Overview

Preact is a lightweight library that provides the core features of React in a much smaller package. It is designed to be a drop-in replacement for React in many cases, making it ideal for performance-sensitive projects.

Key Features

  • Tiny Size: Only 3kB (gzipped), compared to React's ~40kB.
  • React Compatibility: Works with most React libraries via preact/compat.
  • Fast Performance: Optimized for speed and low memory usage.
  • No Synthetic Events: Uses standard browser events for better performance and smaller size.

Use Cases

Preact is perfect for widgets, landing pages, and mobile-first applications where every kilobyte counts.
