Quant-UX is an open-source tool for UX design and research. It is positioned not merely as a prototyping tool, but as a complete loop covering “building interactive prototypes — sharing tests — collecting user behavior — analyzing results.” The page shows version 5.0.24, with its core value proposition being rapid validation of design ideas and data-driven insights to support decision-making.
On the prototyping side, it offers a visual canvas, interactive components, animations, logic flows, form validation, data binding, design tokens, components, and master screens. It also includes an AI Assistant for generating prototype snippets or reducing repetitive work. The size of the asset library is not clearly stated, but it mentions functional components such as WireFrame, Survey, iOS, and Android. In terms of compatibility, it supports importing .webp, .jpg, and .psd images, and also mentions downloading/importing from Figma.
Quant-UX’s strength lies in the research workflow: users can participate in tests via a link or QR code without installing an app. The tool automatically records screens and supports user tasks, A/B testing, surveys, 5-second tests, and more. Its analytics capabilities include heatmaps, user journeys, drop-off, task success rate, time spent, number of interactions, and KPI dashboards. The page also explicitly lists Real-Time Collaboration, making it suitable for teams to design and test together.
The page emphasizes that Quant-UX is Free and OpenSource, and states that the free offering includes unlimited prototypes, unlimited user tests, a prototype canvas, real-time collaboration, analytics, and surveys. No paid plans were found. It is worth noting that the terms of service state that copyright in the website materials is retained by Quant-UX or its licensors; user-submitted content must be legal and non-infringing, and users grant Quant-UX a worldwide, irrevocable, non-exclusive, royalty-free license to use it for internal analysis and product improvement.
Its advantages are that it is free and open source, with a complete set of testing and analytics features. It is especially suitable for UX research, classroom teaching, early-stage product validation, and comparing A/B design options. Its limitations are that the page does not disclose details on SLA, customer support, enterprise support, Chinese localization, full export capabilities, or data compliance. The AI features are also not explained in much depth. If a team mainly focuses on high-fidelity visual design, it may still need to be used alongside tools such as Figma.
The crawled text does not provide information about access from mainland China, ICP filing, domestic nodes, or payment options, so this remains unknown. Fortunately, its free model does not involve the usual payment barrier. If access or team collaboration proves unstable, alternatives or complementary tools such as Figma, Axure RP, ProtoPie, Maze, and Useberry may be worth considering.
