What Quant-UX is

Quant-UX is a research, usability, and prototyping tool for testing designs and gathering data-driven insights. Its visual designer lets users create screens, add functional components, and connect them with interactions. Design systems can include reusable components, design tokens, and master screens. Testers can open a shared prototype link without an app, or scan a QR code to launch one on a phone. Built-in analytics include heatmaps, user journey and drop-off graphs, task KPIs, and visual comparisons for A/B tests. The Free plan includes unlimited prototypes and user tests. Quant-UX also lists real-time collaboration, variables and tokens, and prototype sharing, and it connects with Figma. It is available through the web or as a self-hosted deployment; the maker says the code is open source and can be downloaded, improved, and contributed back. The maker says its servers and databases are in the EU and that traffic is encrypted with SSL/TLS. Optional AI features send prompts and design data to a selected provider, which may process them outside the user’s country; most AI features require the user’s own provider API key.
