What is Proa?
Proa is a Rust web framework designed for building high-performance web applications. It uses a single typed component model to render multiple output formats, including HTML, Markdown, and custom targets, from the same codebase. The framework emphasizes speed and reduces client-side JavaScript by defaulting to server-side rendering.
The package includes Proa UI, a collection of prebuilt components like tables, buttons, cards, calendars, and charts. These components are written in typed Rust, live directly in the developer repository, and support theming and composition. Many components ship as pure HTML or CSS without requiring JavaScript execution in the browser.
Proa supports an island architecture pattern, allowing developers to add interactivity only where needed. Benchmarks on the site claim significantly faster render times compared to traditional React server rendering. The project is hosted on GitHub and provides documentation, examples, and a showcase of applications built with the framework.
