MockFlow

MockFlow offers a complete interface design environment that goes beyond simple wireframing: it includes tools for sitemaps, team collaboration and client feedback, all in a single platform designed for the entire UX design process.

MockFlow is a suite of online tools for UI prototyping and design. The main module is the Wireframe Tool, a visual editor with a component library — buttons, forms, navigation, mobile and web app widgets — to drag onto a canvas to build an application or website's screens. Prototypes become clickable by linking screens together, allowing navigation flow simulation. The SiteMap Tool lets you build a site's hierarchical structure visually. Collaboration features include project sharing with the team, contextual notes on screens, client feedback functionality, version history and export to PDF and images. MockFlow is valued for the completeness of the process it supports — from planning to information architecture to approved prototype — all without leaving the platform. It's less powerful than Figma for detailed visual design, but more structured for the initial UX phase and client communication.

For UX designers, product managers and development teams who want to plan, prototype and share app and website interfaces with clients in the early project phase.

MockFlow has a free plan limited to 1 project, useful for evaluating the tool. The Pro plan starts at $19 per month and includes unlimited projects, collaborators and advanced features. Team plans with more users are available for larger teams. Annual billing reduces the monthly cost.
