[Cookiebot by Usercentrics](https://www.cookiebot.com/us/developer/) is a
hosted consent tool with developer resources, automatic cookie blocking, a
manager setup flow, scanning, and cookie classification workflows.

c15t is the better starting point when consent affects the app, backend,
framework startup, or server-side behavior. Cookiebot is useful when hosted
scanning, cookie classification, and automatic blocking are the main job.
[CookieBench](https://cookiebench.com/) lists c15t's Next.js and React examples
at the top of its checked leaderboard; Cookiebot by Usercentrics was not listed
there, so this page does not assign it a CookieBench speed score.

> ⚠️ **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.

## Why c15t wins here

* c15t gives JavaScript, React, and Next.js teams direct APIs for consent state.
* c15t supports hosted, self-hosted, custom backend, and offline browser modes.
* c15t keeps consent records and policy state close to the product architecture.
* c15t includes script loading, iframe blocking, network blocking, and
  integration manifests.
* c15t lets teams own framework behavior, server rendering, and same-origin
  routing.

and server-side behavior. It keeps the cookie-banner path simple while giving
engineering ownership over the consent layer.
