Metomic is a GDPR, CCPA and ePrivacy compliant cookie widget, that is designed to increase user trust and opt-in. Their values show immeditelly with beautiful minimalistic and fully customizable design, giving you ability to change color, button style, position on screen, plus custom prompt and accept text, but still maintain minimal look and appear trustworthy. They are currently supporting 21 languages, but are constantly adding new ones and if you want white-labeled Metomic, you'll have to upgrade to ther Pro plan, which costs £10 (approximatelly $13).
Their cookie widget embed script can be added in two ways, either by copy pasting the snippet into the head of your webpage or by using GTM (Google Tag Manager).
With Script Blocking, Metomic can block scripts that should not run until the consent to them has been given. You can choose between manual (the fundamental way that blocks problematic scripts from loading instantly) and autoblocking, that blocks scripts automatically- without the need for code changes.
