Instead of ProtoPie

ProtoPie alternatives

ProtoPie is built for high-fidelity prototypes of interactive digital experiences. Its logic, variables and formulas support dynamic behavior, while multi-touch gestures, text input, media, voice, camera access and device sensors let prototypes respond to more than taps. It imports designs from Figma, Sketch and Adobe XD, and can synchronize interactions across phones, tablets, TVs and wearables. Studio, Player, Cloud and Connect cover desktop creation, mobile preview, sharing and connected experiences.

An alternative may suit you better if you need a different workflow, output or price. ProtoPie starts at $25 per month billed yearly for Basic; its free plan limits cloud prototypes, scenes, storage and sharing, and excludes local saving and Handoff. Prototypes export only as .pie files, not PDF, JPEG or HTML code. Compare each option's purpose, collaboration, device support and exports with your priorities: some focus on web and mobile interactions, while others center on planning, wireframing, ads or visual brainstorming. Choose based on the work you need to produce, not just the ability to prototype.
