Tests
Two briefs. Every builder. Eight criteria each.
We do not review features in the abstract. Each builder gets the same written brief, the same week, and the same automated checks. Below are the briefs and every run published against them.
booking-app-v1
Booking app
A landing page, a booking form that stores submissions, a confirmation email, an admin list and a public URL. Eight binary criteria, no login, no payment.

landing-page-v1
Landing page
The same studio as a plain website: hero, three services with prices, a contact form, working navigation and a footer. For builders that ship no database.

Method, criteria and the limits of each score: methodology. Every figure links to a published run with its own screenshots.
