c15t 2.0

Cookie banners are the internet's most hated UI element. They're slow, bloated, and give developers zero control. Every privacy popup slows your site down by milliseconds that cost you conversions. c15t exists because somebody finally said "enough."

c15t is the developer-first consent banner built for modern web apps. It's open source, works with Next.js and React out of the box, and gives you full control over script loading and consent management. Throw it in via CLI with npx @c15t/cli and you're cooking in 30 seconds. It supports integrations like Meta Pixel right off the rip—no wrestling with documentation or third-party scripts that tank your lighthouse scores. Version 2.0 just dropped with performance improvements that won't tank your Core Web Vitals.

Most cookie banners treat developers like enemies. c15t treats you like the professionals you are. It loads only what it needs, when it needs it, and respects user choices without throwing up walls. 1.7k developers already voted with their repos.

If you're shipping a Next.js or React app and still dealing with some clunky consent modal that adds 200kb to your bundle, try c15t. Your users won't notice the banner. Your lighthouse score definitely will.
