In their own words
Overflow
Overflow lets users create, present, share, and get feedback on interactive user flow diagrams. It syncs designs from Figma, Sketch, Adobe XD, and Adobe Photoshop. Diagrams can include customizable connectors, styles, device skins, hotspots, shapes, text, and multiple boards. Users can present playable flows, self-guided Stories, and rapid prototypes. Cloud publications can be shared by link, embedded, protected with a passphrase, exported as PDF or PNG, or printed. Collaboration includes personal and team folders, editor invitations, comments, mentions, and notifications, with integrations for Confluence, Jira, and Trello. Overflow is available on macOS, Windows, and the web. Its 14-day trial requires no credit card and gives desktop-app and Cloud-sharing access without limitations. After the trial, that access ends; data remains hosted for 60 days and is then deleted if no subscription is activated. Pro costs €19.95 per user/month, billed monthly, and includes 1GB cloud storage per user, Cloud sharing, folders, and comments.
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.
