Lighthouse

Version 4.1.1 has been released! | Documentation

This version adds a security module and a firewall! Get Lighthouse to improve your WordPress website’s performance and also protect you from malware!

Note: This plugin requires PHP 7 or higher and (optionally, for best performance) WordPress 6.0 or higher!

Notice: Lighthouse is removing the Core Web Vitals and the CrUX features.

Read the announcement here.

Lighthouse is a performance tuning plugin, removing lots of default WordPress behaviour, such as filters, actions, injected code, native code and third-party actions.

Increase your site loading speed up to 300%

For a WordPress installation to work as expected, load fast and error-free, it needs a bit of cleanup in order to help the browser cache the requested content and the caching plugins to work with 100% efficiency.

With Lighthouse, you save over $480 in over 10 hours of coding by a web developer, which you would need pay to do it for your website, or to purchase separate optimisation plugins.

Case Studies

“Makes a huge difference. Reduced number of queries and increased speed by over 20%”

“Very good cache and compression! (other options are great, too!) I combined this with WP Speed of Light and get a great performance by this. Hope you keep on the great work! ❤”

* UPDATE: Used the performance.now() function to measure the time it takes to execute the prefetching logic. The prefetch_throttle_delay value is adjusted based on the measured performance, ensuring that the prefetching logic only runs when the browser is able to handle it without impacting the user's experience.
