WebUI is not a web-server solution or a framework, but it allows you to use any web browser as a GUI, with your preferred language in the backend and HTML5 in the frontend. All in a lightweight portable lib.
- Parent library written in pure C
- Lightweight ~200 Kb & Small memory footprint
- Fast binary communication protocol between WebUI and the browser (Instead of JSON)
- Multi-platform & Multi-Browser
- Using private profile for safety
Examples are found in examples/ and can be run with cargo run --example <example_name>.
- Add
webuito your dependencies inCargo.toml:
webui = { git = "https://github.com/webui-dev/rust-webui/", branch = "main" }
# Or by git tag
webui = { git = "https://github.com/webui-dev/rust-webui/", tag = "v2.4.2" }
# Or by git commit
webui = { git = "https://github.com/webui-dev/rust-webui/", rev = "a1b2c3d4" }-
Then bring in the static WebUI static release or build action file for your platform and place it in your project's root directory.
-
That's it!
use webui_rs::webui;
pub fn main() {
let win = webui::Window::new();
win.show("<html><body><h1>Hello, World!</h1></body></html>");
webui::wait();

Web application UI design is not just about how a product looks but how it works. Using web technologies in your UI makes your product modern and professional, And a well-designed web application will help you make a solid first impression on potential customers. Great web application design also assists you in nurturing leads and increasing conversions. In addition, it makes navigating and using your web app easier for your users.
Today's web browsers have everything a modern UI needs. Web browsers are very sophisticated and optimized. Therefore, using it as a GUI will be an excellent choice. While old legacy GUI lib is complex and outdated, a WebView-based app is still an option. However, a WebView needs a huge SDK to build and many dependencies to run, and it can only provide some features like a real web browser. That is why WebUI uses real web browsers to give you full features of comprehensive web technologies while keeping your software lightweight and portable.
Think of WebUI like a WebView controller, but instead of embedding the WebView controller in your program, which makes the final program big in size, and non-portable as it needs the WebView runtimes. Instead, by using WebUI, you use a tiny static/dynamic library to run any installed web browser and use it as GUI, which makes your program small, fast, and portable. All it needs is a web browser.
