Summary

Overflow is a tool for creating and presenting interactive user flow diagrams, then sharing them for feedback. 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 make playable flows, self-guided Stories, and rapid prototypes. Cloud publications can be shared by link, embedded, protected with a passphrase, exported to PDF or PNG, or printed. Collaboration options include personal and team folders, editor invitations, comments, mentions, and notifications, with integrations for Confluence, Jira, and Trello. Overflow is available for macOS, Windows, and web browsers. The 14-day trial requires no credit card and includes 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 EUR per user/month, billed monthly, and includes 1GB cloud storage per user, Cloud sharing, folders, and comments. Enterprise pricing is available by contacting sales.
