[Usercentrics Web CMP](https://usercentrics.com/us/) is a hosted consent
management platform. Its docs cover direct implementation, markup guidance,
auto-blocking, service rules, and platform-managed consent workflows.

c15t is the better starting point when app-integrated consent state, backend
records, framework behavior, and deployment control matter. Usercentrics is
useful when a hosted Web CMP and platform-managed rules are the priority.
[CookieBench](https://cookiebench.com/) also lists c15t's Next.js and React
examples above Usercentrics 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.

## Why c15t wins here

* c15t supports JavaScript, React, and Next.js with first-class APIs.
* c15t can run hosted, self-hosted, against a custom backend, or offline.
* c15t keeps consent records and server-visible consent state available to the
  product.
* c15t supports policy packs, script loading, iframe blocking, and network
  blocking.
* c15t avoids making a SaaS-first control plane the default owner of consent
  behavior.

framework code. It keeps operational needs compatible with a developer-owned
consent layer.
