Generate cookie consent banner HTML/CSS/JS with consent categories, preference storage, and GDPR-compliant flows.
This tool assembles the HTML, CSS, and JavaScript for a cookie consent banner: the visible notice, a preference panel broken into consent categories (typically necessary, functional, analytics, marketing), and a script layer that records which categories a visitor accepted and keeps the choice for later visits. The output is static code meant to be pasted into a site, not a hosted widget. What people most often get wrong: it hands you the front-end mechanics and storage, but it can't inspect your site's actual scripts, so wiring analytics or ad tags to actually respect the stored choice, and confirming that satisfies GDPR/ePrivacy in your jurisdiction, is left to you.
You specify which consent categories the banner should offer - usually 'necessary' as an always-on, non-optional entry, plus optional ones such as functional, analytics, and marketing. The generator turns that list into matching toggles in the preference panel and into corresponding keys in the generated JavaScript consent object, so the panel, the code, and the stored record all use the same category names.
Once a visitor makes a choice, the generated script writes it to the browser (cookie or local storage) so the banner does not reappear on the next page load, and it exposes a check per category that you place around the tag or script you want gated - for example, only loading an analytics snippet if that category was accepted. It does not audit or modify your existing third-party scripts for you.
No. It generates the notice, category toggles, and consent-storage code, but compliance also depends on genuinely blocking non-essential cookies/scripts until consent is given, having a documented legal basis, and honoring withdrawal and data-subject requests - none of which the generated code alone guarantees. Treat it as a starting point, not a compliance certification.
Yes - the categories are inputs to the generator, so you can add, remove, or rename them (drop marketing, add a 'personalization' category, etc.) and regenerate the banner, matching toggles, and storage keys. If you already deployed the old version, re-run it and redeploy; existing visitors' prior stored consent won't retroactively include a newly added category.
