c15t is an open-source, developer-first consent management platform (CMP) for cookie banners, privacy preferences, consent storage, and consent-aware script loading. It ships headless JavaScript/React/Next.js packages plus a self-hostable backend API for consent records, audit logging, and policy management.

Use cases

add a GDPR cookie consent banner to a React or Next.js app
block analytics and marketing scripts until users grant consent
self-host a consent management API with audit logging on my own infrastructure
manage Google Consent Mode and IAB TCF consent signals
show consent-gated YouTube or Google Maps embeds
replace OneTrust or Cookiebot with an open-source CMP
let users customize cookie preferences by category

When to choose

you need consent state, script gating, and consent records inside your own app rather than a black-box script tag
you want React/Next.js components, hooks, and headless primitives with full styling control
you want to self-host consent storage and policy management on Node, Bun, Deno, or Cloudflare Workers
performance matters and you want to avoid blocking third-party CMP scripts

When to avoid

you need a guaranteed legal compliance solution without any policy work on your side
you want a fully managed, zero-code hosted CMP with vendor legal guarantees
your site is a simple static page where a tiny vanilla banner suffices
