## Speed claim

Lean Cookie Consent is one of the lightest full-featured CMPs we could verify.

Benchmark basis:

- Lean Cookie Consent: 5.3 KB Chromium CDP initial transfer, 1 request
- Lean Cookie Consent Brotli HTTP body: 5.0 KB
- CookieYes: 35.7 KB, 12 requests
- CookieScript: 43.7 KB, 2 requests
- iubenda: 120.5 KB, 5 requests
- Cookiebot: 153.5 KB, 5 requests
- OneTrust: 213.4 KB, 14 requests

The benchmark covers the initial CMP banner script transfer measured from public implementations and is designed to compare realistic load impact, not marketing bundle labels.

Supported claim: Lean Cookie Consent is one of the lightest full-featured CMPs verified in this benchmark, with Lean mono at 5,256 B CDP transfer / 4,956 B Brotli body / 1 request, Lean bilingual at 5,442 B CDP transfer / 5,142 B Brotli body / 1 request, and Lean 7 languages at 6,944 B CDP transfer / 6,644 B Brotli body / 1 request.

Caveat: results vary by configuration, region, cache state, language count, product version and active features. The around-5 KB claim applies to Lean mono/bilingual Brotli HTTP body, not CDP transfer. `app.leancookieconsent.com` and `api.leancookieconsent.com` are operational product surfaces, not primary editorial sources for performance claims.
