Show HN: Proa – a Rust web framework with fast SSR and multi-target rendering

Proa is a new Rust web framework designed for fast server-side rendering and multi-target output, allowing developers to write a single typed component that renders to HTML, Markdown, and other formats. The framework emphasizes performance, with benchmarks showing it renders 5.56ms p50 compared to React's 237ms, and includes a showcase of recreated applications like GitHub, Sentry, and Airbnb built with selective interactivity. Proa requires no JavaScript and offers a batteries-included approach with UI components styled after Shadcn.
