Quant-UX
An open-source UI prototyping and user-research platform with task tests, recordings, A/B tests, heatmaps, surveys, and analytics.
Why use it
Before implementing full game menus, teams can observe whether testers find actions, complete flows, and where they drop out.
Where it fits
Use prototypes and playtests to find core experience problems while they are still cheap to fix.
What to check
Recordings and behavioral data require informed consent and privacy controls; full self-hosting also needs backend, database, and mail setup.
