Qwik Goals
General-purpose
Qwik can be used to build any type of web site or application
Instant-on
Unlike other frameworks, Qwik is resumable which means Qwik applications require 0 hydration. This allows Qwik apps to have instant-on interactivity, regardless of size or complexity
Optimized for speed
Qwik has unprecedented performance, offering sub-second full page loads even on mobile devices. Qwik achieves this by delivering pure HTML, and incrementally loading JS only as-needed.
Getting Started with Qwik
Does page speed really matter?
Put simply: slow sites deter visitors, costing businesses millions. Fast sites have better SEO, better UX, and are more profitable.
Some examples from web.dev:
| Every 100ms faster → 1% more conversions For Mobify, every 100ms decrease in homepage load speed worked out to a 1.11% increase in session-based conversion, yielding an average annual revenue increase of nearly $380,000. | 50% faster → 12% more sales When AutoAnything reduced page load time by half, they saw a boost of 12% to 13% in sales. |
| 20% faster → 10% more conversions Retailer Furniture Village audited their site speed and developed a plan to address the problems they found, leading to a 20% reduction in page load time and a 10% increase in conversion rate. | 40% faster → 15% more sign-ups Pinterest reduced perceived wait times by 40% and this increased search engine traffic and sign-ups by 15%. |
| 850ms faster → 7% more conversions COOK reduced average page load time by 850 milliseconds which increased conversions by 7%, decreased bounce rates by 7%, and increased pages per session by 10%. | 1 seconds slowness → 10% less users The BBC found they lost an additional 10% of users for every additional second their site took to load. |
