Preact
Building web interfaces where lightweight bundle size is critical (e.g., for slow connections), Projects where React compatibility is needed but with a smaller footprint
It's a nearly drop-in React replacement that prioritizes speed and small size, ideal for performance-focused web projects.

“I built Kamod Hooks, a Preact hooks library inspired by and ported from ahooks. The goal is to bring a broad set of practical React-style hooks to the Preact ecosystem, while keeping the package lightweight and Preact-native.”

“it's been fantastic. Maybe 50 lines of code to replicate reagent atoms with preact/signals, all the benefits, and much much faster. Very happy that there is react-like library so devoted to first class support of signals.”
