Love the focus on performance here. Most cookie banners feel like such a heavy 'tax' on LCP scores. How does c15t handle heavy script blocking without causing layout shift?

@rivra_dev you've got that part right! c15t avoids layout shift by not loading non-consented scripts in the first place, rather than loading a heavy blocker and swapping things around afterwards. the blocked scripts just stay out of the DOM this way

Hey Product Hunt! 👋
Christopher here, Creator of c15t and Founder of Inth.com.
c15t 2.0 is here. When it came to cookie consent, developers were forgotten about. Marketing and legal teams put banners on their sites that slow them down always feel detached from their UI. We first launched c15t a year ago to fix this and provide cookie consent compliance without sacrificing performance.
c15t 2.0 ships with;
- 89ms banner load speed (as benchmarked on Cookiebench.com)
- Policy Packs: fine tune regional consent behavior explicitly.
- Script loading v2: consent aware loading for analytics/marketing scripts.
- Dev tools: inspect consent states from anywhere in the world.
- c15t Skills: agents can install c15t to help implement, customize, and debug.
- New global standards: IAB TCF 2.3 and Global Privacy Control support.
- Apache 2.0 license: switched from GPL 3.0 for easier adoption.
Since launching, c15t has gained over 2 million npm downloads, (now a download every 4 seconds), 1.7k GitHub stars, and is used by some of the worlds best engineering teams that care most about performance, control, and getting compliance right.
We rebranded Consent.io, our official host and platform, to Inth.com and expanded our offering to get c15t launched faster and release other user privacy frameworks like our DSAR-SDK.
We're so excited to bring c15t 2.0 to you and hear how this changes what's possible for launching clean consent compliance on high performance sites.
