ProtoPie: cost, fit and limits
ProtoPie is an interactive prototyping application that builds app and device prototypes with logic, variables, formulas, voice and sensor interactions. The pages checked name no maker or headquarters country. It has a free plan, a single-seat Basic plan and a team Pro plan, and its AI drafts interaction logic.
What to know first
ProtoPie targets interaction designers who need prototypes that behave like the finished product: formulas, variables, voice input, device sensors and multi-device interactions. Pricing runs from a free plan, to Basic at $25 per month for a single seat, to Pro at $47 per editor per month. AI Credits are included on Basic. The vendor's privacy policy links returned 404, so its data handling could not be checked.

Who ProtoPie is best for
Interaction designers
Logic, variables and formulas support dynamic behavior, for example validating an email address, which static screen tools cannot show to testers.
Hardware and IoT teams
Connect Core adds hardware integrations, and the pages mention Arduino and native hardware on a free trial. A free trial of that hardware integration is mentioned on the pages checked.
Teams handing prototypes to developers
Handoff recordings are included from Basic, with unlimited handoff recordings on Pro, so developers can replay intended behavior. Developers replay behavior instead of guessing.

What ProtoPie does
- Dynamic interactions
- Interactions use logic, variables and formulas, so a prototype can validate input or branch the way the product will. Authors can set rules, store values and compute results, so a prototype checks input the way production code will.
- Voice and sensors
- Prototypes can use voice interactions and native device sensors, which tests flows that depend on the phone itself. Voice and sensor input is part of the prototype, which suits mobile and in-car testing where touch is not the only input.
- Cross-device prototypes
- Multi-device and cross-device interactions link several screens or devices into one test, such as a phone controlling a display. A prototype can span devices, so a phone can drive another screen in a test session.
- AI drafting
- The page names AI that generates interactions and a Logic-grade AI prototyping flow in which AI drafts a logical blueprint the user refines. Basic includes AI Credits.
- Handoff recordings
- Handoff recordings let developers replay prototype behavior, with 1 on Basic and unlimited on Pro. Basic includes 1 recording, while Pro includes unlimited ones, and the recordings carry the intended interactions to engineering without a long written specification.
How ProtoPie handles your data
The ProtoPie privacy policy URLs returned 404 when checked, so training use of customer content, retention and hosting region could not be confirmed and the vendor's policy was not checked for them. The pricing page names ISO 27001 and 27701 compliance, and Enterprise lists ISO-compliant security, MFA, SSO and SCIM. The pages opened also do not state the legal maker or headquarters country. Cloud storage is capped at 50 MB on Free, 500 MB on Basic and 5 GB per team on Pro, and Pro allows prototypes to be saved locally.
Where ProtoPie falls short in practice
- . The $25 Basic plan covers one seat only, so a team moves to Pro at $47 per editor, almost double the per-seat price. Free offers 2 cloud prototypes.
- . Free allows 2 cloud prototypes with 8 scenes each and 50 MB of storage, which is enough to try the editor but not a real project.
- . Connect Core is an add-on on Basic and Pro, and User Testing is available only on annual billing on Pro. Pro users on monthly billing cannot run User Testing, which the page limits to annual plans.

Alternatives to ProtoPie
ProtoPie: common questions
Does ProtoPie include AI?
Yes. The pages name AI that generates interactions and a logic-grade AI prototyping flow where AI drafts a logical blueprint for the user to refine. AI Credits are included on Basic, and Pro lists MCP Core. Credit amounts were not stated on the pages checked.
What is the difference between ProtoPie Basic and Pro?
Basic is $25 per month, single seat, with 20 cloud prototypes and 10 scenes each. Pro is $47 per editor per month with unlimited prototypes and handoff recordings, 5 GB of team storage, local saving, team libraries and MCP Core.
Can I save ProtoPie prototypes locally?
Local prototype saving is listed on the Pro plan. Free and Basic save prototypes to the cloud, with 2 and 20 prototypes allowed. If your policy forbids cloud storage of unreleased designs, Pro or Enterprise is the starting point. Pro also lists team libraries.
Where is ProtoPie's privacy policy?
The privacy policy URLs tried returned 404, so its content was not read. The pricing page names ISO 27001 and 27701 compliance. Request the current policy and data processing terms from the vendor before uploading confidential prototypes. Enterprise lists ISO-compliant security.
Does ProtoPie work with hardware?
Connect Core is a hardware and integration add-on on Basic and Pro, and Enterprise lists custom hardware integrations. The pages mention Arduino and native hardware on a free trial. Supported device lists were not itemized. Pro lists MCP Core, and Enterprise lists MCP Enterprise.
