Qwik

Web framework for building resumable, instant-loading applications. Delivers apps that boot with about 1kb of JavaScript regardless of size or complexity, using resumability instead of hydration so pages become interactive without client-side re-execution of server output.

Created by Miško Hevery and the team behind Angular, adopted by Builder.io, Reflect.app, and others. Qwik differs from React, Next.js, and Vue by skipping hydration entirely: the server serializes application state into HTML, and the client resumes execution on demand when users interact, rather than downloading and re-running the full app.

Key capabilities:

• Resumability: server-rendered output is serialized and resumed on the client with no hydration step
• Qwik City for file-based routing, layouts, SSR, and static generation
• Built on Vite for fast development, Vitest and Playwright for testing
• Optimizer that bundles based on real-user metrics for optimal code splitting
• Deployment to Vercel, Netlify, Deno, Cloudflare Workers, Express, and Node

Teams use Qwik for marketing sites, dashboards, and content-heavy apps where instant Time to Interactive and SEO matter. Developers familiar with React benefit from JSX, functional components, and reactive patterns while gaining a fundamentally different execution model that scales to large apps without hydration cost.
