Leptos is a full-stack Rust framework with fine-grained reactivity, SSR, and hydration. Write your frontend AND backend in Rust — with a React-like component model that's faster than virtual DOM. Why Leptos? Fine-grained reactivity — no virtual DOM diffing, signals update exactly what changed Full-stack — SSR, hydration, server functions — all in Rust WASM frontend — compiles to WebAssembly for near-native speed Type-safe — share types between server and client Quick Start cargo install cargo-leptos cargo leptos new --git leptos-rs/start cd myapp cargo leptos watch Components and Signals use leptos :: * ; #[component] fn Counter () -> impl IntoView { let ( count , set_count ) = create_signal ( 0 ); view! { < div > < p > "Count: " { count } </ p > < button on : click = move | _ | set_count .update (| n | * n += 1 ) > "Increment" </ button > </ div > } } Derived Signals #[component] fn App () -> impl IntoView { let ( count , set_count ) = create_signal ( 0 ); let doubled = move || count
