preact
A fast 4kB alternative to React with the same modern API, featuring components and a virtual DOM.
What is preact?
Preact is a fast, lightweight alternative to React for building user interfaces with components and a virtual DOM. It mirrors React's modern API—including hooks, JSX, and functional components—but at just 4kB, making it significantly smaller. It solves the problem of React's larger bundle size while maintaining compatibility, enabling developers to create efficient web applications without sacrificing developer experience.
Frontend developers building web applications who need a React-like experience with minimal bundle size, especially those working on performance-critical projects like progressive web apps, embedded widgets, or sites where load time is a priority.
Developers choose Preact over React for its tiny footprint and optimized performance, which reduces initial load times and improves runtime efficiency. Its near-perfect compatibility via `preact/compat` allows teams to leverage existing React knowledge and ecosystems while benefiting from a lighter alternative.
