Top Software Testing Companies for UI/UX Design

23 software testing companies ranked by rating, review volume and listing quality.

UI and UX design are usually sold together and are not the same thing. UX is the shape of the product — what it does, in what order, and what a user is trying to achieve. UI is the surface: the controls, the visual language, the details of interaction. A product can be beautifully rendered and still ask people to do something illogical.

The most informative question for a provider here is what research they do before drawing anything, and what they do when it contradicts the brief. Teams that go straight to high-fidelity screens produce work that looks decisive and tests badly. Ask to see a project where the research changed the plan.
