In their own words
ProtoPie
ProtoPie is a high-fidelity platform for creating and testing interactive digital prototypes. Studio for macOS and Windows supports logic, variables, formulas, 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 product 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 includes two prototypes saved in Cloud, up to eight scenes per prototype, and 50MB of Cloud storage. ProtoPie lists Basic at $25 a month billed yearly, and Pro at $47 a month billed yearly. Free-plan limitations include no local file saving, share links, Handoff, or Team Libraries. Prototypes export only as.pie files, not PDF, JPEG, or HTML code.
Zeplin Flows
Zeplin Flows helps teams map user journeys and make design intent clearer across screens. Diagrams use labels, shapes, and connectors that reposition when screens are added or removed. Teams can group screens and flows into Flow Groups and Boards, then share them through quick links. Shapes can represent actions, decisions, and branches, helping product, QA, and Support teams identify gaps and add use cases. Flows are included across plans, while Flow Boards are available on Advanced and Enterprise. The Free plan is free and includes one project, 100 screens, unlimited members, and no Flow Boards. Advanced costs $12 a month, billed annually. Zeplin offers Mac and Windows desktop apps and a web app that works on Windows, macOS, and Linux; the web app does not support uploading designs. Listed integrations include Figma, Sketch, Jira, Storybook, VS Code, Azure DevOps, Slack, Microsoft Teams, an API, and webhooks. Developer inspect view, design tokens, asset handoff, code snippets, and version history are listed.
