Zest - Lightweight Cookie Consent Toolkit

Cookie Consent Made Simple

Zest is a lightweight, zero-dependency cookie consent toolkit for GDPR/CCPA compliance. At only ~9KB gzipped, it's a modern alternative to heavier solutions like Klaro (45KB) and Tarteaucitron (80KB).

Key Features

• Lightweight - Only ~9KB gzipped with zero dependencies
• Smart Script Blocking - Automatically blocks tracking scripts until user consents
• Cookie & Storage Interception - Queues blocked operations and replays when consent is granted
• Privacy Signals - Respects Do Not Track (DNT) and Global Privacy Control (GPC)
• 12 Languages - Built-in support for EN, DE, ES, FR, IT, PT, NL, PL, UK, RU, JA, ZH
• Beautiful UI - Customizable banner, modal, and floating widget with dark mode
• Developer-Friendly - Simple API, events, and callbacks for full control

Quick Start

<script>
  window.ZestConfig = {
    position: 'bottom-right',
    theme: 'auto',
    accentColor: '#0071e3',
    policyUrl: '/privacy-policy'
  };
</script>
<script src="https://unpkg.com/@freshjuice/zest"></script>

That's it! Zest will automatically show the consent banner and block known tracking scripts.
