The short version

  • Only ProtoPie has a free tier, so it costs nothing to try first.
  • Each has a real cost: Proto.io prototypes live in the vendor cloud and offline export is a higher-tier feature, so the ability to archive completed client work is a plan-level decision rather than a given.; ProtoPie the free plan allows 2 prototypes, 8 scenes per prototype and 50MB of cloud storage
  • They diverge on capability: Proto.io covers Event and condition system, ProtoPie covers Interactive prototyping.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

Where each one falls short

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

Proto.io

  • Prototypes live in the vendor cloud and offline export is a higher-tier feature, so the ability to archive completed client work is a plan-level decision rather than a given.
  • Design is done elsewhere and interaction is rebuilt here, so every change to the visual design has to be reapplied by hand and the two artefacts drift apart.
  • The event and condition model is layer based, so a genuinely complex flow becomes a large tree of triggers that nobody but its author can audit.
  • Editor seats are priced individually and viewer access is limited on lower plans, so opening review to a wide stakeholder group pushes you up a tier for people who never edit anything.
  • The market standardised on Figma, so hiring people who already know Proto.io is progressively harder and every new researcher is a training cost.

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

Answered from the vendors’ own pages

Proto.io: Can it replace Figma?

No. It has no design system or file-handoff role. It sits alongside Figma for the prototypes Figma cannot express.

ProtoPie: How much does ProtoPie cost?

ProtoPie offers a free plan ($0/month), Basic at $25/month, and Pro at $47/month per editor. Annual billing offers up to 26% savings. Enterprise pricing is custom for minimum 3 seats.

Source
Proto.io: What happens to prototypes if we stop paying?

They stop being accessible unless you have exported them, and offline export is restricted to higher plans, so plan archiving before you cancel.

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
Proto.io: Is it worth learning now that InVision has gone?

If your work is usability research on conditional flows, yes. If you need click-through demos of static screens, Figma already does that at no extra cost.

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
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).
