# Designesy — /score/v0 Canonical page: https://www.designesy.org/score/v0 --- ## Score your v0 site 42 checks. One grade. Built on v0? See how close you are to a published design contract. v0 generates production React. The Designesy engine runs the same 42 checks against any v0-built URL and returns an honest grade — pass, fail, warn, or skip — against tokens, motion, typography, accessibility, and identity rules. The example below is prefilled with v0.dev — score it live to see where it stands today. Score your **v0** site below — the engine runs the same 42 checks against your URL as it does against any other. Legitimacy Audit Engine Enter any public website URL above — no https:// needed. We fetch its CSS, extract design tokens, and evaluate 42 verification checks against the Designesy contract v0.4.0. Real-time. No login required. ## What you get A letter grade, a per-check breakdown (pass, fail, warn, skip), the tokens extracted from your site’s `:root`, and a copyable receipt citing the contract version. No login. No backend. No data kept. The score is the artifact. The contract the engine runs against is public at [/contracts/design-system](/contracts/design-system). The category it defines is explained at [/learn/what-is-design-verification](/learn/what-is-design-verification).
