Quant-UX

Open-source tool for creating interactive prototypes, running user tests, and analyzing results.

Webfreeglobal

An open-source, self-hostable web app for building interactive prototypes, running user tests, and analyzing results. It helps teams avoid subscription-based prototyping and the need to stitch together separate testing and analysis tools, and is aimed at designers, UX researchers, and product teams rather than as a full design-systems platform.
