The banners are climbing 🧗 More than 2,600 c15t consent banners have been tracked by Wappalyzer. Developers are done with slow, bloated vendor scripts. c15t runs at 89ms, lives in your codebase, and is fast to ship.

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 CookieYes, Termly and iubenda

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

Look, c15t was the start of where Inth it is today...6 million downloads later. Inth now helps you automate your privacy compliance by catching privacy risks in your codebase 🙏

This is the Inth we always wanted. Inth now checks your codebase, website and every PR, then helps you fix privacy risks before they become blocked deals or expensive problems. Run a free privacy scan: inth.com Go break it.

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.

When a product adds another analytics vendor, the messy part is not the import. It is where startup lives.

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.

When AI agents are writing and deploying your code, who handles compliance? At Vercel Ship London this week, @willde_ath asked builders how they’re thinking about agents, privacy, and compliance.

We don't use the internet anymore. All we do is review data processing agreements.
