Preact
3KB React alternative. Worth evaluating where bundle size matters.
Preact implements the React API in 3KB. For lightweight widgets, embedded components, and performance-constrained environments, the size reduction is significant. The compatibility layer means most React libraries work without modification.
The trade-off is ecosystem risk. Preact tracks React's API but doesn't drive it. When React introduces new features, Preact follows — sometimes with gaps. For full applications, React is the safer bet. For isolated components where kilobytes matter, Preact deserves evaluation.
