# Copy of Performance Impact

Poppin is built to be fast, efficient, and invisible to your core site performance.

* **Lightweight script:** The main script is \~24 kB gzipped — significantly smaller than tools like Intercom or Crisp (\~100-150 kB).
* **Async loading:** It loads in the background without blocking your page rendering.
* **No backend dependency:** The embed works entirely on the frontend. No server-side setup required.
* **No layout shift:** It runs as a passive layer, without interfering with your existing DOM or causing reflows.
