Waku: The Minimal React Framework

Waku is a minimal React framework designed for building performant web applications with a focus on React Server Components (RSC) and React 19 features. Currently in its v1.0.0-alpha.7 release, it is under active development with frequent alpha releases that may introduce breaking changes, particularly in adapters and internal APIs. Waku is optimized for marketing sites, blogs, headless commerce, and web apps where a lightweight footprint and full-stack React composability are key differentiators. Unlike heavier frameworks, it emphasizes a lean approach, prioritizing a fun developer experience with modern React paradigms. It supports all the latest React 19 features, including server components and actions, aiming for smaller client bundle sizes by leveraging server-side rendering extensively. It requires Node.js `^24.0.0`, `^22.12.0`, or `^20.19.0`.
