Cookie banners are usually an afterthought bolted onto a site with a script tag. c15t (@c15tdev) treats consent as part of the architecture: framework-agnostic, fully customizable, no vendor lock-in. openalternative.co/c15t

c15t: Open Source Alternative to Cookie Control, CookieYes and OneTrust

Open source consent management framework for modern web apps. Framework-agnostic, fully customizable, and performance-first with no vendor lock-in.

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.

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.

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.
