Sycamore is a reactive library for creating web apps in Rust and WebAssembly.
#[component]
fn Hello<G: Html>(cx: Scope) -> View<G> {
view! { cx,
p { "Hello World!" }
}
}
- Lightning Speed: Sycamore harnesses the full power of Rust via WebAssembly, giving you full control over performance.
- Ergonomic and Intuitive: Write code that feels natural. Everything is built on reactive primitives without a cumbersome virtual DOM.
- No JavaScript: Had enough of JavaScript? So have we. Create apps using Sycamore without touching a single line of JS.
Documentation
Sycamore is extensively documented:
- Getting Started: How to write your first Sycamore app.
- Reactivity: Find out how to use Sycamore's powerful reactive primitives.

Examples
Sycamore has many examples for your reference in the
examples/
directory. Be sure to
check them out!
sycamore-rs.netlify.app
Viewing on All the examples are hosted under sycamore-rs.netlify.app/examples/<example_name>
with
<example_name>
being the name of the example you want to view. For instance, the todomvc
example
is hosted on
sycamore-rs.netlify.app/examples/todomvc
.
Building Locally
All the examples can also be built locally using Trunk. For instance, the
following command builds and serves the todomvc
example:
cd examples/todomvc
trunk serve
Now open up localhost:8080
in your browser to see "Hello World!".
Perseus
Perseus is a fullstack framework built with Sycamore. Think NextJS or SvelteKit but with no JavaScript. Everything from backend to frontend is built with pure Rust!
Alternatives?
Don't think Sycamore is for you? Thankfully, there are plenty of alternatives!
- SolidJS: A declarative, efficient and flexible JavaScript
library for building user interfaces
Solid is a JavaScript library which greatly inspired Sycamore. Many concepts such as fine-grained reactivity and components as factory functions were borrowed from Solid. If you don't mind working with JavaScript (or TypeScript), go check it out! - Yew: Rust / Wasm framework for building client web apps
Yew was also a big inspiration for Sycamore. Yew employs a VDOM and has a MVU (Elm) architecture. If you think that's for you, take a look! - MoonZoon: Rust Fullstack Framework
MoonZoon also champions the no VDOM paradigm and uses dominator as its underlying DOM layer. MoonZoon is a fullstack framework making it easier to combine frontend and backend code with minimal boilerplate.
