Cookie Crumbs - Cookie Consent

CookieCrumbs is a GDPR consent management platform for developers, founders, marketers and agencies. It replaces the cosmetic cookie banner with three things that work together: a website cookie scanner, a banner that blocks trackers until consent, and a consent log that holds up as proof.

The scanner loads every page of your site in a real browser, in each consent state, and records every cookie, script, pixel, iframe and storage key together with the page and script that set it. It matches them against a maintained tracker database, publishes the cookie declaration as JSON, HTML or Markdown in your languages, and re-scans daily, weekly or monthly. New trackers arrive as a Slack or email alert, blocked by default. In CI, cookiecrumbs scan --fail-on-unknown fails the build when an unclassified tracker appears.

The banner is one 21 kB gzipped file, loaded async, with no third-party requests and no layout shift. Seven layouts, ten templates, 25 languages, WCAG 2.2 AA, and Reject all as prominent as Accept all on the first layer. It sets Google Consent Mode v2 defaults to denied before any tag runs and applies the correct regime for the EU, UK, US states, Switzerland, Brazil and Quebec, including Global Privacy Control.

Every choice is stored with a timestamp, banner version, a hash of the texts shown and the categories granted, chained to the previous record. Exports are Ed25519-signed CSV or JSON. No IP address or user agent is stored beside a record.

Set up from the dashboard, the CLI, typed SDKs for Next.js, React, Astro, Nuxt and SvelteKit, or the MCP server for Claude Code and Cursor.
