What Quant-UX is
Quant-UX is a research, usability and prototyping tool for creating interactive designs and collecting data-driven insights. Its visual designer builds screens, functional components and connected interactions. Users can create design systems with reusable components, design tokens and master screens, while real-time collaboration supports shared work. Testers open prototypes through a shared link without installing an app, or scan a QR code to launch them on phones. Built-in analytics include heatmaps, user-journey graphs, drop-off graphs, task KPIs and visual A/B comparisons. Quant-UX offers unlimited prototypes and unlimited user tests on its Free plan. It connects with Figma and runs on the web or through self-hosted deployment, with cloud hosting also available. The maker describes the code as open source and invites downloads, improvements and community contributions. Quant-UX says its servers and databases are in the EU, with SSL/TLS encryption and restricted server access. Optional AI features may send prompts and design data to a selected provider outside the user’s country.
