Leptos Has a Free Rust Web Framework — Full-Stack Rust with React-Like Reactivity

A Rust developer wanted to build a web app. The options were: JavaScript (no thanks), WASM frameworks like Yew (limited), or server-rendered templates. None felt like modern React DX.

Leptos brings React-like reactivity to Rust. Components, signals, SSR, hydration - familiar patterns, Rust performance.

What Leptos Offers for Free

  • Fine-Grained Reactivity - Signals like SolidJS, in Rust
  • SSR + Hydration - Server-side rendering with client hydration
  • Components - JSX-like syntax with Rust type safety
  • Routing - File-based and programmatic routing
  • Server Functions - Call server code from client (like Next.js server actions)
  • WASM - Compiles to WebAssembly for client-side
  • Streaming - Stream HTML to client

Quick Start

use leptos::*;

#[component]
fn App() -> impl IntoView {
    let (count, set_count) = signal(0);
    view! {
        <button on:click=move |_| set_count.update(|n| *n += 1)>
            "Clicked: " {count}
        </button>
    }
}
Enter fullscreen mode Exit fullscreen mode
