Our verdict on c15t

c15t is an open-source cookie consent management platform for JavaScript, React, and Next.js applications. It combines consent banners and preference dialogs with headless APIs, framework components, regional policy handling, and consent-aware loading for scripts, iframes, network requests, analytics, advertising pixels, tag managers, and chat widgets. Developers can choose a managed backend through Inth, deploy the backend on their own infrastructure, or use browser-only offline mode. It is best suited to teams that need implementation flexibility and direct control over consent behavior.

Its strongest area is technical coverage. c15t supports jurisdiction-based policy resolution, geolocation, durable consent records, audit logging, server-side consent visibility, and interfaces for Google Consent Mode v2 and IAB TCF 2.3. Blocking extends beyond scripts to iframes and network requests, which gives teams several enforcement points across a web application. The integration list includes Google Tag Manager, Google Analytics 4, Google Ads, Meta Pixel, TikTok Pixel, LinkedIn Insights, Microsoft UET, Adobe Analytics, Amplitude, PostHog, Segment, Mixpanel, Microsoft Clarity, Hotjar, and Intercom.

Deployment choice is a major part of the product’s appeal. Hosted, self-hosted, custom, and offline client modes can accommodate different infrastructure and data-handling preferences, while the open-source model gives developers a flexible foundation. The trade-off is that c15t is more implementation-oriented than a simple, site-builder-style banner tool. Teams should pick it when they need APIs, framework components, blocking, jurisdiction logic, and durable records; organizations seeking only a lightweight consent banner may prefer a narrower product.
