# Set Up SpeedKit – Plesk Performance Extension (Baqend)

Set up SpeedKit in Plesk: installation, WordPress integration, Page Speed Analyzer, CDN caching & service worker – speed up your website.

**Quick answer:** SpeedKit is a Plesk extension by Baqend that speeds up websites by 50–300% via service worker and edge caching. Install: Plesk → Extensions → SpeedKit → Install → Configure. WordPress: one-click integration. Other CMS: embed JavaScript snippet.

## What is SpeedKit?

SpeedKit (by Baqend) is a Plesk performance extension that accelerates websites without backend changes. A **service worker** in the browser reroutes requests to a fast edge cache.

## SpeedKit vs. Cloudflare vs. nginx cache

SpeedKit excels at dynamic sites (WordPress, shops). Cloudflare is free for static assets + DDoS. nginx cache in Plesk works for simple static sites. See [website performance guide](/en/webspace/website-schneller-machen).

## Installation steps

Plesk → Extensions → Speed Kit → Configure. WordPress is detected automatically.

- Log in to Plesk → Extensions → search Speed Kit → Install
- Open your domain → Speed Kit → Install Speed Kit
- Configure Speed Kit → follow wizard
- WordPress: one-click integration. Other sites: paste JS snippet in head
- Configure cache policies, blacklist checkout/cart URLs

## Common issues

HTTPS required for service worker. Blacklist dynamic pages (cart, checkout). Clear browser cache after setup.
