Overview

Quant-UX is an open source prototyping and user research tool. A visual editor is used to draw app screens, connect them and add animations, logic flows and form validation, with design tokens, components and master screens for reuse. Prototypes are shared by link or QR code, and each test is recorded and turned into heatmaps, success rates, task timings and drop-off analysis.

Best for: UX researchers and design teams who want to prototype and run usability tests in one tool
Pricing: The pricing page shows a single free plan and states the product is open source; no prices or paid plans are published.
