A tiny concurrent UI library with fiber architecture for building performant web applications.
Fre is a tiny concurrent UI library that implements fiber architecture for building performant web interfaces. It provides React-like APIs including hooks, virtual DOM, and Suspense while focusing on minimal bundle size and concurrent rendering capabilities. The library solves the problem of UI blocking by enabling time-sliced updates through coroutine scheduling.
Frontend developers building modern web applications who need React-like functionality with better performance characteristics and smaller bundle sizes. Particularly suitable for developers prioritizing concurrent rendering and minimal dependencies.
Developers choose Fre for its combination of familiar React patterns with superior performance through concurrent rendering and extremely small bundle size. It offers a complete feature set including hooks, Suspense, and virtual DOM while being significantly lighter than alternatives.

Implements coroutine scheduling for time-sliced updates to prevent UI blocking, enabling smooth user experiences as emphasized in the README's features.
Maintains an extremely small footprint while offering hooks and virtual DOM, evidenced by the brotli size badge showing optimized implementation.
Provides hooks like useState and useEffect, Suspense, and Fragments, making it easy for React developers to adopt, as shown in usage examples.
Uses a keyed diff algorithm that supports pre-processing and SSR hydration, contributing to performance optimizations highlighted in the features.
Has a smaller community and fewer third-party integrations compared to established frameworks like React, which can slow development and limit tooling options.
The README is brief and links to an external wiki, lacking in-depth examples and comprehensive guides for complex use cases or troubleshooting.
Requires manual setup for JSX in build tools like Vite, as shown in the README, adding complexity compared to out-of-the-box solutions in React.
As a smaller project with fewer contributors, it may experience more breaking changes or unpredictable maintenance, risking long-term reliability.
