UXtweak is a multifunctional UX research platform: card sorting, tree testing, first-click and preference tests, prototype/website/mobile testing, plus behavior analytics (heatmaps, session recording), with access to a 130+ country participant panel.
Free plan and free trial available (depending on research method). Business: ~€92/month (or reported $49-99/month range). Custom Enterprise pricing for unlimited users and advanced features.
Research teams wanting one platform covering both IA studies (card sorting, tree testing) and broader usability/behavioral testing, rather than separate specialized tools.
Pricing is per research method rather than a flat subscription: confirm which specific test types (card sorting vs. session recording vs. prototype testing) a quoted plan actually includes before comparing cost against a single-purpose competitor.
