What it does
The open-source cookie consent standard used by teams that care about performance, control, and compliance. c15t runs inside your app. No scripts. Minimal load. Jurisdiction aware consent logic. The fastest cookie banner available, by Inth.com.
c15t is an open-source consent management platform for React, Next.js, and modern JavaScript applications. It provides consent UI, consent-aware script loading, and self-hosted or managed deployment options.
c15t is the open source web standard for managing consent and script loading. Built for modern web apps with full developer control. Paste it into your coding agent. It starts with an Inth hosted project, then inventories, implements, and verifies the complete consent flow. Native components, headless primitives, and resource controls give you a complete consent system without handing the experience to a black-box script. Minimal runtime overhead, a small tree-shakable bundle, and no blocking third-party script between your visitor and the page. Use your own components, design tokens, themes, and interaction patterns. c15t adapts to the product instead of fighting it. Keep banner copy,…from c15t.com

Talanoa▲343Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
