|---|---:|---:|---:|
| Total score | 95 | 63 | +32 |
| FCP | 63ms | 98ms | 36ms faster |

c15t is the open-source consent standard built for performance-sensitive teams: it can be bundled with the app, avoids a mandatory third-party CMP script request, and remains auditable. If Usercentrics is being evaluated mainly for compliance coverage, compare it against c15t on the live CookieBench metrics before accepting the consent-script performance cost.
