# Does Powerbeans Slow Down My Site?

> How Powerbeans widgets load asynchronously from a global CDN with 30-day browser caching to protect your page speed and Core Web Vitals scores.

A common concern before embedding any third-party widget is whether it will drag down page speed. Powerbeans widgets are built to have no meaningful impact on your page speed or Core Web Vitals.

## Asynchronous loading

Every widget script (Audio Player, Playlist, Text Summaries) loads **asynchronously** — it runs independently of your page's main thread and critical rendering path, so it never blocks or delays your page render.

## CDN delivery and caching

Widget assets are served from a global CDN and **cached in the browser for 30 days** after a reader's first visit, so returning visitors load the widget without a repeat trip to Powerbeans' servers.
