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.
Warning
Consent tooling does not guarantee legal compliance by itself. Your policies, disclosures, vendor list, regional behavior, and record-keeping still need to match your legal requirements.
