Choose React if you need production stability, extensive third-party libraries, abundant hiring talent, and maximum community support—it remains the industry standard for enterprise and startup applications. Choose Qwik if you're building performance-critical applications where instant interactivity is paramount, you can afford limited ecosystem support, and you want to experiment with resumable frameworks.

Learn React if job marketability is important—18,500+ global positions vs 145 for Qwik. React dominates 42.7% of the frontend market. However, Qwik is excellent for understanding modern performance optimization techniques and resumability concepts. Many professionals learn React first, then Qwik as a specialized tool.
Qwik uses 'resumability' instead of hydration. React downloads JavaScript, parses it, then re-executes component logic on the client (hydration). Qwik serializes component state and event handlers at build time, allowing the browser to 'resume' where the server left off with zero JavaScript execution overhead initially. This eliminates React's 2.8s TTI and achieves 0.8s instead.
Is Qwik production-ready for enterprise apps?
Technically yes—Qwik powers the Builder.io website and ~500 documented production sites. However, the tiny ecosystem (8k vs React's 2.1M packages) means you'll build many features custom. React has 2.5M+ production applications and 11 years of proven patterns, making it safer for enterprise teams that need off-the-shelf solutions and abundant hiring talent.
Partially. Qwik can integrate React components via Qwik's integration layer, but you lose many resumability benefits. Direct npm package compatibility is limited to ~8k packages vs React's 2.1M. If heavy third-party dependency usage is required, React remains the better choice.
What's the real-world performance difference for typical apps?
For a typical e-commerce site, React might load interactive product filters in 2.8 seconds, while Qwik achieves 0.8 seconds—a 71% improvement. This matters most for performance-critical applications (news sites, e-commerce, mobile-first contexts). For internal dashboards or admin tools, the difference is often negligible in user experience.
