale.
Advanced compliance features like HIPAA are only available on Enterprise.

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
