[tarteaucitron.js](https://github.com/AmauriC/tarteaucitron.js/) is a
long-running open-source tool with a large service catalog. Its public docs
emphasize detection, blocking, open-source installation, and Consent Mode support
through options such as `googleConsentMode`.

c15t is the better starting point when consent affects app runtime, backend
records, framework code, or server behavior. tarteaucitron.js is useful when a
large public service catalog is the main requirement.

> ⚠️ **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 teams JavaScript, React, and Next.js packages with TypeScript-first
  APIs.
* c15t supports hosted and self-hosted backend records instead of browser-only
  storage.
* c15t can coordinate scripts, iframes, and network requests through one consent
  layer.
* c15t policy packs keep regional behavior close to the consent platform.
* c15t fits app architectures where consent affects startup, routing, and server
  state.

## Comparison

|Area|c15t|tarteaucitron.js|
|--|--|--|
|Primary shape|Application consent platform|Script and service catalog|
|Framework support|First-class JavaScript, React, and Next.js packages|Script-first setup|
|Backend records|Hosted or self-hosted records|Client-side storage unless extended|
|Service catalog|Integration manifests and custom integrations|Large public service catalog|
|Consent Mode|Google tag helper|`googleConsentMode` option|
|SSR awareness|Available through c15t framework packages|Client-side by default|

## Bottom line

Start with c15t when coordinating third-party services. The initial job may look
like service loading, but consent quickly affects app state, backend records,
regional policy, analytics, ads, and server rendering.
