Xilem – An experimental Rust native UI framework (github.com)

Xilem is an experimental Rust native UI framework from linebender that uses a React/SwiftUI/Elm-style reactive approach to keep a lightweight view tree and update the rendered UI as that tree changes. It’s paired with the Masonry crate, which provides a retained widget tree and handles event/update passes, while Xilem offers the higher-level reactive programming model. The project runs on common Rust GUI and graphics libraries (winit for windows, wgpu/Vello for 2D rendering, and Parley/Fontique for text) and includes a web backend as well.
