Mockflow

Mockflow is a collaborative UI planning and design platform that combines wireframing, user interface sketching, and visual collaboration in a single workspace. It provides an online whiteboard tailored for product teams to brainstorm, map, and validate interface ideas before development. Users can create low- to medium-fidelity wireframes using an extensive library of UI components for web, mobile, and desktop applications, as well as custom elements and templates.

The tool supports real-time collaboration, allowing multiple team members to edit, comment, and provide feedback simultaneously. Integrated annotation, version history, and commenting features help track design decisions and changes over time. Mockflow also enables the creation of interactive user flows and sitemap diagrams, helping teams visualize navigation, information architecture, and end-to-end user journeys.
