Where each one falls short

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

ConfigCat

  • There is no experimentation or statistical analysis engine, so teams wanting real A/B tests with significance testing must buy and integrate a separate analytics or experimentation product
  • Pricing by flag count punishes exactly the hygiene you want: the Pro tier caps at 100 flags, so teams that do not aggressively retire stale flags are pushed to the 325 dollar Smart tier for housekeeping reasons rather than growth
  • The free tier allows only 2 environments, which does not cover the common development, staging and production split, so almost any real deployment starts on a paid plan
  • It is a smaller vendor than the category incumbents, so enterprise procurement teams will find less depth in compliance attestations, contractual terms and reference architecture than LaunchDarkly offers
  • Flag evaluation relies on SDK-side caching of a CDN-delivered config, which is fast but means propagation of a change is eventually consistent rather than instant, something to understand before relying on it as an emergency kill switch

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

ConfigCat: Is the free tier usable?

For small projects yes, but at 10 flags and 2 environments it will not cover a dev, staging and production setup.

ProtoPie: Is there a free version of ProtoPie?

Yes. The free plan includes 2 prototypes, 8 scenes per prototype, and 50MB cloud storage. Perfect for trying the platform.

Source
ConfigCat: Can it run A/B tests?

It can split traffic, but there is no statistics engine. You need a separate analytics tool to decide a winner.

ProtoPie: What is included in the Pro plan?

Pro plan at $47/month includes unlimited prototypes, unlimited handoff recordings, 5GB team storage, local saving, and team libraries per editor.

Source
ConfigCat: How fast does a flag change take effect?

SDKs poll and cache, so changes propagate on the polling interval rather than instantly.

ProtoPie: What add-on products does ProtoPie offer?

Connect Core ($20/month per user), Connect Enterprise and Connect Embedded (custom pricing), and User Testing (custom pricing, annual-only for Pro plan users).
