c15t vs Iubenda

Iubenda offers cookie banners, Consent Management Platform workflows, tracker scanning, cookie blocking, Google Consent Mode support, and a Consent Database for recording consent.

c15t is the better starting point when consent needs to live in your app, backend, and framework code. Iubenda is useful when you want a hosted compliance suite with policy generation, scanning, dashboards, and consent database workflows. CookieBench also lists c15t's Next.js and React examples above Iubenda on score, banner visibility, and network impact.
