Qwik

Qwik is the framework that actually solved the hydration problem. While Next.js and Astro bolt on clever workarounds, Qwik skips hydration entirely through "resumability" — your app picks up on the client exactly where the server left off, shipping roughly 1-2KB of JS for initial interactivity. The result: perfect Lighthouse scores and sub-second TTI without thinking about it.

If you're building content-heavy sites, e-commerce, or anything where Core Web Vitals drive revenue, Qwik is your unfair advantage. It outperforms Next.js on every speed metric that matters. SvelteKit and Astro are the closest alternatives — both fast, but neither eliminates hydration. On the commercial side, Vercel's Next.js has more ecosystem support and jobs.

The catch: Qwik's ecosystem is still small. Finding Qwik-specific libraries, hiring Qwik developers, or getting Stack Overflow answers takes more effort than React. And if you're deep in the React ecosystem, the mental model shift is real — this isn't just a new framework, it's a new paradigm.
