Sycamore is a next gen Rust web UI library powered by fine-grained reactivity. use sycamore::prelude::*; #[component] fn Counter(initial: i32) -> View { let mut value = create_signal(initial); view! { button(on:click=move |_| value += 1) { "Count: " (value) } } } Features Effortless Performance Sycamore is built on top of Rust and WebAssembly , giving you full control over performance. Sycamore's reactivity system is fine-grained, meaning that only the parts of your app that need to be updated will be.

  Hi 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…

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
