Warning
Dioxus 0.5 (currently in master) contains massive breaking changes and is not compatible with Dioxus 0.4
Dioxus is a portable, performant, and ergonomic framework for building cross-platform user interfaces in Rust.
fn app() -> Element {
let mut count = use_signal(|| 0);
rsx! {
h1 { "High-Five counter: {count}" }
button { onclick: move |_| count += 1, "Up high!" }
button { onclick: move |_| count -= 1, "Down low!" }
}
}
Dioxus can be used to deliver webapps, desktop apps, static sites, mobile apps, TUI apps, liveview apps, and more. Dioxus is entirely renderer agnostic and can be used as a platform for any renderer.
If you know React, then you already know Dioxus.
Unique features:
- Desktop apps running natively (no Electron!) in less than 10 lines of code.
- Incredibly ergonomic and powerful state management.
- Comprehensive inline documentation - hover and guides for all HTML elements, listeners, and events.
- Blazingly fast 🔥🔥 and extremely memory efficient
- Integrated hot reloading for fast iteration
- First-class async support with coroutines and suspense
- And more! Read the full release post.

Why Dioxus?
There's tons of options for building apps, so why would you choose Dioxus?
Well, first and foremost, Dioxus prioritizes developer experience. This is reflected in a variety of features unique to Dioxus:
- Autoformatting of our meta language (RSX) and accompanying VSCode extension
- Hotreloading using an interpreter of RSX for both desktop and web
- Emphasis on good docs - our guide is complete and our HTML elements are documented
- Significant research in simplifying
Dioxus is also a very extensible platform.
- Easily build new renderers by implementing a very simple optimized stack-machine
- Build and share components and even custom elements
So... Dioxus is great, but why won't it work for me?
- It's not fully mature yet. APIs are still shifting, things might break (though we try to avoid it)
- You need to run in a no-std environment.
- You don't like the React-hooks model of building UIs
