Quant-UX review
A broad open-source workspace for prototyping, testing, and product insight.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Quant-UX is an open-source UX design, prototyping, usability testing, and analytics tool for designers, researchers, and product teams. Its visual editor supports interactive screens, widgets, transitions, animations, logic flows, form validation, and data binding. Teams can share prototypes through links, run user tests, collect recordings and questionnaires, and review analytics such as heatmaps and task results. Web access and self-hosted deployment give teams two platform options, while the Free plan includes unlimited prototypes and unlimited user tests.
The product’s main distinction is its breadth across the design research cycle. Real-time collaboration supports shared work, while questionnaires, surveys, screen recordings, analytics, heatmaps, and task results connect prototype creation with user feedback. Design tokens, reusable components, and master screens support structured design work. Figma project import can help teams bring existing projects into Quant-UX, and integrations with Figma and REST or web services extend its workflow. Web services, data binding, and scripts also support more interactive prototypes than simple screen-to-screen demonstrations.
Quant-UX suits teams that want open-source control, self-hosting, and a single environment for prototyping and testing. It is particularly relevant when research features such as shared links, recordings, questionnaires, analytics, and heatmaps matter alongside interface design. Teams primarily seeking a dedicated developer handoff workflow should compare alternatives carefully, because those capabilities are not detailed here. Quant-UX is also a better fit for organizations prepared to manage a broad toolset than for teams looking for a narrowly focused prototyping canvas.
Quant-UX pros and cons
- Where it wins

- Combines collaboration, testing, surveys, analytics, and heatmaps
- Supports Figma import, tokens, components, and self-hosting
- Where it doesn't
- Developer handoff capabilities are not detailed
- The platform may be broader than teams needing only prototyping
- Self-hosting can add deployment and maintenance responsibility
