About preact
What is preact?
preact is a fast, 3kB alternative to React, offering the same modern API and ecosystem. It allows developers to build high-performance web applications with a tiny footprint, ensuring faster load times and better user experience.
Who is preact for?
preact is ideal for developers and teams who want to build lightweight, high-performance web apps without sacrificing developer experience. It's great for projects where performance and bundle size are critical.

Key Benefits and Use Cases
With preact, you can achieve near-instant loading on mobile devices, build progressive web apps (PWAs) that score high on Lighthouse, and create reusable UI components with minimal overhead. It's also perfect for embedding in existing projects or building micro-frontends. Its compatibility with React means you can leverage a vast ecosystem of tools and components.
Key features

- High Performance — Virtual DOM diffing and optimized rendering deliver top-notch speed.
- Hooks Support — Use React hooks for state and lifecycle without context switching.
