Qwik Go For 100
summary
Claim: Qwik automatically keeps Core Web Vitals high as an app scales by shipping only the tiny code needed for interactive nodes. It uses the Qwik optimizer (Rust) to emit QRL segments, leverages resumability and JS streaming, and a ~2 KB inline loader to queue events. A vanilla-extract styled‑components plugin demonstrates real integration, preload probabilities reduce latency from hundreds of small files, and documentation sites score near 100 on performance metrics.
