Cookie Consent Generator

Build a self-contained cookie consent banner: configurable cookie categories, banner text, position/style, and colors, with a live sandboxed preview and a copy/download-ready HTML+CSS+JS snippet that persists consent in localStorage and exposes it via window.getCookieConsent() and a cookieconsentchanged event.

This generates a consent UI and a storage/gating mechanism only — it is not legal advice.It does not by itself make your site GDPR/CCPA/ePrivacy compliant. You are responsible for actually gating your tracking/analytics/marketing scripts behind window.getCookieConsent() (or the cookieconsentchanged event) and for reviewing the rules that apply to your site.

Paste the generated snippet before </body> on every page that needs it. Gate any tracking/analytics/marketing script behind window.getCookieConsent().yourCategoryKey (or listen for the cookieconsentchanged event on document) — the banner itself only records the visitor's choice in localStorage and does not load or block anything on its own. Use the preview's "Manage Cookie Preferences" button to test re-opening the banner, and "Reset consent (dev)" to clear the stored choice and see the first-visit state again.

Frequently asked questions

How do I create a cookie banner without a third-party library?

Configure categories, text, position and colors, preview it live, then copy or download the self-contained HTML, CSS and JS snippet.

How does my site read the visitor's choice?

The snippet stores consent in localStorage and exposes it via window.getCookieConsent() and a cookieconsentchanged event.

Does the banner make my site GDPR compliant?

Not by itself. It collects and exposes consent, but you must make your scripts actually respect it.

Is my data uploaded to a server?

No. This tool runs entirely in your browser — your input is processed locally on your device and is never uploaded or stored on a server.
