ProtoPie

ProtoPie is a high-fidelity prototyping platform for creating and testing interactive digital experiences. Its Studio apps for macOS and Windows support prototypes built with logic, variables and formulas, alongside multi-touch gestures, text input, media playback, voice, camera access and device sensors such as gyroscopes and compasses. Plugins import designs from Figma, Sketch and Adobe XD. Prototypes can connect phones, tablets, TVs and wearables, with interactions synchronized across devices. The ecosystem includes Studio, Player for mobile devices, Cloud for sharing and Connect for connected experiences; Player is available for iOS, iPadOS, Android and HarmonyOS. The Free plan allows two prototypes saved in Cloud, up to eight scenes per prototype and 50MB of Cloud storage. It excludes local file saving, share links, Handoff and Team Libraries. Basic is listed at $25 a month billed yearly, and Pro at $47 a month billed yearly. Prototypes export only as .pie files, not PDF, JPEG or HTML code. ProtoPie lists hardware and API integrations alongside its design-tool imports.

ProtoPie supports prototypes with device interactions and cross-device synchronization, with a free tier and paid plans. Its export format is limited to .pie, and some sharing and handoff features are absent from Free.

ProtoPie suits designers and teams building interactive prototypes that use device features or connect multiple devices. The free plan may fit limited cloud prototyping, while the listed paid plans offer additional capabilities.

ProtoPie is a high-fidelity prototyping platform for teams that need device-aware, responsive demonstrations rather than static screen flows. It suits product designers, developers, and organizations modeling interactions across phones, tablets, TVs, and wearables, but its file export and Free-plan restrictions matter when sharing or handing work off.

The strongest case for ProtoPie is its unusually broad interaction model: sensors, voice, camera, formulas, and synchronized devices can all be part of one prototype. The trade-off is a proprietary workflow, with .pie as the only export format and progressively tighter limits on lower tiers.

Overview

ProtoPie combines Studio authoring for macOS and Windows, Player for mobile playback, Cloud sharing, and Connect for advanced connected experiences. Plugins import designs from Figma, Sketch, and Adobe XD, helping teams move existing UI work into an interactive prototype. The maker, ProtoPie, was founded in 2014 and is headquartered in Seoul, South Korea.

It covers interactive prototyping, design systems, variables and tokens, developer handoff, desktop apps, and prototype sharing. Its listed platforms include Android, API, iOS, macOS, self-hosted, web, and Windows, with cloud, self-hosted, desktop, and mobile deployment options. These labels describe the product footprint rather than a promise that every component runs everywhere: Studio is specified for macOS and Windows, while Player runs on iOS, iPadOS, Android, and HarmonyOS.

Key features

Logic and device input

Multi-touch gestures, conditional logic, text input, media playback, voice prototyping, and camera access let a prototype express behavior beyond tap-to-next-screen transitions. Variables and formulas support changing values and conditional responses, which is useful for testing flows that depend on state or user input.

Sensors and connected experiences

Gyroscopes, compasses, and other smart-device sensors can drive interactions. Phones, tablets, TVs, and wearables can be connected in one prototype and synchronized, making ProtoPie a strong fit for multi-device products and hardware-linked concepts.

Sharing, handoff, and controls

Cloud provides sharing, while developer handoff and design-system support address team delivery. Enterprise Cloud uses Palo Alto Web Firewall protections and annual penetration testing. ProtoPie states ISO 27001, ISO 27701, GDPR, and PCI DSS compliance; Enterprise adds SAML 2.0 and OpenID Connect SSO, including Okta, Auth0, and OneLogin. ProtoPie AI is opt-in for Basic and Pro and disabled by default for Enterprise organizations.

Export is a meaningful constraint: prototypes export only as .pie files, not PDF, JPEG, or HTML code. Teams needing broadly reusable deliverables should plan around that limitation.

Pricing

Free

Free costs nothing and allows two prototypes saved in Cloud, eight scenes per prototype, 50MB of Cloud storage, and personal libraries. Studio features exclude Team Libraries, local file saving, share links, and Handoff. It is suitable for individual exploration, but the scene, storage, and sharing caps quickly limit formal reviews.

Basic

Basic costs $25 a month, billed yearly, for one seat. It raises the allowance to 20 Cloud prototypes, 10 scenes per prototype, and 500MB of storage, and adds one handoff recording, shareable links, and no watermark. It fits a solo professional who needs presentable sharing, though one seat and a single recording restrict larger workflows.

Pro

Pro costs $47 a month, billed yearly, per editor. It removes prototype and handoff-recording limits, provides 5GB of Cloud storage per team, local saving, Team Libraries, and ProtoPie MCP beta. This is the practical tier for active design teams, provided the per-editor cost and proprietary export are acceptable.

Enterprise

Enterprise uses custom pricing, requires a minimum of three seats, and adds the organization-level SSO and security controls. It is aimed at larger deployments that need centralized identity and governance.

Platforms

Studio runs on macOS and Windows; Player supports iOS, iPadOS, Android, and HarmonyOS. Cloud, self-hosted, desktop, and mobile deployment options support different organizational environments, while API and hardware integrations extend connected prototypes.

Who it's for

Solo designers can use Free or Basic to validate interaction ideas. Small and mid-market teams gain more from Pro's unlimited prototypes, local saving, and shared libraries. Enterprise organizations with at least three seats and formal identity or security requirements have a clearer reason to choose Enterprise. ProtoPie is less suitable when stakeholders require PDF, JPEG, or HTML exports, or when a project needs generous collaboration without per-editor pricing.

Pros and cons

• Pro: Sensor, voice, camera, media, and multi-touch support can model realistic device behavior.
• Pro: Cross-device synchronization covers phones, tablets, TVs, and wearables in one experience.
• Pro: Figma, Sketch, and Adobe XD imports reduce duplicate design work.
• Con: .pie-only export limits portability into common review and delivery formats.
• Con: Free omits local saving, share links, and Handoff, with only two Cloud uploads and eight scenes per prototype.
• Con: Basic is single-seat, while Pro charges per editor.

Alternatives

Choose Justinmind instead if a free plan with one project, unlimited screens and viewers, UI design, wireframing, and interactive input forms better matches the job.

Mockplus is a better fit for a free, multi-user setup offering 10 users, 10 active projects, and unlimited designs.

Pick Pixso when unlimited viewer seats and draft files are more important than ProtoPie's device-oriented interactions.

UXPin offers a limited post-trial free plan with two prototypes and 50 AI credits.

For a Figma-centered workflow, Figma Dev Mode starts with a free Starter tier and unlimited drafts.

Marvel provides a simpler free plan with one user and one project, with Pro at $12 a month billed yearly.

Frontify is an alternative for organizations seeking a custom, monthly-active-user package.

Sketch suits macOS, iOS, and web teams wanting real-time collaboration and unlimited documents on its Standard plan at $12 a month, billed yearly.

Verdict

Choose ProtoPie when your prototype must demonstrate real device behavior, changing logic, or synchronized multi-device interaction. Pro is the most capable general team tier, while Enterprise addresses governed deployments. Look elsewhere when standard export formats, unrestricted free sharing, or a lower-cost per-editor model matter more than ProtoPie's depth of interaction.
