CJakCiasteczko is a lightweight cookie consent banner with native Google Consent Mode v2 support. Under 12 KB, you paste a single tag and your site is GDPR compliant, with no slowdown and no visual clutter.
It is a consent management platform (CMP) that reconciles legal requirements with site performance. A scanner automatically detects cookies, scripts and trackers, the banner collects consent in granular categories, and every user decision is recorded so you can prove valid consent during an audit.
Technically it is plain TypeScript with no frameworks: under 12 KB gzipped, first paint under 60 ms and zero layout shift. A hard size budget is enforced in CI, so the banner has no impact on Core Web Vitals.
Everything a modern website needs to collect consent legally and fast.
ad_storage, ad_user_data, ad_personalization and analytics_storage wired in by default. Denied values are sent before any tag fires and updated immediately after the user decides.
Opt-in by default in the EEA, granular consent categories and a consent log that lets you prove the user gave informed consent.
No framework, no jQuery, no bloat. A size budget enforced in CI means zero impact on page speed and Core Web Vitals.
Banner, modal and floating layouts, brand colors and fonts. Set it up once and the banner looks like a natural part of your site.
Strict opt-in for EEA visitors and a soft notice outside the EU, without writing a single line of custom logic.
Promise-based getConsent(), onConsentChange(), showPreferences() and ready(), fully typed in TypeScript. Plus a GTM template, a WordPress plugin and a Shopify app.
Three steps: create an account and add your domain, let a one-to-two-minute scan detect cookies and trackers, then paste one script tag into the head. The banner shows up right away and default Consent Mode values reach Google before any other tag.
Finally you adjust colors, copy and region rules, watch your opt-in rate and stay compliant on autopilot.
For anyone who spends money on ads or takes analytics and site speed seriously.
Without proper Consent Mode v2, Google Ads loses conversions and remarketing. CJakCiasteczko closes the measurement loop exactly the way Google requires.
Ready-made plugins for WordPress, WooCommerce, Magento and a Shopify app. Compliance without a developer and without slowing the store down.
One snippet for every stack, an API and webhooks. You roll out a CMP that never triggers tickets about broken layouts or slow pages.
We built it because we have been shipping websites for well over a decade and wanted a CMP that is fast, good looking and technically honest. We run it in production on aveneo.pl, so every release is tested on ourselves first.
Start free for 30 days. The scan shows you which cookies and trackers you have today, and the rollout is literally one tag.
