Qwik
FreeFramework for instant-loading web applications with resumability.
What does this tool do?
Qwik is a modern web development framework designed to solve performance bottlenecks in web applications through a revolutionary approach called 'resumability'. Unlike traditional frameworks that require full JavaScript hydration, Qwik allows applications to become instantly interactive by serializing application state and allowing components to resume execution precisely where they left off. This means dramatically faster initial page loads and significantly reduced JavaScript bundle sizes, making web applications feel nearly instantaneous.
