What it does
ProtoPie builds detailed interaction prototypes for mobile, web and device interfaces. It combines design-tool imports with logic, variables, formulas and device inputs. Its free plan saves two prototypes in the cloud, with eight scenes per prototype; sharing and larger projects require paid tiers.
A prototype in ProtoPie can react to entered text, a device sensor or a message from another device. Logic, variables and formulas let you represent behaviours such as email validation instead of only linking fixed screens. Imports from Figma, Sketch and Adobe XD bring existing artwork into that interaction workflow.
What each plan allows
| Plan | Prototype and storage limits | Important distinction |
|---|---|---|
| Free | 2 cloud prototypes, 8 scenes each, 50 MB | Personal exploration |
| Basic | 20 cloud prototypes, 10 scenes each, 500 MB | Shareable links and no watermark |
| Pro | Unlimited prototypes, 5 GB per team | Local saving, team libraries and unlimited handoff recordings |
| Enterprise | Custom terms | Custom hardware integrations and administration |
Use Start for Free to create a ProtoPie account and download Studio. Build the interaction, then preview it in its intended device context. Hardware connection features can require the Connect Core add-on. The free plan's two prototypes are a lasting allowance, not a temporary full-product trial.
