[Silktide Consent Manager](https://github.com/silktide/consent-manager) is a
free, open-source banner with Google Consent Mode v2 examples. Its docs show
consent defaults, `gtag` mappings, a `stcm_consent_update` dataLayer event, and
both CDN and self-hosted deployment.

c15t is the better starting point when Consent Mode needs to connect to app
state, backend records, policy packs, or React and Next.js APIs. Silktide is a
good fit for a free client-side banner that can stay browser-local.

> ⚠️ **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 can start in JavaScript or offline mode and grow into hosted or
  self-hosted records.
* c15t includes React and Next.js APIs for app-owned consent state.
* c15t supports script loading, iframe blocking, network blocking, and policy
  packs.
* c15t keeps Google Consent Mode work connected to the same consent model used
  by the rest of the app.
* c15t gives teams room to add durable consent records and server-side state.

setup connected to a platform that can support application state, backend
records, regional policy, and framework behavior.
