Speed Kit

Baqend GmbH

Speed Kit is a performance-add-on that makes your website load instantly. Added as a JavaScript, it accelerates Plesk websites by 50–300%.


Speed Kit powers about 7,000 websites, serving 200 million users monthly, accelerated 3.6 billion euros of annual revenue and scaling 25,000 requests per second. By using Speed Kit, you’ll have the following benefits:

  • User Experience: Turn page speed into your competitive advantage.
  • SEO Ranking: Let the speed-based search rank boost your visibility.
  • Time on Site: Make your users stay longer and click more.
  • Conversion Rate: Grow e-commerce revenue and funnel metrics.
  • Bounce Rate: Reduce your marketing costs through lower bounce rates.


After activating the plugin, Speed Kit adds a Service Worker to your website. The Service Worker then reroutes all requests from your backend to a fast cache which is synchronized with your website. Speed Kit accelerates your website without any changes to the backend servers. Instead of re-engineering your server, network, and frontend performance, Speed Kit hooks into the traffic and accelerates it from the user side.

If you are using WP Toolkit, Speed Kit works as a one-click solution to accelerate your website. If you are not using WP Toolkit and your site has dynamic content, the setup needs to be done by a professional with the help of our installation wizard.

Baqend is a research spin-off from the University of Hamburg on the mission of building a web without loading times. The founders pioneered a novel approach to speed up the delivery of dynamic data. Speed Kit bundles years of this research in a plugin for large-scale e-commerce and brand websites, that is easily implemented by just a line of JavaScript code. Today, some of the leading European e-commerce players like Decathlon, Galeria, and Orsay already rely on Speed Kit to improve their conversion rates, user experience, and SEO ranking. Since the product’s speed uplift is cleanly proven by statistically sound A/B-tests, Baqend is one of the fastest-growing SaaS companies in Germany.
