What each one reported

10Web: 10Web needs no company data — email, first name, last name, password were enough. The AI first presents a plan that has to be approved before generation starts; that approval step blocked the build until it was clicked. The result is a WordPress site on a 10web.cloud subdomain, and the generated content itself is solid: all three services with prices, a contact section, studio text. But the front page was never assigned, so the shared URL is empty, and the contact form is inert. Both are setup failures a normal user would hit too. Scored against all eight landing criteria after the spec was aligned to the same eight-point scale as the booking tests.

Durable: Fastest run of all: five minutes from signup to a generated page, no company data needed, no credit card. The content is good and includes all three prices. Two serious problems: the page cannot be published without a paid plan, so the URL stays in preview mode; and Durable invented four customer testimonials with names and job titles ('Elena M., Valletta resident', 'James T., Architect, Sliema' and so on) that nobody ever wrote. A new site owner who publishes that would be publishing fabricated reviews. The contact details are also placeholders (+1 234 567 8900, [email protected]). Scored against all eight landing criteria after the spec was aligned to the same eight-point scale as the booking tests.
