Mindblowing Google PageSpeed Scores with Qwik
summary
Claims Qwik (from Builder.io) hits 100 Google PageSpeed scores by changing architecture: server renders HTML with listeners serialized into DOM so the client needs less than a kilobyte bootstrap and often under one millisecond to start. Runtime defers and lazy‑loads code per interaction, reducing unused JS to single‑digit percent in the demo and showing a 0.6 ms initial execution. Demo runs on Stackblitz, open‑source, and the built system resumes server state in the browser rather than replaying renders.
