Neiki's Cookie Banner is a lightweight, drop-in cookie consent solution for any website that needs to comply with GDPR, ePrivacy, and similar privacy regulations — without dragging in a heavy third-party SDK or tying your site to a paid SaaS.
It is built from the ground up in vanilla JavaScript with zero dependencies, so it works on any stack — from a static HTML page to a WordPress theme, Laravel app, Next.js site, or anything in between. Drop in one file and you have a fully functional, accessible, themeable consent banner in under a minute.
