Open-source, lightweight consent SDK for React, Next.js and plain JavaScript, built by CookieChimp. MIT licensed.
  • Local mode, no account. Consent lives in a first-party cc_consent cookie. Your code owns the config.
  • Connected mode. Pass a CookieChimp projectId to sync the consent log, scanner categories, dashboard copy, translations, regional rules and styling. Your code config stays as the fallback.
  • No banner flash. The Next.js providers read the consent cookie on the server, so the first HTML already matches the visitor’s choice.
  • Blocks before consent. Script and iframe gating, runtime blocking, a network blocker, Google Consent Mode v2 and presets for common vendors.
  • IAB GPP (US) and TCF (EU), both opt-in and lazy.
  • Small. Size budgets are enforced in CI (docs/size.md).
The SDK never looks up a visitor’s location. It makes no geo-IP or external location request. Applications pass trusted region context, for example from their hosting platform’s headers.
