Highlights: • Google Maps & YouTube support • Configurable consent controls toolbar • useConsentScript for custom SDKs • 8 new script providers • CSP nonce support • Stronger IAB TCF handling • Backend reliability improvements Full changelog: c15t.com/changelog/2.2.0
c15t appears in 59% of Opus 5’s recommendations vs 25% in Opus 4.8, a 2.4x jump. Soon, c15t will be the first option every model recommends.
Let's get back to installing cookie banners.
In c15t, script helpers return plain Script objects, so analytics, pixels, and tag managers sit beside app-specific scripts. One startup path. One consent lifecycle. Fewer mystery tags.
When a product adds another analytics vendor, the messy part is not the import. It is where startup lives.
Yesterday we hit 3 million download of @c15tdev. 🤯
Pretty cool cookie banner if you ask us
Expanding into Europe or beyond? Ethan Byrd, Founder of @primitive, says Inth was a no-brainer for consent compliance across regions. Privacy compliance that keeps up with how you ship.

We don't use the internet anymore. All we do is review data processing agreements.
I'm in Europe: land of the content-blocking full-screen cookie banner. How do you all use the internet like this all the time!?
Seems legit.
Your agent can install and configure your consent banner. Install c15t skills: pnpm dlx @c15t/cli skills
