Quant-UX combines three jobs that normally live in separate products: sketching an interface, letting people try it, and analysing what they did. You lay out screens in a browser-based designer, link them into a clickable flow, then share a test link and watch how participants actually move through it.

Learning from usage

Instead of relying on opinions, it records clicks, scroll behaviour, task completion and drop-off points. Heatmaps, session replays and funnel views show where people hesitated or went the wrong way, so design decisions can be backed by numbers. Surveys and simple task definitions can be attached to a test to capture the reasoning behind the behaviour.

• Drag-and-drop screen design with reusable components
• Interactive prototypes with transitions and form logic
• Heatmaps, click maps and session replay
• Task analysis and conversion funnels

It is built with Vue and can be self-hosted, which is helpful for teams that handle sensitive prototypes or participant data.
