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.
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.
