coderpad.io does not allow embedding, so this is Google's rendering of the page.
Speed
Mobile performance score: 69
69/100Your mobile performance score is 69 (desktop: 99). Pages that score under 90 lose visitors before the first paint.
Render-blocking requests
900 ms4 files block the first paint until they finish downloading. Deferring or inlining them could save about 900 ms.
Improve image delivery
300 ms · 436 KiB6 images could be 436 KiB smaller with modern formats (WebP or AVIF) and sizes that fit a phone screen. Google estimates it would make the page about 300 ms faster on a phone.
1,580 HTML elements
The page has 1,580 HTML elements. Above 1,500, rendering and every interaction get slower on phones.
Use efficient cache lifetimes
100 ms · 79 KiB5 files are served with short cache lifetimes, so returning visitors download them again (79 KiB).
Minify JavaScript
150 ms · 4 KiB4 KiB could be saved by minifying JavaScript.
Reduce unused CSS
73 KiBAbout 73 KiB of CSS is downloaded but never applied on this page.
6 third-party services on the page
6 third-party services load with your homepage (Clearbit, JSDelivr CDN and Cloudflare and others), adding 82 KiB and 53 ms of main-thread time.
Phones get a much slower page than desktops
Desktop scores 99 but mobile only 69. A gap that wide usually means heavy scripts and images that hit phones hardest.
Legacy JavaScript
10 KiBPolyfills for old browsers add 10 KiB JavaScript that modern phones do not need.
Chained critical requests
Critical files load one after another instead of in parallel (3 chains). Preconnecting to key origins and preloading the hero image shortens the chain.
Forced reflow
Scripts make the browser recalculate the layout repeatedly while the page loads, which wastes processor time on phones.
Minify CSS
2 KiB2 KiB could be saved by minifying CSS.

Images and page weight
