Tech website design has to explain something invisible. 152 sites here from hardware, software and infrastructure companies, recorded end to end as full-page video — which is how you see whether a product demo actually demonstrates anything. Watch the opening line: the weakest name a category, the strongest name a problem. Then watch what carries the explanation — a diagram, a looping product capture, or three paragraphs someone hoped would do it. The recurring failure is a page that is confident and beautiful and leaves you unable to say what the company sells. Sorted newest first.
