Preact Island

At less than 1.3kB minified, it adds negligible overhead, making it ideal for performance-sensitive embeds where every kilobyte counts, as shown in the bundle size comparisons.

Components automatically rerender when props change from multiple sources like element attributes or script tags, providing a dynamic experience without manual updates, demonstrated in the reactive props examples.

Supports rendering by CSS selector, inline placement, or via script attributes, offering developers versatile ways to integrate widgets into existing pages, as detailed in the API options.

Works seamlessly with React through preact/compat, allowing reuse of existing React components and hooks while reducing bundle size by up to 15x, per the README's bundle analysis.
